Granbo Ultrasonic Cleaning Generator Controller 600W-3000W Multi-Frequency 25KHz-120KHz for Industrial And Commercial Use

What is an ultrasonic generator?

The ultrasonic generator is a power supply. It transforms AC electrical energy from a power source such as a wall outlet, to electrical energy appropriate for energizing a transducer at an ultrasonic frequency. In other words, the ultrasonic generator sends high-voltage electrical pulses to the transducer.

What is the best frequency of an ultrasonic generator?

While the ultrasonic frequency of 40 kHz is by far the most commonly used frequency for ultrasonic cleaning, some applications do require a lower or higher frequency for best results. For example, larger, heavily soiled items may use a frequency of 20 kHz since this yields bigger, stronger cleaning bubbles but fewer bubbles per second. At the other end of the spectrum, some very small, delicate items may require higher ultrasonic cleaning frequencies, up to 200 kHz. In general, a higher frequency permits a higher level of intricate detail to be cleaned.
