Note: 1. This board is a high frequency quadrate wave AC output, which cannot be carried by general induction appliances. "Such as: motors, electric fans, coil transformers, etc. can not be used directly"._x000D_2. simple resistive buck small electrical appliances, cheap resistive buck LED lights may not be used._x000D_3. Consideration should be given to the fact that the power supply should not be at full load for a long period of time when in use. If it needs to work continuously for a long time, it is recommended to run at 80 percent efficiency._x000D_4. Allow space for use to ensure that the power supply can work for long periods of time, otherwise it may cause artificial early failure._x000D_5. The load is an electronic switching power supply product. We need a high frequency diode output on our board. Because the rectifier part of many switching power supply appliances is a normal rectifier tube to save costs, connecting it to the "high frequency AC output" will cause the rectifier diode of the original appliance to heat up quickly and damage it, and the diode will break through the circuit. Eventually, the inverter board will burn out.
