The ZB-1 module is a device protecting against excessive discharging of the battery. It supports gel or AGM batteries with a rated voltage of 12V.

The module’s function consists in disconnecting the battery from the load in case when the danger of the deep battery discharging occurs. The ZB-1 module can operate with all alarm control panels not having such protection.

Attention! The device must detect the battery charging current from the buffered power supply so that the battery circuit can be turned on (no cold start).
