Our Advantages
The FUANSHI series single-phase power regulator is an amalgamation of precision engineering and high-quality components. It boasts a control board, efficient radiator, whisper-quiet fan, and sturdy shell. At its heart, the control board orchestrates the system, delivering unparalleled performance. The system's heat dissipation is optimized with a high-efficiency radiator and a fan that operates almost silently, ensuring the device remains cool even under demanding conditions. The control board is a powerhouse of features, incorporating a synchronization circuit and automatic phase adjustment. This robust system also provides phase identification, phase loss protection, and a gentle power-on slow start and shutdown. Over-temperature detection through the radiator, current limitation, and over-current protection ensure the unit's longevity and reliability. It elegantly displays the serial working status and supports a current range from 20A to 200A. Designed with versatility in mind, the power regulator adapts seamlessly to various configurations. It integrates with intelligent PID regulators or PLCs using signals such as 0~5V or 4~20mA, and can also function independently with a manual feature. Ideally suited for single-phase resistive loads, this regulator shines in applications like heating control for industrial electric furnaces, and extends its utility across industries such as metallurgy, chemical processing, and textile machinery.Its adaptability makes it a perfect choice for various industrial sectors.
