1. The WX900 is an advanced microprocessor-based protection and control unit that integrates six functions: protection relaying, metering, switch status display, temperature/humidity control, infrared detection, and intelligent voice prompt.
2. WX900 series models (L, Y, D, R, T2, T3, J) combine seven protection functions in one device: line protection, transformer protection, motor protection, capacitor protection, incoming feeder auto-transfer, bus-tie auto-transfer, and voltage transformer protection.
3. As an industry pioneer in China, the WX900 is the first protection device equipped with the independently developed DianHong PHMV1.0 operating system with proprietary intellectual property rights.
4. Built on a new highly-integrated microcontroller platform with on-chip bus architecture, the device delivers superior anti-interference performance. -
