GZDW Intelligent High Frequency DC Control Panel
Type meaning
Structure Feature
◆Two-way AC input controlled by microcomputer can be automatically converted;
◆Automatic detection, display and alarm protection for AC input over/under voltage, over current, phase and zero deficiency;
◆The charging and floating charging device adopts an intelligent high-frequency switching rectifier module, N+1 redundancy is combined, automatic current sharing is realized, and the charging and floating charging device can be plugged and unplugged with electricity;
◆The battery charging and floating charging processes are automatically switched and can operate normally according to the computer settings. The intelligent floating charge management of storage battery is realized by the procedures of power grid disconnection, power transmission restoration and the like;
◆When the microcomputer control device fails or sends out an error control instruction, the charging module enters an autonomous working state, and the output voltage is the factory-set safe voltage to ensure the reliability of the system operation;
◆The intelligent four-remote system provides detailed communication protocols for AC input, DC output, battery circuit and expanded environmental monitoring, and has an intelligent interface for communication with the substation integrated automation system.
