Our Advantages
The FUANSHI series of single-phase power regulators is a marvel of engineering, comprising a meticulously designed control board, efficient radiator, silent fan, and sturdy casing. At its heart lies the sophisticated control board; while the heat dissipation prowess is achieved through a high-efficiency radiator paired with a whisper-quiet fan. This control board boasts an array of advanced functionalities such as synchronization circuit, automatic phase identification, robust phase loss protection, power-on gradual start, graceful slow shutdown, radiator over-temperature alert, current limitation, and over-current protection. Additionally, it offers serial working status indication. With current capacity options ranging from 20A to a hefty 200A, this power regulator can be seamlessly integrated with intelligent PID regulators or PLCs operating at 0~5V or 4~20mA, among other configurations. Alternatively, it can function independently with its intuitive manual mode. Designed for single phase resistive loads, this single-phase power regulator is a versatile solution, ideal for precise heating control in industrial electric furnaces, metallurgy, chemical processes,textile machinery, and numerous other applications.
