28KHZ 2000W 220V Digital Ultrasonic Generator PCB Parts Circuit Board For 200L Industrial Ultrasonic Cleaner

The digital ultrasonic circuit board circuit requires different cleaning frequency bands for different cleaning materials in the industry, and the ultrasonic transducers that need to be connected are also different. In order to improve the adaptability of the ultrasonic generator to transducers in different frequency bands, a closed-loop control system is designed with frequency setting by the upper computer and frequency tracking by the phase-locked loop circuit
