1.1. General description.
The PSU BNC04124 is intended for uninterrupted supply of CCTV systems requiring stabilized
voltage of 12V DC .
The output voltage can be adjusted with a potentiometer between 12V and 15V DC.
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).
