Ultrasonic generator
Ultrasonic power supplies are divided into self-excited and other-excited power supplies. Self-excited power is called ultrasonic analog power supply, and it is called ultrasonic generator. Ultrasonic generator, also known as ultrasonic drive power supply, electronic box, and ultrasonic controller, is an important part of the high-power ultrasonic system. The function of the ultrasonic generator is to convert the mains electricity into a high-frequency alternating current signal matched with the ultrasonic transducer to drive the ultrasonic transducer to work.
The ultrasonic generator generates a sinusoidal signal or pulse signal with a specific frequency, and this specific frequency is the working frequency of the transducer. The ultrasonic frequencies used in ultrasonic equipment are 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz, and above 100KHz.
The ultrasonic generator has a feedback link, which mainly provides feedback signals in two aspects: the first is to provide the output power signal, and the second is to provide the frequency tracking signal.
Advantages of intelligent ultrasonic generator (compared to analog type):
Automatic frequency follow-up: Once the device completes the initial settings, it can operate continuously without adjusting the generator.
Automatic amplitude control: When the load changes during the working process of the transducer, the drive characteristics can be automatically adjusted to ensure the stable amplitude of the tool head.
System protection: When the system works in an unsuitable operating environment, the generator will stop working and give an alarm display to protect the equipment from damage.
Amplitude adjustment: The amplitude can be increased or decreased instantaneously during work, and the setting range of the amplitude: 0%~100%.
Automatic frequency search: the working frequency of the tool head can be automatically determined and stored.
Overheating protection: It can protect the generator from damage.
