The CH-105 operates with single-phase mains of 50-60 Hz 110/220 VAC, depending on the design. It is used to charge different storage batteries automatically, providing a max output power of 600 W and an output to connect load.

The unit is equipped with a built-in control and indication panel to set the charging modes and display the storage battery status. The CH-105 can be optionally equipped with the external control panel BCP-136. Install in a dry environment (IP22). The device has a reverse polarity protection of the main power and storage battery, and a current overload protection. Deep discharge and overheat protection are optional (provided that the thermal sensor DTS-135 is used).
