Battery charge controller (КЗА)

The controller manages a stand-alone power system consisting of a battery bank, a charger, an inverter and an ATS circuit.
The controller can:
- monitor the battery voltage, with a digital display of the present battery voltage;
- control the charger and issue an inverter start/stop signal according to the state of the grid and the battery's depth of discharge;

Distinctive features:

• The controller measures and displays the voltage applied to the "Usupply(meas)" input. The measured voltage also serves as the controller's supply voltage.

• To control the inverter, the controller has output contacts (a changeover group) marked "Inverter".
