Feature: 1. Multifunctional Circuit: Integrate 3 phase electrical phase detection, phase shift circuit, trigger circuit, and 3 sets of anti parallel thyristor in one, no need external synchronous transformer. 2. Convenient Adjustment: Support 0‑5vdc, 0‑10vdc, 4‑20mA signal automatic control or 10K potentiometer manual control, which can realize the stepless adjustment of the 3 phase load voltage from 0V to the grid full voltage. 3. Powerful Functions: Has the characteristics of input and output photoelectric isolation, phase shifting voltage regulation circuit and main circuit integration, high control power, stepless adjustment, high insulation voltage, etc. 4. Automatic and Manual Control: The change in the input voltage can be used to realize the automatic control of the output load power, and the potentiometer can be used to manually adjust the output power. 5. Wider Applications: The voltage regulator can be used in industrial control, lighting, transformer primary side voltage regulation and other equipment for temperature, dimming, voltage regulation controls.
