MODEL AND MEANING




The GZDw DC power supply cabinet is applied to large, medium, and small power plants and substations as a DC power supply for high-voltage switch opening and closing, relay protection, automatic control, accident lighting, lighting, and audio signals under normal operation and accident conditions.
It can also be used as a DC power supply for industries such as metallurgy, railway, mining, petrochemical, postal and telecommunications, communication, medical and health, banks, hotels, high-rise buildings, and computer networks.
The microcomputer-controlled DC power cabinet can be used for unmanned and remote centralized monitoring of DC power supply in power plants, substations, and other industries.
This product complies with the JB/T5777.4-2000 "General Technical Conditions and Safety Requirements for DC Power Supply Equipment in Power Systems" standard.
