The microprocessor-based protection device for the power distribution cabinet is composed of highly integrated, bus-parallel-output microcontrollers, high-precision current and voltage transformers, high-insulation-strength output intermediate relays, and high-reliability switching power supply modules. This device is primarily used in switchgear with voltage levels of 110KV and below, in power plants, substations, and distribution stations. It can also be used for voltage and current protection and monitoring in some switchgear systems with voltage levels between 70V and 220V.
The product also features a large-screen LCD touchscreen for comprehensive monitoring of power quality, including voltage, current, frequency, useful power, useless power, energy, and harmonics. Users have a clear view of the operating status of the computer room's power distribution system, enabling early detection of potential safety hazards and risk mitigation.
In addition, users can choose from features such as ATS, EPO, surge protection, isolation transformers, UPS maintenance switches, and mains output branching to ensure the safety and stability of the computer room's power distribution system.
