Distinguishing features:

The buffer power supply ZBF-12-3A 17 Ah Eco 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 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/3A M1862 buffer power supply is sold without a battery.
