GZDW-1B wall-mounted DC power supply
Overview
GZDW-1B wall-mounted system is a high-reliability product designed by Xinsi Luji for many years of development experience. It consists of AC input distribution part, rectifier part, DC output part, monitoring part, etc. It has the characteristics of small size, simple structure, wall-mounted installation, and does not occupy space. It is mainly used in various opening and closing stations and user changes. The system provides DC current for the opening and closing of the circuit breaker and the instruments, meters, relay protection and emergency lighting in the secondary circuit.
Model Meaning
Product Features
◇ It has the characteristics of small size, simple structure, wall mounting, and no space.
It adopts the unique modular design of switching power supply, redundant hot backup port
