This installation manual shall also be read together with the datasheet of the product. Download the datasheet from www.polyamp.com and check the File archive where in section Datasheet you will find PSE100AC.pdf . If any problem occurs during installation please check section 10 Trouble shooting. The product is labelled as below example: PSE100AC24 Input range: 176-264Va.c. 0.71 A AC frequency: 48-420Hz Output: 24 Vd.c. 4.2 A Option: L, C • ”Type: PSE100AC24” has input code ”AC” and nominal output voltage 24 Vd.c. ”Type: PSE60ACW12 ” has input code ”ACW” and nominal output voltage 12 Vd.c. The Options are block letters separated by comma(,). You will find explanation within this manual what the letter code means. The input states the nominal input voltage and maximum input current at any conditions. It means the output is adjusted +10% above nominal voltage and close to the current limit, which is the stated output current +5% and a lowest input voltage level. Input range is the input range that the unit can operate normally. Output indicates the nominal output voltage and the rated current. The output is current limited with a so called rectangular characteristic. When the current limit is reached, which is adjusted to +5% of above mentioned nominal output current, this is the maximum current that will 2011-04-26 Temperature range is the rated operation temperature at 100% load condition. Input, output and case are galvanically separated from each other. This is a Class I insulation system, which is dependent of correct earth connection on the input. All outputs are insulated from case with minimum 2000 Vd.c. Series number is stamped on the panel under the connector The power supply type name consists of model name PSE60 and PSE100 followed by input code and output voltage. Two examples: • continuously flow. The output voltage drops very quickly down towards zero volt (depends on the series resistance of the load circuit as the unit can be regarded as a constant current generator at over current condition). We have no time limit on over current condition. 1.1 Cable and pin dimensioning The PSE series is using a DIN 41621 H15 connector intended for 3HE Euro format mounting. Each pin has a continuous current rating of 15 A @+55°C and 12 A @+70°C ambient temperature. The Uout pins are internally parallel connected and can therefore supply more current or two different loads. If the unit is equipped with sense option S this must be connected to one of the loads or a distribution point. 1.2 Inrush current limit The input capacitors are charged through an NTC resistor to reduce the input current during start up. All models has an ”output soft start” that do not increase the input current above the unit rated current during start up (approx. 0.1s). 1.3 Input Fuse There is a fuse inside the the power supply. If that fuse blows it’s an indication of a fault in the unit. Replace with new unit and send it back for repair, see section 10. Copyright 2000-2011 Page 4(13) IN NSTALLAT TION MA ANUAL PSE series AC C Inputs 2 Ins stallation n The convverter is desiigned to be mounted m in a 3U 19” ssub rack unitt. Otherwise a location only acccessible for seervice, which h meets the demand of EN609500 regarding fiire enclosuree, voltage hhazard protecction and meechanical strength shall be usedd. With optio on N, wall mounting set you cann mount the converter in any direcction on a waall or with op ptional mounting clips on DIN rail TS35 5. The converteer is convectiion cooled an nd in order too get sufficient coolingg there shall be a free air around thhe converterr. If this is no ot possible, we recom mmend the use u of an exteernal fan. On 5 V ssingle outputt voltage the case temperatture might inncreases +20 °C above ambient temperaturee. An optionaal extra cooler, ccalled T3, cann be provided on 5 V versions to lower thee operating teemperature oor increase the operatinng temperaturre range. Thee extra coooler is calledd T3. Note thaat the expecteed life of the converter iss dependaant on converrter temperatture. As a rulle of thumbb, for every 10 1 °C that the temperaturre is lowereed the expectted life is app proximately doubled.. It is therefoore crucial to cater for good venntilation andd if possible to t reduce ambient temperaturee. To meet the EMC sppecifications in the mity” use enclosedd ”declarationn of conform twisted-ppairs for connnecting inpu ut, output andd alarm. Shhielded cables are not neecessary. If the converter suppplies a DC-m motor, we recommeend an externnal parallel diode d at the motor pooles to protecct against rev verse voltages. Installattion in a 19”” sub rack : 1. Check the pinout with Figure 1. Connect the prrotective earrth pin 32. Th his provide safetyy against elecctrical shock k and is required to achievve EMC perfformance accorrding to the declaration d of o conformityy. 2. Be aw ware that if thhe sense optiion ”S” is proviided the sensse must be co onnected to the seensing point and cannot be b left open, see SSection 5 pagge 9. 3. Plug in the unit.

Bee aware that if the sense option ”S” is proovided the seense must be co onnected to tthe sensing point p and cannot be left open, seee Section 5 page p 9. Bundle the output cabbles together, separate from inpu ut. 3. 3 The conveerter output iis short-circu uit proof by a consttant current llimit which works w unlimited in time. Theerefore there is no need to fu use the load ((unless you use u multiple lo oads, see bellow). The cu urrent limit is fix xed to 105% of nominal output o current. 4. 4 Options an nd features • If thee converter iss to be conneected in paralllel at the outtput, please consult c sectio on 3 Paralleel connection n on this page. • If you u use multipple loads, please consu ult section 4 Multiple loa ads at the outpu ut on page 9.. • Checck section 6 ffor the outpu ut over voltage protectionn page 10. Polyamp A AB Copyrightt 2000-2011 Paage 5(13) INSTALLATION MANUAL PSE series AC inputs • If you intend to use alarm feature, please consult section 7 Under voltage Alarm on page 10. 5. Connect the input cables. Bundle input cables together separated from the output cables. 6. Switch on the input voltage. Beware of hazardous voltages! The output voltage can be adjusted between ±10% of nominal output voltage with the potentiometer marked V.ADJ on the front panel. Clockwise turn increases the output voltage. The potentiometer has 15 turns. If you have connected units in parallel on the output, the procedure of adjusting the output voltage is described in “Adjusting output voltage when units are paralleled on the output” on page 7. 3 Parallel connection If a redundant power supply system is requested, two or more converters can be connected in parallel. To achieve redundancy the number of converters must be dimensioned to carry the whole load even if one converter is faulty. The option C or CR series diode on the output must be provided. Connect your load to the + output after the series diode (cathode). Another reason for connecting two or more converters in parallel is to get more power. The option C must be provided and use the output with series diode. When the series diode C or CR option is used the Sense option S, see section 5 page 9, cannot be used. 3.1 Series diode on the output, option C The series diode protects the converter output from external voltage sources. If the series diode is used, we recommend to use the alarm function option B alarm circuit. The alarm relay will switch to ”ALARM” on the faulty unit if one power supply breaks down in a redundant power supply system. Otherwise there will be no alarm indication from a faulty power supply unless all units are in current limit. 3.2 Series diode with series resistor, option CR This option is an extension of 3.1 Series diode. When several PSE units are connected in parallel with so called “hot plug in” in 19” sub-rack, a built in series resistor and series diode is provided that will automatically balance the current between units. The series resistor will provide the Ud function described in section 3.4 and Figure 4. Thus no special cable arrangments are needed with this CR option. 3.3 Output under voltage alarm If one DC/DC converter fails in a redundant power system an alarm signal should be detected. The PSC has a logic open collector alarm to provide a logic signal. An optional relay dry contact output, see section 8 page 10. The figure 2, next page shows a N+1 system with two units for the load and one for the redundancy. Each Power supply has a built in; series diode (C), balancing resistor (R) and alarm Relay option B. The alarm is cascade connected. With the CR option a hot plug-in can be achieved if the output voltage is correctly adjusted. Use instruction section 3.6 -3 below. A series diode is necessary if the output is connected in parallel with another power supply or if you require redundant operation. If a converter breaks down with an internal short-circuit on the output and other converters are connected in parallel on the output, the broken unit will short-circuit the others if the series diode is not used. This might cause excessive heat or even fire in the faulty unit. 2011-04-26 Copyright 2000-2011 Page 6(13) IN NSTALLAT TION MA ANUAL PSE series AC C Inputs 3.4 Co onnecting g systems in N+1 co onfiguratio on Figure F 3.

Depending g on the impedancce of the shoort circuit (wh hether it is abrupt or merely ann overload) and a the resistancee of the loadd cables, the effects e of a short-ciircuit will vaary. 3. 3 Long cab bles reduce shhort circuit currents, c resulting in longer deelay until the fuse is blown an nd hence an iincreased volltage dip.

We do not recommend you to repair a faulty unit. All unit opened by customer will not be repaired under warranty. Check that the input voltage is within the specified limits. 2. The PSE AC-input series has a build in fuse not accessible from outside. • Measure the input resistance, if open the fuse has blown. The unit has to be replaced by a new unit or be repaired. 3. The Power supply output may be in current limit due to excessive output current or an external short-circuit on the output. • Measure the output voltage. If shows > 0.5 V the thyristor OVP, see section 7.2, might have trigged. • Disconnect the input by an external voltage breaker. • Disconnect the load. • Connect input fuse again and measure the output voltage. If the converter now starts the load was too heavy or there was a short circuit. • If there is an external short circuit, remove it. • If the load is too large decrease the load or consult your Polyamp dealer. 4. If still no improvement the unit is broken. Contact your Polyamp dealer.
