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.
11. Ry-NC is a normally closed relay contact.
Tri-Colour LED status indicator for each output:
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

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 • Power Supply load is approaching maximum current limit
Flashes continously
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.
