MICROCOMPUTER-BASED PROTECTION AND CONTROL DEVICE

New Products / New Technology

The WX900 is an integrated microprocessor-based protection and control device that combines six functions in one: micro‑protection, metering, switch‑status indication, temperature and humidity control, infrared detection, and intelligent voice interaction. The WX900 (models L, Y, D, R, T2, and T3) further integrates line protection, transformer protection, motor protection, capacitor protection, incoming feeder automatic transfer protection, bus‑tie automatic transfer protection, and voltage transformer protection into a single seven‑in‑one unit. It is among the first domestically developed microprocessor‑based protection and control devices to feature the Dianhong PHMV 1.0 system and to possess independent intellectual property rights. The device is built on a cutting‑edge, highly integrated microcontroller development platform, with all bus interfaces implemented directly on the chip, delivering excellent anti‑interference performance.
