High Performance 20kHz Ultrasonic Spot Welding Machine With Digital Generator
Description:
Ultrasonic generator also called ultrasonic power supply. Its function is to convert our mains electricity (220V or 380V, 50 or 60Hz) into a high-frequency alternating current signal that matches the ultrasonic transducer. From the form of amplifying circuits, linear amplifying circuits and switching power supply circuits can be used, and high-power ultrasonic power supplies generally adopt the circuit form of switching power supplies in terms of conversion efficiency. Linear power supply also has its unique application range. Its advantage is that it does not require strict circuit matching, allowing continuous and rapid change of operating frequency.
