Software Specification Basic Operation Short press the Power Switch/Volume Control knob to power on the repeater; rotate the Volume Control knob clockwise to adjust the volume to a comfortable level. Press the Up or Dn button to select a desired channel. Then the repeater will operate as you set. To achieve basic repeater functions, the radio must be in setup mode and operate in forward, reverse or bi-directional repeater mode. Repeater Hang Time When the repeater stops receiving due to signal disappearance, the transmitter will keep transmitting for a programmed time period. In this way, repeated startup of the repeater link is prevented when the PTT key is frequently pressed. The Repeater Hang Time can only be activated in forward directional repeater mode. Display Frequency Short press the Moni button to display Rx frequency of slave radio, Tx frequency of slave radio, Rx frequency of master radio, Tx frequency of master radio by turn. Monitor If the Monitor function is programmed by your dealer, long press (more than 1.2s) the Moni button to listen in activities on the current channel. The Monitor function is disabled in bi-directional repeater mode. Two operation modes listed below are provided for you to choose via the programming software. Note: In knockdown state, the Monitor function is disabled. A.
Signaling Off-Momentary
Hold down the Moni button to open the CTCSS/CDCSS, DTMF/2-Tone/5-Tone signaling squelch; release it to close the signaling squelch. B.
Carrier Squelch -Momentary
Hold down the Moni button to open the squelch; release it to close the squelch. Scan The Scan function can only be activated in forward directional repeater mode. Press the Scan button to initiate repeater scan (if scan parameter is applicable). The Scan Gap Time and Dropout Delay Time are configurable via the programming software. Note: The AUX4/5 MUST be programmed to Rx Carrier/Rx Tone/Decode Output Control to allow the repeater to land on an active channel when an eligible call is received.

TR-800 Service Manual CTCSS/CDCSS Set up talkgroups/users with unique CTCSS/CDCSS to prevent unwanted conversations on the same frequency. If CTCSS/CDCSS is set on the current channel, a CTCSS/CDCSS matching will be required on an incoming call. If not set, the radio unmutes to all calls within the communication range on the current channel. Your dealer may preset CTCSS/CDCSS on certain channels. Note: This feature does not mean that your conversation will not be heard by others. Time-out Timer (TOT) The feature allows more efficient use of channels by limiting the maximum time of each transmission. It protects the radio from damage caused by long time transmission. Once a continuous transmission exceeds the preset time (15 to1200s programmable), the transmission will be automatically terminated and an alert tone will be heard. The alert tone ceases upon the release of the PTT key. Selectable Squelch Level (SQL) Squelch levels are selectable (0 to 9) via the programming software. Voice Compandor/Scrambler The Voice Compandor/Scrambler feature may be enabled and disabled via the programming software. The Emphasis/De-emphasis function needs to be disabled while the Scrambler feature is enabled, and enabled while the Scrambler feature is disabled. High/Medium/Low Power Programmable High/Medium/Low power is selectable via the programming software. Programmable Channel Spacing Wide/narrow channel spacing is selectable via the programming software.

Programming Guide Overview This section describes programming and setup of the TM-800 radio and the front panel controller for use in both uni-directional and bi-directional repeater configurations. In the uni-directional repeater configuration, one radio operates as the receiver of the repeater and the other radio operates as the transmitter of the repeater. In the bi-directional repeater configuration, each radio can receive or transmit. However, the radio that is connected to J0102-Main will be referred to as the “master radio’ and the radio that is connected to J0104-Slave will be referred to as the “slave radio”. See the “Repeater Communication Interface & Display Unit” section for additional information.

TR-800 Service Manual
Circuit Description Repeater Communication Interface & Display Unit Setup/Knockdown (U0107D, Q0101, Q0103, Q0106, Q0107 and Q0108): The setup/knockdown mode at power-up can be configured via the HR-800 programming software. The electronic switches, Q0106 and Q0108, cause the setup/knockdown action by applying or removing voltage at the ignition control, pin15, of “J0102-Main”. After power-up, the setup or knockdown mode may be changed remotely with a signal from pin10 of “J4-Slave” or locally through the front panel SETUP. S0102 is a momentary contact switch that is debounced by the Q0103/Q0107 latch circuit. The orange SETUP LED, CR0102, illuminates to indicate the setup mode. As the setup/knockdown circuit goes from the knockdown to the setup mode, Q1 is momentarily turned on by Q0108 via the C0101/R0103 timing circuit. The push-to-talk (PTT) input of the slave radio, pin8 of “J4-Slave” is pulled low by Q0101 and keys the transmitter. The Rx LED, CR0105, will briefly flash during the moment that Q0101 is conducting.
Forward Audio Routing (U0104A, U0104D, U0115 and U0102B): The audio gate, U0104D, quarter of an analog switch BU4066B, enables and disables the audio from the front panel MIC audio input. U0104D is turned on with an active high DC level driven at the output of U0111_014 once a front panel PTT input is detected. The filtered audio output from pin5 of “J0104-Slave” and the flat audio output from pin12 of “J0104-Slave” are respectively routed to VI2 of a D/A converter, U0115. The audio gate pairs of U0112A/U0112C and U0112B/U0112D are controlled by output of AUX4 “J4-Slave”. U0104A is enabled once a valid signal is received and will route the audio to the DAC and transmitter. The external audio input, ACC Relay audio, is routed to the DAC U0115_VI1 and digitally adjusted to appropriate level for transmitter. The output from U0115_VO1 is applied to the second half of U0102, a buffer amplifier. All the forward audio will be mixed together and routed through S0101-5 to the main microphone transmitter audio, pin2 of “J0106-Main”.
Reverse Audio Routing (U0115, U0104B and U0104C): Part of the front panel MIC audio is routed to the input of U0104B, quarter of the analog switch BU4066B. The output of U0104B is also controlled with an active low input by the front panel PTT. Audio present on pin5 of “J0102-Main” is routed through S0102-7 to VI5 of U0115, which is used to adjust the audio level for proper deviation. As with the forward direction, the audio output of VO5 is applied to an analog switch U0104C. This switch turns on only if a valid signal is detected and pin6 of U0104 goes high.
Forward and Reverse Key-up (Q0102, U0103, U0107, Q0105, Q0111 and Q0116): When a valid input signal is present at the slave radio, pin6 of “J0104-Slave” will be pulled low and turn off Q0105 through two NAND gates, U0107B and U0107C, along with RPT enable trigger. A high DC level output from Q0105 will be applied to pin37 of U0110 and key the master radio PTT through output from U0111_013. The red Tx LED, CR0106, illuminates.
37
TR-800 Service Manual When the reverse key-up function is enabled, as in the bi-directional repeater configuration, S0101-8 must be on. Q0116 is a DC amplifier (buffer) for the Rx carrier signal from pin6 of “J0102-Main”. An active low state at the input of the NAND gate U0107A, one quarter of a MC14011B, will be conversed to a high state to drive the buffer for the Rx carrier signal. The active low level of Rx carrier signal, along with the OPT enable signal, causes a series of NAND gates, U0103D, U0103C and U0103B to generate a high DC level to turn on Q0102. The output of Q0102 is pulled low for pin8 of “J0104-Slave” and keys the transmitter of slave radio. The green Rx LED, CR0105, illuminates. Q0111 is used to prevent the simultaneous active state on PTT and Rx carrier signal of “J0102-Main”, which possibly causes unwanted tie condition of keying of both radios.
Accessory D-SUB 15pin receptacle (“J0103-Acc”) The accessory D-Sub, “J0103-ACC”, is connected to “J0102-Main” and “J0104-Slave” to supply Rx audio and PTT for linked radios (repeaters) or external controllers. Rx audio and PTT activation from the linked facilities are applied to the repeater for transmission.
Display Unit (U0110, PB01-PB06, K02, Q0113 and Q0118) All the functional triggers of enable and disable come from keypad PB01 to PB06. K02 is an encoder switch for front speaker audio output adjustment. A high output from pin37 of CPU U0110 will turn on Q0119, driving the base of Q0118 to go low. The backlight LEDs for the keypad, CR0107, CR0108, CR0111-CR0114 illuminate. Another backlight driver, Q0113, is controlled by Q0114 through the output from pin17 of U0110.
Peripheral Circuitry (U0108, U0109, KR00 and KR03) Operating power bus for all the electronics originates from the switch power 13.8Vdc output, pin9 of “J0107-Slave”, and goes through U0109 and U0108 to obtain the reference voltages of 9Vdc and 5Vdc. KR00 is a DPDT relay driven by transistor Q0123. The output from pin25 of U0110 will turn on/off Q0123, which activates relay KR00 to toggle the front speaker audio routes from slave radio or from master radio. KR03 is another SPDT relay for audio test requirement. A high DC level output from pin26 of U0110 will turn on Q0124 and key relay KR03. The Rx audio to the speaker is blocked and routed only to pin8 of the front RJ45 connector J0109.
IMPORTANT NOTE It is less possible to open squelch with CTCSS/CDCSS, but the CTCSS codes near 100Hz and 150Hz have a high false opening probability due to 50Hz AC power harmonics. Countries having 60Hz AC power may have false opening on 120Hz and 180Hz. CTCSS code 254.1Hz has a high probability of squelch tails.

Power Management Theory of Operation Battery Revert Circuit: A voltage reference network consisting of CR0212, CR0213, R0268, and VR0209 provides a stable voltage reference of 7.5Vdc. This reference voltage, at the cathode of VR0209, is applied to the negative input of the Over Voltage Detector U0206B-6, to the positive input of the AC Fail Detector U0206A-3, and to the positive input of the Low Battery Detector U0205B-5. Positive operating supply voltage for the integrated circuits is obtained from the TR-800 power supply through CR0212 when TR-800 is operating with AC mains. The supply voltage is obtained through CR02013 when the station is operating with the battery. During normal operation under AC mains power, the negative input of the AC Fail Detector U0206A-2 is higher than the positive input U0206A-3. The output of U0206A-1 is low and Q0224, the driver for relay KR01, and Q0216, the “BATTERY ON” driver, are turned off. When the AC mains power is lost, the voltage at U0206A-2 becomes lower than the reference voltage applied to U0206A-3. The output at U0206A-1 then goes high and turns on both Q0224, which activates relay KR01 and transistor Q0216, which provides a low level at the output point “BATTERY ON”. The “BAT ON” LED, CR0219, illuminates to indicate the DC power supply is operating. If the battery voltage falls below 10.2Vdc, the output from U0205B-7 will go high. This action turns on Q0218 that shunts the base drive to Q0224 through CR0217 and turns off the relay. Q0218 also provides a low level through CR0218 at output point “BAT LOW”. This auxiliary output might be used to key a portable radio to signal the repeater operator that the battery has exceeded the low voltage limit for the radios. Hysteresis is provided by the feedback network consisting of CR0221, R0289 and R0288 from the output of U0205B-7 to the positive input U0205B-5. The reference voltage at the positive input of U0205B-5 is increased such that the battery voltage must rise above 12Vdc before relay KR01 will reactivate and place the TR-800 back on the battery power. This latching action is used to prevent excessively deep discharging of the battery. The repeater will remain off until either AC mains returns or a charged battery is substituted for the discharged battery. The circuit consisting of C0233, R0285, R0286, CR0220, R0287 and Q0217 resets U0205B-7 to low upon the return of the AC mains power. Capacitor C0234 at the negative input of U0205B-6 smoothes the variation in the battery voltage between the Transmit radio keyed and unkeyed conditions. Capacitor C0230 at U0206A-2 input, in conjunction with C0234 at U0205B-6, ensures proper resetting of U0205B upon the return of the AC mains power. The Over Voltage Detector consisting of U0206B and resistors R0274, R0275 and R0271 monitors the DC output of the TR-800 power supply. If the voltage exceeds 16.4Vdc, the output of U0206B-7 goes high and turns on relay driver Q0224. The station switches to battery power, but there is no indication at the “BAT ON” output point. Zener diodes VR0210, VR0211, VR0212, VR0215 and VR0216 protect the electronics against damage from accidental static discharge. 40
TR-800 Service Manual Fuse F0203-15A and diode CR0215 provide protection against reverse polarity if the battery is inadvertently connected “backward”.
Variable Speed, Temperature Controlled Fan Circuit: The TL431AILP is a three-terminal programmable shunt regulator diode. This monolithic IC voltage reference operates as a low temperature coefficient zener that is programmed from 6Vdc to 12Vdc with a resistor network consisting of R0296, R0297 and an NTC thermistor Rth0201. Q0219 operates as a fast power switch between “ON” and “OFF” (similar to the PWM mode) controlled by the output at cathode of TL431AILP. The rotating speed of brushless fan is voltage controlled at collector of Q0219. Higher the temperature is, higher the power supply for the fan is, and hence faster it rotates.
Battery charging (Float Maintenance) Circuit: The battery charging circuit is intended for use with sealed lead acid gel cell batteries. The charging current, limited to approximately 400mA, is used to maintain a “float” charging condition for the battery. After operating the TR-800 station on the battery for a long period, or if the battery reaches the low battery limit of the revert circuit, the battery must be recharged with an external high-current charger. Recharging with the internal trickle charger requires an extended period of time. The trickle charging voltage is derived from AC mains. Resistor R0269 limits the charging current to approximately 400mA to a partially discharged battery (terminal voltage of 12Vdc). Once the battery is fully charged, the current will decrease to 10 to 25mA to float the battery at a terminal voltage of 13.6Vdc.
NOTE This trickle charger is intended to maintain the battery for a long period between power failures and is not intended for charging a fully discharged battery. If the battery is completely discharged, it must be removed and charged via a battery charger with higher current capability.

Glossary Master Radio: The radio that performs the transmitting functions in the TR-800 repeater station in general uni-directional application. Slave Radio: The radio that performs the receiving functions in the TR-800 repeater station in general uni-directional application. Bi-directional Repeater: A repeater configuration in which the master and slave radios perform both receiving and transmitting functions. The audio and Rx carrier signals from the receiver of the slave radio are routed to the transmitter of the master radio. Unlike the uni-directional case, though, the audio and Rx carrier signals of the receiver of the master radio are also routed to the transmitter of the slave radio. Cross-band Repeater: A repeater in which the slave radio operates in a different frequency band than the master radio does. For example, the slave radio operates on 162.075MHz in the high band VHF and the master radio operates on 452.025MHz in the 450-470MHz UHF band. Cross-band repeaters may be either uni-directional or bi-directional. Relay Delay Time: The time duration the repeater remains in Transmit mode after an active or valid signal is no longer detected. Repeater Knockdown: To deactivate a repeater or to remove it from service. Only the slave radio turns on at power-up. Repeater Setup: To activate a repeater or to place it into service. Both radios turn on at power-up (repeater functional). Single Band Repeater: A repeater in which both the slave radio operates in the same frequency band. Example: receive at 455.075MHz and transmit at 460.075MHz in the 450-470MHz UHF band. Uni-directional Repeater: A repeater configuration in which the slave radio receives signals only from the field radios and the master radio transmits signals only to the field radios.

Duplexer Instructions Electrically, a duplexer is a device using sharply tuned resonate circuits to isolate a transmitter from a receiver. This allows both of them to operate with the same antenna at the same time without the transmitter RF frying the receiver. Please check the duplexer is tuned to the correct operating frequencies before using the repeater. You can tune the duplexer using one of the following three methods: z
Pre-Tuned Method (preferred method)
Order the duplexer pre-tuned to the desired frequencies from the manufacturer or supplier. This is not a “method” of tuning the duplexer and does not require any field tuning or test equipment. Note that there must be certain frequency spacing between the Tx and Rx frequencies. This is called “spacing”. For 2m wavelength, the spacing is about 600 KHz. For 70cm wavelength, the spacing is 5MHz (duplexers with such spacing can be realized more easily). z
Visual Method
Use a tracking (sweep) generator and spectrum analyzer to adjust the pass-band and reject-band specifications of the duplexer. z
Emergency Method
The following paragraphs address a simple method to tune a “notched” duplexer such as DT04 UHF duplexer. This method is not as accurate as the visual method provided by the tracking generator /spectrum analyzer sweep setup but it is much less costly. It may be sufficiently good for all but the most exacting applications. Use this method only when the operating frequencies of the master radio and slave radio meet the requirements of duplexer. The duplexer you can order from HYT is a notched type (band-reject) only. The minimum spacing available is 4MHz for UHF band and 3.5MHz for VHF band. Note that this notched type duplexer offers a considerably narrow bandwidth. If the operating Tx/Rx frequencies for TR-800 are appreciably different from that of the duplexer, degraded performance of the repeater will result. The following procedure assumes that the duplexer is applied and the radios should be connected to the proper ports of the duplexer with the RF coaxial cables provided in the TR-800 kit. The duplexer should not be mounted on the bracket and the tuning screws of the duplexer (on the other side of the cavities, opposite to the RF connectors) should be accessible. Programming the Radios 1.
Program the master radio to the “Rx=Tx” mode at the frequency of Receive (assuming that the master radio operates as transmitter of a uni-directional repeater).
2.
Program the slave radio to the “Rx=Tx” mode at the frequency of Transmit (assuming that the slave radio operates as receiver of a uni-directional repeater).
63
TR-800 Service Manual 3.
Connect a communications test set, such as HP8921 series, or an RF signal generator to the antenna connector of the duplexer. The test set should be operating in “Generate” mode. To facilitate “hearing” during the tuning procedures, modulate the RF source with a 1kHz tone at 60% system deviation.
Tuning the Master Radio To tune the master radio of the duplexer, begin with the tuning screw closest to the antenna connector of the duplexer. 1.
Set the frequency of the communication test set or generator to the Rx one.
2.
Place the master radio in Rx frequency mode defined in Step 1 under “Programming the Radios”.
3.
Adjust the level of the communication test set or generator until the master radio emits a weak signal.
4.
Increase the level of the communication test set or generator by approximately 20dB.
5.
Adjust the tuning screw of the duplexer for the greatest rejection of the signal. This will appear as a noisier signal. Procedures: 5a. Slightly loosen the locking nuts of the tuning screws to allow the tuning screws to turn freely (but not “sloppy”) and 5b. Increase the level of the communication test set or generator to maintain an audible 1kHz tone.
6.
Repeat Step 4, Step 5, Step 5a and Step 5b for each of the tuning screws on the duplexer. Begin with the tuning screw closest to the antenna connector and finally tune the screw closest to the master radio port.
7.
Tighten the locking nuts of the tuning screws. To avoid damage to the tuning screws and to allow fine tuning of the duplexer, do not over-tighten the locking nuts.
8.
Repeat Step 5, Step 5a and Step 5b to fine-tune the master radio of the duplexer.
Tuning the Slave Radio To tune the slave radio of the duplexer, begin with the tuning screw closest to the antenna connector of the duplexer. 9.
Adjust the frequency of the communication test set or generator to the Tx one.
10. Place the slave radio on the Rx frequency mode defined in Step 2 under “Programming the Radios”. 11. Adjust the level of the communication test set or generator until the slave radio emits a weak signal. 12. Increase the level of the communication test set or generator by approximately 20dB.
64
TR-800 Service Manual 13. Adjust the tuning screw of the duplexer for the greatest rejection of the signal. This will appear as a noisier signal. Procedures: 13a. Slightly loosen the locking nuts of the tuning screws to allow the tuning screws to turn freely (but not “sloppy”) and 13b. Increase the level of the communication test set or generator to maintain an audible 1kHz tone. 14. Repeat Step 12, Step 13, Step 13a and Step 13b for each of the tuning screws on the duplexer. Begin with the tuning screw closest to the antenna connector and finally tune the screw closest to the slave radio port. 15. Tighten the locking nuts of the tuning screws. To avoid damage to the tuning screws and to allow fine tuning of the duplexer, do not over tighten the locking nuts. 16. Repeat Step 13, Step 13a and Step 13b to fine-tune the slave radio of the duplexer.
Battery Revert Overview The battery revert is an integral part of the power management system in the TR-800 repeater cabinet. This accessory allows you to cable your unit to a back-up battery which will engage in case of a power outage.
Safety Instructions Warnings: Batteries used to power the repeater stations contain great amounts of stored energy. Use caution when working with these units. Use battery terminal insulation covers at all times. Wear protective clothing and eye goggles. For safety, it is strongly recommended that BOTH the positive and negative leads of the battery cable be fused as close as possible to the terminals of the battery.
Cautions: Batteries may give off harmful or noxious fumes during charging. Provide adequate ventilation for the area where the battery is stored. If the wires leading to the battery are exposed, they can cause shorts or severe damage. To prevent damage, use a properly fused battery cable.
Note: Make sure the battery is fully charged before connected to the battery revert of the TR-800 repeater stations. DO NOT connect a battery if its voltage is below 12.0V DC. 65
TR-800 Service Manual
Battery Type The back-up battery “bank” for the repeater consists of one or more rechargeable batteries. The most readily available batteries are the maintenance free solid gel electrolyte lead-acid and nickel-cadmium (NiCd). Whichever type you choose, the battery must be designed for a service of operation that is typically sporadic and short term and may experience deep discharging before recharging. In between discharging periods, the battery must be capable of sustaining continuous, “float maintenance” charging at less than 1% of the rated capacity. Batteries in this category are called “stationary”, “general purpose float and cyclic”, “deep cycle”, or a similar term. Automotive batteries are not designed for this service and should be avoided.
Battery Capacity To determine the capacity for the battery or battery bank, you must know, or at least, estimate the longest period of time that the repeater is expected to operate with this back-up power source. Also, the percentages of time the repeater is expected to be in transmitting and receiving/standby mode must be factored in. Personal experience or that of others may give you a close approximation. If all else fails, assume a standard eight (8) hour shift operating solely on the battery with an extra hour before and another on after the shift. Ten (10) hours makes the calculation easy. The transmitting and receiving/standby time can be set equal (50% usage). The capacity of the battery is rated in Ampere-hours (Ah) and is called “C” or “1C”. This is not to be construed as the amount of current that may be drawn from the battery in an hour. Typically, battery manufacturers rate battery capacity based on the current drawn over a five (5), ten (10) or twenty (20) hour period. In terms of capacity, these are referred to as 0.2C, 0.1C and 0.05C rates, respectively. They are not linearly related; doubling the current drain will most likely reduce the time available by more than half. Ambient temperature has a profound effect on the battery capacity. At -20℃ (only 4 degrees below zero Fahrenheit!), approximately half of the capacity at room temperature is available. Example: What “size” battery do you need? Let’s assume that your customer’s repeater is in a location that experiences power outage and requires battery backup for no more than 5 hours. The repeater operates at a 66% transmit duty cycle. The transmitter is on the air for 2 minutes and the repeater is then in standby/receiving for 1 minute. The total cycle time is 3 minutes. The repeater transceiver draws 10A of current during transmitting and 2A during receiving. Therefore, for the first 2 minutes the battery must supply 12A and for the next 1 minute the battery must supply 2A. Then, the cycle repeats for a total of 5 hours.
66
TR-800 Service Manual Let the battery operating “capacity” be represented by Cop. This is based on the current drains during transmitting and receiving, the percentage of times of each and the total time required for battery operation. Cop may be represented by the following equation:
⎡ ⎛ ⎛ Ttx ⎞ Trx ⎞ ⎤ ⎟ + Irx × ⎜ ⎟ Cop = Ttotal × ⎢ Itx × ⎜⎜ ⎟ ⎜ Tcycle ⎟ ⎥ Tcycle ⎝ ⎠ ⎝ ⎠ ⎦⎥ ⎣⎢ Where: Cop = Operating capacity in Ampere-hours (A-h) Ttotal = Total time the station is on battery power (in hours) = 5 hours Itx= Total current drain during transmitting (in Amperes) =12A Irx= Total current drain during receiving/standby mode (in Amperes) = 2A Ttx= Transmit time during a single cycle (in minutes) = 2 minutes Trx= Receive time during a single cycle (in minutes) = 1 minute Tcycle = Cycle time (in minutes) = 3 minutes Therefore:
⎡ ⎛ 2⎞ ⎛ 1 ⎞⎤ ⎟ + 2×⎜ ⎟ Cop = 5 × ⎢12 × ⎜⎜ ⎟ ⎜ 3 ⎟⎥ ⎢⎣ ⎝ 3⎠ ⎝ ⎠ ⎥⎦
Cop = 55 Now, how big is it? Let’s consider the rated battery capacity, C, as a function of the Cop calculated above. An approximation to the rated battery capacity can be calculated with the following equation:
⎡⎛ Tcr ⎞ 0.1 ⎤ ⎟⎟ ⎥ C ≈ Cop × ⎢⎜⎜ ⎢⎣⎝ Top ⎠ ⎥⎦ Where:
C = Rated battery capacity in Ampere hours (A-h) Tcr = Rated battery discharge time in hours (usually 5, 10, or 20 hours) Cop = Time, in hours, that the repeater will be operating with the battery 0.1= Raise the term Tcr/Top to the 0.1 power A scientific calculator or the functions in a spreadsheet program can be used to solve the equation. 67
TR-800 Service Manual For our example, let’s consider the 55 A-h operating capacity, over 5 hours of operating with battery, and rated battery discharge times of 5 hours, 10 hours, and 20 hours. 1. Tcr = 5 hours
⎡⎛ 5 ⎞ 0 . 1 ⎤ C ≈ 55 × ⎢⎜ ⎟ ⎥ ⎢⎣⎝ 5 ⎠ ⎥⎦ C ≈ 55 A 55 A-h (0.2C) battery would provide the required energy under room temperature environment. 2. Tcr = 10 hours
⎡⎛ 10 ⎞ 0.1 ⎤ C ≈ 55 × ⎢⎜ ⎟ ⎥ ⎢⎣⎝ 5 ⎠ ⎥⎦ C ≈ 59 A 60 A-h (0.1C) battery would provide the required energy under room temperature environment. 3. Tcr = 20 hours
⎡⎛ 20 ⎞ 0.1 ⎤ C ≈ 55 × ⎢⎜ ⎟ ⎥ ⎢⎣⎝ 5 ⎠ ⎥⎦ C ≈ 63.2 A 65 A-h (0.05C) battery would provide the required energy at room temperature environment. Remember that the above calculations are approximate. Different discharge rates yield different “end of discharge” cell voltages which were not taken into account. The battery revert module is designed to disconnect the station from the battery if the input voltage to the module drops below 11 V dc. When in doubt, you can consult the manufacturer of the battery you intend to use to obtain “project planning data” charts. Or, you can “err” to the high side and add 10% to 25% to the calculated number. If the battery is going to experience extremes in temperature, the capacity will be affected. For cold climates, the capacity may need to be doubled or tripled.
Where to Buy the Battery? Most of the larger electronic supply houses will carry or can obtain the type and capacity of battery required for your application. You may be able to deal directly with some of the battery manufacturers especially if you need large quantities of the same model.
