Instructions for wiring the circuit board and the vibration head:

1. In principle, the circuit board cannot be powered on under no-load conditions;

2. installed When cleaning, the power-on time should not exceed one minute without any cleaning solution;

3．60W driver board is 1A vibrating head is connected to the circuit board terminal in parallel, and a circuit board is used together with a vibrating head;

4．120W driver board is 2 vibration heads are connected to the circuit board terminal in parallel, and a circuit board is used together with 2 vibration heads;

5．180W driver board is 3 vibration heads are connected to the circuit board terminal in parallel, and one circuit board is used together with 3 vibration heads;

6. OUT+ is connected to the positive electrode of the transducer (vibrator), OUT- is connected to the negative electrode of the transducer (vibrator), and the positive and negative electrodes of OUT are respectively connected to the positive and negative electrodes of the transducer (vibrator),

Remember not to make mistakes.

(Note: The voltage of the output terminal on the circuit board is about 400V, pay attention to safety, it is best to have a leakage protection switch on the input power supply to ensure safety!)

Note: This circuit board is only provided for DIY by ultrasonic enthusiasts, and no drawings are provided.
