Overview

The GZDW-1B wall-mounted system is a high-reliability product designed by Xinsi Road Group with many years of development experience, and is composed of AC input power distribution part, rectification part, DC output, and monitoring part. It has the characteristics of small size, simple structure, wall-mounted installation, and no space occupation. It is mainly used in all kinds of switching stations and user changes. The system provides DC current for the instruments, meters, relay protection and accident lighting in the circuit breaker opening, closing and secondary circuits.

Model meaning

Features

♦ It has the characteristics of small size, simple structure, wall-mounted installation and no space occupation.
♦ The unique modular design of the switching power supply, redundant hot backup port
♦ Ultra-wide voltage input range, strong power grid applicability, can be used in relatively harsh environments.
♦ The charging module can be plugged and unplugged, online maintenance, convenient and fast
♦ The charging module adopts the latest international soft switch technology, with high conversion efficiency and low electromagnetic interference.
♦ Independent low-level hardware current sharing technology, typical output current imbalance between modules ±3%.
♦ The charging module has passed CE safety regulations and electromagnetic compatibility certification, which is reliable and safe.
♦ Open interface design, with powerful communication function, it is very convenient to realize the connection with the substation RTU device or power plant computer monitoring system DCS.
♦ Automatic battery management and protection, real-time automatic monitoring of battery working status and various parameters
♦ Built-in insulation monitoring relay, also can be external insulation relay or insulation monitor, flexible.
♦ Convenient and real-time monitoring of DC bus insulation.
Note: The signal box can be added according to user needs to realize the alarm function of the accident signal or the advance signal.
 Two-way AC input can be selected (one of which can choose PT100VAC power supply), PT power supply automatically limits the output power.
