Product overview

GZDW series high frequency switching DC panel power supply is a special equipment that provides DC operation power for various closing switches and relay protection devices and as a DC power supply for power station control and signal. It is widely used in various large, medium and small power plants, substations ), electrified railways, large and medium-sized buildings, industrial and mining enterprises and institutions, substations, power distribution rooms, and places where DC power is needed for emergency lighting.

Features

Two AC inputs;

It is composed of multiple independent modules, N+1 backup;

Using intelligent management, it can autonomously complete all the functions of charging, equalizing and floating charging, and automatically compensate the temperature of the battery, effectively extending the ervice life of the battery;

The monitoring function is complete, highly intelligent, equipped with a standard communication interface to realize four remote functions;

You can choose to configure insulation tester and single battery voltage inspection function;

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