SCR Phase-shift Triggers

I. Overview
The JKH-D4 intelligent three-phase SCR phase-shift trigger/voltage regulator adopts advanced microprocessor technology and is based on the LU-906 intelligent controller, with multiple built-in input specifications, dual digital display plus light bar, and keypad operation. It is suitable for constant-voltage or constant-current charging, electroplating, electrolysis, DC motor speed control, etc. Wiring is simple and the phase sequence need not be considered. 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-D4 intelligent three-phase SCR phase-shift trigger/controller is panel-mounted with bumpless manual/automatic switching and dynamic light-bar indication of the output level, making operation convenient. The output range is freely settable to suit heating elements such as silicon carbide rods and silicon molybdenum rods. It has a soft-start function with freely settable soft-start time, can provide upper and lower limit alarm outputs, and can provide RS232/RS485 communication.
The JKH-D4 can be used with star connection in three-phase four-wire systems.
