This document describes the technical features and specifications of the JK1-CL(M/H) and JK3-C thyristor controllers produced by Beijing Jiakai Zhongxing Automation Technology Co., Ltd.
This document describes the JK1-CL(M/H) single‑phase AC contact‑less SCR trigger controller, highlighting its high reliability, self‑synchronizing function, integrated structure and strong anti‑interference capability. It outlines the applicable range, including various single‑phase contact‑less switch circuits and parallel‑compensated capacitor installations.
The manual details the controller’s structure, installation options (vertical or horizontal in control cabinets), wiring connections, and testing procedures. It includes wiring tables, connection methods for DC24 V or DC12 V high‑level control signals, and safety checks before powering the device. This manual is written in Chinese.
