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.
