Our Advantages
The FUANSHI series of single-phase power regulators are meticulously designed, featuring a sophisticated control board, efficient radiator, quiet fan, and robust shell. At the heart of our regulator is the innovative control board, while the heat dissipation system showcases a state-of-the-art high-efficiency radiator paired with a low-noise fan. Our control board is equipped with a suite of advanced functionalities, including a synchronization circuit, automatic phase recognition, phase loss protection, gradual power-up, gentle shutdown, radiator over-temperature detection, current limitation and over-current protection, and serial working status indication. Impressively, the current capacity of the device spans from 20A to 200A. This power regulator seamlessly integrates with intelligent PID regulators or PLCs utilizing 0~5V or 4~20mA signals, and can also operate independently with its manual functionality. The regulator is engineered for single phase resistive load applications. Its versatility makes it an ideal choice for heating control in industrial electric furnaces, metallurgy, the chemical industry,textile machinery, and numerous other sectors.
