​Introduction
The GZDW series DC power supply cabinets are applied in large, medium, and small-sized power plants and substations. They provide the required DC power for high-voltage switch operation (opening and closing), relay protection, automatic control, emergency lighting, as well as light and sound signals during normal operation and emergency conditions. They can also be used in industries such as metallurgy, railways, mining, petrochemicals, telecommunications, healthcare, banking, hotels, high-rise buildings, and computer networks for their DC power needs. The microcomputer-controlled DC power supply cabinets are suitable for unattended, remotely monitored power plants, substations, and other industries requiring DC power.
This product meets the standard of JB/T5777.4-2000 General Technical Conditions and Safety Requirements for DC Power Supply Equipment in Electric Power Systems.
