GZDW series cadmium nickel battery for DC panel, floating charge motor, equipped with automatic detection and alarm device, has the characteristics of long service life, no pollution, convenient maintenance, stable voltage, ultra-low internal resistance output, strong adaptability and high reliability to withstand large current impact. It is a more rational DC operating power supply device, which can be widely used in 500kV and below power substations and power plants, as well as metallurgy, mining, petroleum Radio and television, computer room, subway, high-rise building and other departments are used as DC control, signal power supply, power failure protection and breaker operating mechanism switching power supply.

This product complies with JB/T5777.4-2000 General Technical Conditions and Safety Requirements for DC Power Supply Equipment of Power Systems.

1. Dual AC input controlled by microcomputer can be switched automatically;

2. Automatic detection, display and alarm protection of AC input overvoltage and undervoltage, overcurrent, phase and zero loss

3. The charging and floating charging device adopts intelligent high-frequency switch rectifier module, N+1 redundancy, automatic current sharing, and hot plug;

4. The process of equalizing charging and floating charging of the battery is automatically switched, and can operate normally according to the computer settings. The programs such as power grid splitting and power transmission restoration realize the intelligent equalizing and floating charge management of storage battery;

5. When the microcomputer control device fails or sends out an error control command, the charging module will enter the autonomous working state, and the output voltage is the factory set safe voltage to ensure the reliability of the system operation.

6. 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.
