SCR Phase-shift Triggers

I. Product introduction

    The JKH-C3 phase-shift trigger/voltage regulator adopts a high-performance switching power supply and offers multiple control input specifications with optoelectronic isolation between input and output. Without a synchronizing transformer, it can be used together with various controllers without interfering with the instruments. It is widely used in control systems with three-phase "△" connection or "Y" connection without neutral wire where the load requires continuous smooth regulation, where high control accuracy is required, or where high inrush current is not permitted, such as speed control, voltage regulation and charging of AC/DC motors. Reliable overcurrent protection ensures that damage to the SCRs in the main circuit will not cause damage to the controller; even if the trigger wires are connected incorrectly, the controller will not be damaged within a short period.
    The JKH-C3 phase-shift trigger/voltage regulator is panel-mounted, allows free switching between manual and automatic modes, and indicates output power dynamically with a light bar, making operation convenient.
    The JKH-C3 is suitable for star and delta connections in three-phase three-wire systems, and can also be used for three-phase or single-phase full-wave half-controlled rectification.
