Use note
Notes and instructions for use
1. The measured output voltage of an airplane is a virtual voltage, and the correct output voltage can only be measured by connecting a load of more than 20W.
2. Input AC, output AC, not DC.
3. The 4000W mentioned above refers to the limit power when working under resistive load. The inductive load is one third of the resistive load.
Resistive load refers to tungsten filament lamp, heating wire, etc. Inductive load refers to series excitation motor, etc. Circuit board electronic products are carefully used.
4. The shell of this product is made of PC/PP flame retardant material.
