When the machine is empty, the measured output voltage is a virtual voltage, and a load above 20W must be connected to measure the correct output voltage_x005F_x000D_2. When inputting AC power, the output is also AC, not DC._x005F_x000D_3. The 5000w mentioned above refers to the limit power when working in a resistive load. The inductive load is 1/3 of the resistive load. The resistive load refers to the tungsten filament lamp, heating wire, etc., and the inductive load refers to the series motor. And so on, there are circuit board electronic products used with caution._x005F_x000D_4. The metal shell of this product must be safely grounded 1 x_x005F_x000D__x005F_x000D_ACVoltageRegulator
