Tips:
Precautions and instructions for use1. 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.2. Input AC power, the output is also AC, not DC.3. The above mentioned 4000W refers to the ulti  mate 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.4. This product is a metal case and must be grounded safely.
