Home Products SCR Power ControllerSCR Voltage Regulator
Our HGW Series SCR Power Regulators deliver precise, reliable power control for industrial heating. Featuring advanced MCU-based PID closed-loop technology for 100% linear output, they support versatile modes like constant voltage, current, and power, with zero-crossing or phase-shift triggering. Multiple inputs (4-20mA, 0-10V, potentiometer) and MODBUS RTU/TCP communication enable seamless integration. Robust protections include phase loss, overcurrent, overtemperature, and imbalance alarms. Customizable digital displays monitor key parameters in real-time. Compact, durable designs with soft start/stop (0-120s) handle resistive/inductive loads from 30A-450A, ideal for furnaces, machinery, glass, automotive, and chemical industries.
