Brief Introduction

HHT3-3/38 25-180A(SSR-VA)

The HHT3-3 intelligent solid-state voltage regulator is an intelligent integrated module that combines a thyristor trigger circuit, a microcontroller controlled phase-shifting circuit, a signal detection sensing circuit, and a voltage regulation circuit. It is a complete power phase-shifting open-loop control system that can regulate the load voltage. Built in RC resistance capacitance absorption circuit and varistor protection, compatible with 4-20mA/0-5V/0-10V signals. Under signal control, the three-phase load voltage can be infinitely adjustable from 0V to the full voltage of the power grid, with a universal frequency of 50HZ/60HZ. Equipped with a linear control circuit, it has high accuracy and good stability. Widely used in various inductive and resistive loads, such as AC motor speed regulation, industrial automation, electric heating control, mechatronics, various power sources, chemical industry, textile communication and other fields; It can achieve manual and automatic control interfaces, and there is no phase sequence requirement for the AC input of the main circuit.
