GZDW Series Phase-Controlled DC Power Supply.It is a specialized device designed to provide DC operating power for various circuit breakers and relay protection devices, as well as DC power for power station control and signaling. It is widely used in power plants of all sizes, substations, electrified railways, large and medium-sized building and industrial substations, distribution rooms, and locations requiring emergency lighting.

System Features

Utilizes a phase-controlled silicon rectifier charging method, suitable for DC power supplies for alkaline batteries with higher charging voltages.

Adopts intelligent management that autonomously completes charging, equalizing, and float charging functions, and automatically provides temperature compensation for the batteries to effectively extend their lifespan;

Offers comprehensive monitoring with high intelligence and is equipped with standard communication interfaces to implement four-remote functions;

Optional configuration of an insulation tester and a single battery voltage inspection function;

The system can be expanded with additional functions: adding inverter AC power distribution output and a DC/DC conversion module to achieve DC48V (24V) output.
