The thyristor electronic voltage regulator is mainly used for resistive loads (incendescent filament, incandescent lamps,etc.), monophase A-C brushless motor, adjustable pressure range from 20Volt-220Volt, suitable for low voltage drive heaying wire. Factory use: such as cuttings tyrofoam, pearl cotton, raincoats, make it to adjust the voltage, reduce power and so on. With the bi-direcyional high-power thyristor, the current is up to 40amps, which solves the over-current problem caused by the electric resistance of the electric furnace wire when coolingis too small; it can easily adjust the output voltage of the mains at 10Volt-continuously adjustable between 220Volt, 0 delay, 0 hysteresis. Use case: Heat regulation of electric stoves and water heater, dimming of lamp and lantern, small motor speed adjustment, electric iron thermostat and so on.
