400W 28Khz 超声波频率发生器 PCB 电路板，用于超声波清洗机

As shown in the above 25KHz ultrasound, the output frequency of the ultrasonic generator is scanned in real-time with a period of 30ms in the range of 23-28KHz. The effect is: firstly, the standing wave in the cleaning solution disappears, and the sound intensity becomes more uniform throughout the cleaning tank space. At the same power, the sound intensity becomes stronger. 其次, the stability of the sound intensity in the cleaning solution is greatly improved when working conditions such as water level, temperature, and cleaning objects change, Even when the cleaning fluid is agitated violently, the vibration will not stop, or it will recover in a short time after the agitation action stops. 5. 结论: The real-time frequency sweeping technology has greatly improved the cleaning effect of the Ultrasonic cleaning
