Features
◊The dual channel AC input controlled by a microcomputer can automatically switch;
◊Automatic detection, display, and alarm protection for AC input overvoltage, undervoltage, overcurrent, phase loss, and zero loss;
◊The charging and float charging devices adopt intelligent off frequency switch rectifier modules, N+1 redundant matching, automatic current sharing, and can be plugged in with electricity;
◊The process of battery equalization and float charging automatically switches and can operate normally according to the computer settings. Implement intelligent float charging management for batteries through programs such as grid disconnection and restoration of power transmission;
◊When the microcomputer control device malfunctions or issues incorrect control commands, the charging module enters the working state, and the output voltage is the factory set safe voltage, ensuring 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 comprehensive automation system.
