Portable Solid State Regulator, 3-Phase Voltage Controller for Electric Furnaces & Lighting

Multi-function Circuits: Integrated three phase electrical phase detection, phase circuit, trigger circuit, and three sets of reverse parallel thyristors in one piece, no external synchronous transformer required

Convenient Adjustment: Support 0‑5vdc, 0~10vdc, 4‑20mA signal automatic control, or 10K potentiometer manual control. This allows for stepless adjustment of 3 phase load voltage from 0V to full grid voltage

Powerful functions: Input/output photoelectric insulation, phase adjustment voltage regulator circuit and main circuit integration, high control power, stepless adjustment, high insulation voltage, etc

Automatic and Manual Control: You can achieve automatic control of the output load power using the change of input voltage, and you can manually adjust the output power using the potentiometer

Wider applications: voltage regulator can be used for industrial control, lighting, transformer primary voltage adjustment and other equipment for temperature, dimming and voltage regulation
