5000W High Power Electronic Voltage Regulator This product 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 and energy-saving lamps. Specifications: Product Name: 5000W AC Voltage Regulator Dimensions: L84.8*W70*H40mm, excluding protruding knobs and joints. Power: 5000W (resistive load instantaneous power limit), the power should be reduced for a long time, it is recommended to use within 2200W of resistive load (key parameters, please pay attention) Efficiency: more than 90% Working voltage: AC 220V Adjustment voltage: AC 0-220V (from high to low can be adjusted to 0, from low to high is about 20V) Pay attention to connect the load first and then adjust the voltage.
