The ultrasonic generator can monitor the frequency ultrasound power. According to different requirements of users, real-time adjustment of various parameters: The power, amplitude, and running time. Applies to:Low-power ultrasonic cleaning machine, household cleaning machine, ultrasonic generator built machine.Circuit board and vibration head (ceramic transducer) Wiring instructions: 1. Can not be energized when the circuit board is in no-load condition. 2. When cleaning, can not be energized when there is not any cleaning solution; or energized vibrator and the circuit board without any installation, which can damage the vibrator and the circuit board. 3. Vibration first two tabs, two ceramic middle lug is positive, by the and lower metal column is negative, can not be reversed;Transducer film on the ceramic sheet covered with a silver layer for the negative side,the other side of a two silver layer is positive,the smaller one is negative,when the welding power supply line must be welded to the side there are two silver layer,the other side of the vibration surface,can be pasted in the washing tub;a silver layer ceramic chip is not high temperature,the power cord when welding iron temperature should not 280degrees,iron temperature is set to 250degrees.Vibration head larger side (with screw holes) to vibrate surface can be glued to the pelvic floor cleaning, washing pots must be well grounded; Vibration head or transducer ceramic glue application head shock stick firmly to the pelvic floor cleaning; Two vibration head and coupled to the terminals on the circuit board, a board with up to two vibration head, also with supporting the use of a transducer headPositive and negative, respectively positive and negative output coupled with the oscillator can not be wrong, we have questions, advice to ety; to wash pots and grounding and the power leakage protection switch, to safety.Remarks: ! Do not directly power on and test.You must install it on the sink first, then put water in the sink and can be electrified test.Power Board:220V 100W:50W 40KHZcolour: green + silverMaterial: plastic + metalPackage Contents:1 Driver1 x Transducer1 set x accessories(Due to different production batches, the appearance color of the parts on the product may be different from the picture, the function is the same)
