: NOTE:Do not connect to electrical appliances with switching power supply. The output has to connect to load. If there is no load connected to the output. The voltage at the output will not change. Input Voltage: AC110V/220V Output Voltage: AC10-220V Rated Current: 25A Maximum power: 6000W (resistive load limit power) Features: Using the new bidirectional high-power thyristor, the limiting current can reach 100 amps, which solves the overcurrent problem caused by the electric resistance of the electric furnace wire being too small in the case of cooling It can easily adjust the output voltage of the mains, and adjust it between 0-220v for use by electrical appliances. Can achieve the effects of dimming, temperature regulation, and pressure regulation. Power: 6000W (resistive load limited power), the power should be reduced for a long time, it is recommended to use the resistive load at room temperature within 3000W (key parameters) Note:This product is AC input, AC output, can only step down, must be connected to the load to adjust the voltage, the output must be connected to the load, it is useless to connect a multimeter without load, it is not a transformer, if there is no load connected to the output, the output voltage will not Change. This product is not a panacea, it cannot replace the battery charger of an electric vehicle, nor can it drive electrical appliances that use switching power supplies (such as 110v TV stereos - refrigerators - air conditioners - rice cookers with computers), nor can it drive induction cookers and energy-saving lamps. Note that the plastic cover on the connector is easy to break if you use too much force. Package included: 1* Electronic Regulator
