Phase-shift Trigger Module SSR-3JKH
Three-phase phase-shifting trigger module (hereinafter referred to as SSR-3JK) internally integrates three-phase electric phase detection, phase-shifting circuit, control circuit and three-way single-phase random relay trigger circuit. With the support of three-phase synchronous transformer module (model TB-3), it can be automatically controlled or manually controlled by potentiometer without any external circuit or working power supply. The three-phase load voltage can be adjusted steplessly from OV to the full voltage of the power grid by generating three pulse signals that can change the conduction angle and then controlling the three single-phase follow-on solid state relays.
According to different control signals, SSR-3JK is divided into four types: E, F, G and H.
|CON0-5V: E||CON0-10V: F||CON4-20mA: G||CON1-5V: H|
For the convenience of explanation, the SSR-3JKE, 0-5V control signal is taken as the standard for introduction.
