Overview: This PACOM Rack Mount CCTV Power Supplies provides 24VAC distributed
via sixteen (16) PTC protected outputs for powering CCTV Cameras and other
video accessories.

Notes: 2 Power On/Off Switches have been provided for each of the 8 Channels at the
rear of the Rack case

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 rack location. To maintain Air Circulation, allow a
minimum gap of 50mm on both sides and above the rack mount unit.

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. Select the power on switch A or B for each of the 8 Channels

7. Connect the unit’s power cord to a 240VAC outlet and secure with safety clip. Switch
on power to the unit.

8. 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.

9. Test the output at the camera end of each power cable to be sure voltage is within
range as specified by the Camera manufacturer.

Tri-Colour LED status indicator for each output:

10. Volt meter operational range 5V - 69.9V

11. 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.

12. RyA and RyB are N/C relay contact.
