The 5000W AC voltage regulator can easily adjust the output voltage between 0 and 220 volts for electrical equipment with different voltage requirements. Thyristors are mainly used for resistive loads (electric filament incandescent lamps, etc.). Most single-phase AC motors are also available (but not guaranteed). This product is not a variety of substitutes, and cannot replace the battery charger of electric vehicles, nor can it drive electrical appliances that use switching power supplies (such as 110v TVs, stereos, refrigerators, air conditioners, and electric rice cookers with computers.), nor can it drive induction cookers. , Energy-saving lamps. . The motor governor adopts aluminum casing, which has good heat dissipation effect and can effectively prolong the service life of the product. Power: 5000W (instantaneous limit power of resistive load), power usage should be reduced for a long time, it is recommended to use efficiency within 2200W of resistive load: more than 90% Working voltage: AC 220V Adjustment voltage: AC 0-220V (from high to low can reach 0, from low to high, it is adjusted from about 20V) Note that you must connect the load first and then adjust the voltage. Quantity: (1 Piece) AC Voltage Regulator' other products not included Size: Size: L84.8*W70*H40mm, excluding protruding knobs and joints.
