• When measuring the output voltage when it is empty, it is a virtual voltage. It must be connected to a load of 20W or more to measure the correct output voltage.
• Input AC power, the output is also AC, not DC.
• The above mentioned 4000W refers to the ultimate power when working under resistive load.
• The inductive load is 1/3 of the resistive load. The resistive load means that the inductive load such as a tungsten filament lamp or a heating wire is a series-excited motor, etc., and the circuit board electronic products are used with caution.
• This product is a metal case and must be grounded safely.
