CCTV Power Supply Manual 8 Channel 8Amps 24VAC Wall Mount 8 Model: PAC-24WM0808(S84746) PAC-24WM0808(S84746) Overview: This PACOM Wall Mount CCTV Power Supply provides 24VAC distributed via eight (8) PTC protected outputs for powering CCTV Cameras and other video accessories. Notes: Power On/Off Switch has been provided at the Bottom of the cabinet Caution: Always test for correct output voltage ( 24VAC) before connecting power to cameras or other equipment. Temporarily power up the unit and measure the AC output voltage to avoid damage to devices. Then disconnect power before connecting external devices. 1. Mount unit in the desired location (Space unit at least 100mm from any video monitors). Do not obstruct side air vents. Use L brackets provided for bottom fixing. 2. Unplug Green terminal connector blocks from their sockets for easy installation. 3. Tech Tip: All Cameras with similar power cable length should be grouped together on the same terminal block. 4. Connect cameras or other equipment power input cables to the screw terminals side by side in pairs. 5. Screw the terminals closed, making sure that there are no loose connections. Once this is done, insert the terminal block back into its correct slot. 6. Connect the unit’s power cord to a 240VAC outlet. Switch on power to the unit. 7. Front-panel LEDs should illuminate Green if the Channel is not being used and Blue if the channel or channels are being used. Red if the Channel has a short circuit on the output lines. 8. Test the output at the camera end of each power cable to be sure that the voltage is within range as specified by the Camera manufacturer. 9. Volt meter operational range 5V - 69.9V 10. Amp meter operational range 200mA -8Amp For current load > 8 Amps ,<9 Amps Amp Meter display will Flash the current value For current Load Greater than 9.00 Amps, the Amp Meter display will read OL= Over Load. PAC-24WM0808(S84746) PAC-24WM0808(S84746) Tri-Colour LED status indicator for each output: Green Open Circuit Blue Closed Circuit < 120mA load Red Short Circuit PTC Fuse tripped CAUTION: To reduce the risks of electric shock do not open enclosure. There is no user serviceable parts inside. Refer servicing to qualified service personnel. Replace fuses with the same type and rating T1.5A/250V Wall Mount Mechanical Dimensions 280*231*83mm Procedure for resetting PTC fuse: • Remove short in the circuit. • Switch off PSU switch for a period of 30 seconds, then switch back on and PTC fuse will reset automatically. Specifications 11. Ry-NC is a normally closed relay contact. 2 3 PAC-24WM0808(S84746) PAC-24WM0808(S84746) Parallel Output Configuration By connecting more than 1 output in parallel the normal current availability can be doubled, tripled or even quadrupled 24VAC Cable Distance (meters) 5VA (208ma) 24 AWG 65m 10VA (417ma) 22 AWG 103m 24 AWG 32m 20VA (833ma) 24 AWG 16m 20 AWG 175m Normal Current Limit X 2 18 AWG 260m 22 AWG 86m 20 18 AWG AWG 87m 137m 22 AWG 43m 20 AWG 44m 16 AWG 414m 16 AWG 218m 18 16 AWG AWG 69m 109m 14 AWG 348m 14 AWG 174m 12 AWG 276m 14 AWG 659m 12 AWG 1052m Load 12 AWG 552m Normal Current Limit X 3Load Load 30VA (1.250ma) 40VA (1.667ma) 50VA (2.083ma) 24 AWG 10m 24 AWG 8m 24 AWG 6m 22 AWG 29m 22 AWG 21m 22 AWG 17m 20 AWG 30m 20 AWG 22m 20 AWG 18m 18 16 14 12 AWG AWG AWG AWG 46m 73m 116m 184m 18 AWG 34m 18 AWG 27m 16 AWG 55m 16 AWG 44m 12 AWG 138m 14 12 AWG AWG 69m 110m 75VA (3.125ma) 24 AWG 5m 22 20 18 AWG AWG AWG 7m 12m 18m 100VA (4.167ma) 24 AWG 3m 22 20 18 16 14 AWG AWG AWG AWG AWG 8m 9m 14m 22m 35m 16 AWG 29m 14 AWG 87m 14 AWG 46m 4 Normal Current Limit X 4 12 AWG 73m Load 12 AWG 55m 5 PAC-24WM0808(S84746) PAC-24WM0808(S84746) Troubleshooting 1. Power does not turn on • Check front panel leds and rear main fuse • Ensure power cord is firmly in its socket and the switch is in the on position • Ensure you have 240VAC supply to the Power Supply Unit 2. led’s are RED even • To reset PTC , turn of power and wait for 30 sec, then restart unit though there is no short circuit 3. Voltage drop is large • Use thicker guage wire 4. Camera case is hot • Check that the correct voltage is supplied to the camera 5. Amp Meter display Flashes continously • Power Supply load is approaching maximum current limit 6. Amp Meter display reads OL • Power Supply unit has exceeded its maximum load capacity. Disconnect 1 or more devices until Amp Meter shows a reading less than the maximum capacity. 6 7
