Details
The ZBF-12-4A-17Ah M1862 buffer power supply has been designed to ensure continuous supply for devices requiring 12 VDC stabilized voltage (adjustable within 10.5-13.8 V range). Its switch-mode converter shows 74% efficiency and provides stable output DC voltage (+/-1% of the set value, ripple and noise level below 100 mVp-p).
During normal operation, the output voltage is converted by the SMPS from AC or DC power network, and the attached rechargeable battery is maintained in a charged state. In the case of a power network outage, the power is supplied by the rechargeable battery instead. There is a protection against battery deep discharge.

Key features:
- wide supply voltage range: AC 88...264 V; DC 124-370 V
- output protection: short-circuit, overload, overvoltage
- separate battery charging path and consumer power supply path
- high efficiency (74%)
- small size and weight
- high reliability (MTBF = 304,000 hours)
