CCTV Power Supply Manual16 Channel =(2 x 8Channel) with Dual Volt / Amp meter

24VAC 1.5U Rack Mount

Model: PAC-24RM1616(S84745)8

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.

Troubleshooting

1. Power does not turn on • Check front panel leds and rear main fuse• Ensure power cord is firmly in its socket and switch

A and B are 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 tothe camera

5. Amp Meter display • Power Supply load is approaching maximum current limitFlashes 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.
