1.1. General description.
The buffer power supply is intended for uninterrupted supply of CCTV systems requiring stabilized
voltage of 12V DC (+/-15%). The PSU supplies voltage of 13,8V DC and total current capacity of:
1. Output current 8x1A + 1A battery charging
2. Output current 8x0,87A + 4A battery charging
Total current of the rec battery is max. 11A.
The PSU is constructed on the basis of the switch mode PSU. The PSU is characterized by high energy
efficiency and is housed in a metal enclosure (color RAL 9003) with battery housing for one 17Ah/12V battery. The
power supply unit enables transmitting power and video using a 75 ohm coaxial cable integrated with two power
wires (YAP type). Additionally, it is equipped with BNC sockets for connecting the video signal. The power supply
outputs are independently protected by melting fuses or PTC polymer fuses. Failure (short circuit) in the output
circuit will activate the melting fuse or PTC fuse and disconnect the circuit from DC power (+ U). Fuse failure is
indicated by switching off the corresponding LEDs: L1 for AUX1, etc. In addition, the FPS output (hi-Z state) and
LFPS LED are activated and the relay contacts change their position. The PSU is housed in a metal enclosure with
signaling panel equipped with a microswitch indicating door opening (front cover).
