GZDW Intelligent high frequency DC control panel

Product Overview

The CZDW series DC cabinet use the Cadmium nickel battery ,floating charger , and equip automatic detection and alarm device . With the features of long life span , on pollution , easy maintenance and stable voltage , low internal resistance output , withstand high current impact,strong adaptability, high reliability , it is the ideal DC operating current device .  widely used in power and distribution plants which the voltage 500KV or below . It can also be applied to metallurgy, mining, oil, radio and television, computer rooms, underground railway, high-rise buildings and other industries . As DC control, signal power, power off protection and the power supply of breaker operating mechanism closing  .

This products compliance with standard : JB/T5777.4-2000  <<General technical conditions and safety requirements of electric power system DC power supply equipment>>  .

Product Characteristic

The dual-way AC inputs controlled by microcomputer can be automatically converted .There are the functions of automatic detection, display and alarm protection the AC input while over voltage, over current, missing phase . The charging and floating charging device adopts the high-frequency intelligent rectifier module , N+1 redundancy fits ,  automatic average current flow, and it can be plugged in electricity . Automatic conversion of both battery charge and floating charge process  , can operate normally according to the computer settings .Recovery of power transmission and other procedures by charge intelligent management .  When the microcomputer control device fails or the wrong control instruction is sent , The charging module enters the independent operating state . The output voltage is the factory set safety voltage  ,Ensure the reliability operation of the system .

The intelligent four-remote system provides detailed communication protocols for AC input, DC output, battery circuits, and expanded environmental monitoring , and has the intelligent interface for communication with the substation integrated automation system.
