JSTY intelligent three-phase SCR thyristor power regulator

JSTY intelligent three-phase SCR thyristor power regulator

JSTY thyristor power regulator, which contains three-phase potential detection, constant current source, linear amplifier, phase shift circuit, PI adjustment, power amplification, pulse shaping, high-frequency pulse transformer isolation trigger and three sets of anti-parallel SCR chips in one, the control loop (weak current part) and load loop (strong current part) are fully isolated, which can be continueinuerolled  by a 10K potentiometer, 1-5V voltage signal control, 4-20mA current signal control, to change the conduction of the thyristor Angle, the three-phase load voltage can be steplessly adjusted from 0V to the full voltage of the power grid.
