Our Advantages
The FUANSHI series single-phase power regulator is an engineering marvel, composed of a sophisticated control board, robust radiator, efficient fan, and durable shell. The centerpiece of this system is the advanced control board, while the heat dissipation system is designed with a high-performance radiator and a whisper-quiet fan. The control board is packed with cutting-edge features like a synchronization circuit, automatic phase identification, phase-loss protection, slow start-up and shutdown mechanisms, over-temperature detection for smart radiator management, current limitation, and dependable over-current protection, alongside a comprehensive serial working status indication. Impressively, the machine's current capacity spans from 20A to an impressive 200A. This power regulator is adaptable for use with intelligent PID regulators or PLCs operating with 0~5V or 4~20mA inputs, or it can function independently with a manual interface. Ideal for single-phase resistive loads, the single-phase power regulator finds its versatile applications in the precise heating control of industrial electric furnaces and widely across metallurgy, chemical processing,textile machinery, and other dynamic fields.
