20Khz Digital Ultrasonic Generator For Welding

The principle of ultrasonic welding by the ultrasonic digital generator 50/60 Hz current is converted into 15,20,30 or 40 kHz energy, even reach 70khz. The high frequency electrical energy is converted by the transducer is again converted into a mechanical movement of the same...

20Khz Digital Ultrasonic Generator For Welding




The ultrasonic generator, also called ultrasonic power supply, electronic box, control box, is an important part of the high power ultrasonic system. 

The main function is to generate high power and high frequency AC current, drive the ultrasonic transducer. 

The high-power ultrasonic power supply of conversion efficiency in consideration generally takes the form of a switching power supply circuit. 

The ultrasonic power supply can be divided into self-excited and excited the power supply, it is called ultrasonic generator excitation type, autonomous energy called ultrasonic controller.


Output power1000-5000W
Voltage110VAC or 220-240VAC
Range of welding time0.05-10/sec
Environment temperature5-50℃
Frequency tuning methodauto tuning
Automatic frequency adjustable range±2


Competitive Advantage:

1. High stability: All-digital integrated circuits, use of US imports of processors interference, simplify the hardware structure, improving the reliability of the system.

2. Automatic frequency tracking.

3. Strong output: The use of IGBT power modules plus his excited oscillation circuit structure, the output power is more than 1.5 times that of conventional self-excited circuit.

4. Amplitude stepless adjustment: Amplitude setting range from 10% to 100%.

5. Intelligent three protection and fault alarm: Die-current protection, frequency offset protection, total output is too large to protect. Equipment failure, the generator will stop working, and make the appropriate cause of function prompts until technician troubleshooting.

6. Intelligent closed-loop amplitude control technology to achieve the amplitude adjustment, independent of input supply voltage and load fluctuations affect the amplitude of the output remains constant.

7. Two kinds of welding mode: switch back and forth, so that a higher precision welding, soldering and better results.
