Deskripsi
Phase Sequence Detection Module
- Type: Phase sequence detection module
- Model: XXJC‑4X1‑1911
- Brand : Changzhou Power Plant Auxiliary Equipment Factory Co., Ltd.
Product Overview:
The XXJC‑4X1‑1911 is a phase sequence detection module designed for use in three‑phase electric actuator systems. Its primary role is to monitor the incoming three‑phase power supply, detect incorrect phase sequence or phase loss, and ensure the actuator motor runs in the correct direction. This prevents mechanical damage, misoperation, and downtime in critical industrial valve control applications.
