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.
