1) Overvoltage protection

It is not appropriate to fix the overvoltage protection level to 1.2 times of the rated output voltage on the control circuit. It can change the R48 resistance value on the control board, reduce R48, and increase the overvoltage protection level;

2) Overcurrent protection

The overcurrent protection level has been fixed to 1.4 times of the rated DC current on the control circuit. When the rated current is adjusted, the overcurrent protection is automatically set. If you feel 1.4 times inappropriate, you can change the R51 resistance on the control board, reduce R51, and increase the overcurrent protection level;

3) Rated current setting

When the rated current is not set in the 11.2 step, the "W2 IF" current feedback trimming potentiometer on the control panel can be adjusted counterclockwise to make the DC express to the rated value when the system is running under heavy load. This is similar to the power setting of a medium-frequency power supply.

4) It stimulates the frequency

It is necessary to make it more exciting than the large resonant frequency of the tank circuit. Otherwise, the system will not operate normally due to the "clam" of its excitation frequency. It is suitable that the excitation frequency is 1.3 times higher than the possible large resonance frequency of the tank circuit.

5) Constant power output
