1. This module is a finished ZVS board without taps. Made of 1.6MM double-sided glass fiber board with stable magnetic ring performance2. Too much current and tin at the bottom of the circuit board (can be used for induction heating to avoid burnout for induction heating, maximum 300W (12V induction heating)3 It is recommended to use a switching supply with an input of 12V10A or more. This voltage range is the voltage during operation, not the voltage when the supply is no-load 4. Confirm that all connections are correct, and the positive and negative poles of the cord are not reversed. After connecting the load (heating coil or high-voltage package), turn on the again No can be supplied without load No-load will damage Please don't boot directly without load5. In induction heating, because of the heat sink, it will last longer than mini ZVS. Please pay attention to the temperature is too high to off and . Because the current is relatively during induction heating, the coil heat is also relatively . When heating, part of the heat generated by the heated object will be transferred to the heating coil, and the temperature of the heating coil will be very high for a long time.Name: ZVS BoardVoltage: DC12VMax.
