Our Advantages
FUANSHI series single-phase power regulator consists of control board, radiator, fan, shell, etc. The core part uses control board; the heat dissipation system uses high-efficiency radiator and low-noise fan. The control board has functions such as synchronization circuit, automatic phase identification, phase loss protection, power-on slow start, slow shutdown, radiator over-temperature detection, current limitation, over-current protection, serial working status indication, etc. The current capacity of the whole machine ranges from 20A to 200A. The power regulator can be used with intelligent PID regulator or PLC with 0~5V or 4~20mA, etc., or it can be used independently with manual function. The load type is single phase resistive load. Single-phase power regulator can be widely used in heating control of industrial electric furnaces, metallurgy, chemical industry,textile machinery and other fields.
