The PSDCB09129C buffer power supply has been designed to ensure continuous power supply for devices requiring 12 VDC (+/-15%) voltage. The outputs provide 13.8 VDC voltage. Additionally, the power supply charges the battery (not included).
Operation options:
Operation options:
1. Output currents: 9 x 1 A + 1 A (battery charging)
2. Output currents: 9 x 0.77 A + 4 A (battery charging)
The maximum total output current is 11 A.
2. Output currents: 9 x 0.77 A + 4 A (battery charging)
The maximum total output current is 11 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 a 12 V 17 Ah rechargeable battery and is equipped with a microswitch for signalling door opening.
