Details
The PSUPS20A12CR buffer power supply has been designed to ensure continuous power for CCTV devices requiring 12 VDC or similar stabilized voltage (+/-15%). It has two circuits, one (5 A) for a DVR (the voltage is stabilized at 12 VDC level and does not depend on the current voltage of the rechargeable battery), and the second (16x 0.8 A) for CCTV cameras (with rated voltage of 13.8 VDC). Some power supply options:
1. 16x 0.8 A (cameras) + 5 A (DVR) + 2 A (battery charging)*
2. 16x 0.7 A (cameras) + 5 A (DVR) + 4 A (battery charging)*
3. 16x 0.4 A (cameras) + 5 A (DVR) + 8 A (battery charging)*
*The total current should not exceed 20 A.
2. 16x 0.7 A (cameras) + 5 A (DVR) + 4 A (battery charging)*
3. 16x 0.4 A (cameras) + 5 A (DVR) + 8 A (battery charging)*
*The total current should not exceed 20 A.
In the case of a power failure, the circuits are immediately switched to battery power. The power supply unit is based on a highly efficient module operating in switching mode. The metal housing (RAL 9003 color) can accommodate two 12 V / 17 Ah rechargeable batteries and is equipped with a microswitch for signalling door opening.
