  • Reviews (0)


  • Universal, extra-wide range of input voltage: 88…264 VAC, 124-370 VAC;
  • Output protection against excessive voltage, overloading, short circuit;
  • Battery charging circuit separated from the main output circuit;
  • High efficiency (81%);
  • Small size and weight;
  • High reliability (MTBF: 304000 hours).
The buffer power supply ZBF-12-3A 17 Ah M1862 has been designed to ensure continuous supply for devices requiring 12 VDC stabilized voltage (adjustable within 10.5-13.8 V). Its switch-mode converter shows 74% efficiency and provides stable DC voltage (the tolerance of the set output voltage is +/-1%, 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 no protection against battery deep discharge, which allows full use of the battery capacity.
The ZBF-12V/4A M1862 buffer power supply is sold without a battery.
