The JK3-CL SCR controller is a three‑phase AC contact‑less switch trigger device designed for a wide range of applications, especially parallel‑compensated capacitor banks. It features high‑reliability zero‑cross triggering, self‑synchronization, integrated structure, and strong anti‑interference capability.
This manual provides an overview of the controller's specifications, operating principle, mechanical structure, wiring diagrams, installation methods, and step‑by‑step testing procedures. It includes detailed connection tables, recommended wiring practices, and safety checks before commissioning. This manual is written in Chinese.

It accepts a DC control voltage of 5‑24 V with a minimum current of 1 mA, or it can be driven by relay contact inputs.
Connect terminal 2# to the DC24 V positive lead and terminal 3# to the DC24 V negative lead.
Use a resistive load such as a 100 W incandescent lamp or an electric furnace that matches the working voltage.
