1. Technical description.
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 features 4 independently adjustable channels for power supply in the range of
4x12÷18VDC/4x1A. This enables compensation of voltage drops in complex CCTV systems. The current efficiency
of the PSU is:
1. Output current 4 x 1A + 0,2A battery charging
2. Output current 4 x 1A + 0,5A battery charging
Total current of the rec battery is max. 4,5A.
