The sine wave excitation voltage of about 240V-330V shall be provided, and shall not be lower than or higher than the voltage in this range. The transducer will not work when the voltage is lower than this voltage, and the piezoelectric ceramics of the transducer will be damaged when the voltage is higher than this voltage.

Provide the corresponding inductance parameter. The more or less inductance is used to measure the current of the circuit board. If the inductance is small, the current to drive the transducer will be small, and the vibration will also be small. Provide sufficient capacitance matching the transducer.

The driving circuit board of the self-made ultrasonic cleaning machine can drive the frequency of 28khz-40khz and the power of 50W-120W.
