30Khz Higher Power Ultrasonic Control System with Standard 7inches Display
|Voltage||220V or 110V|
|Application||Plastic Welding Machine|
Ultrasonic generators, commonly referred to as ultrasonic power boxes, ultrasonic sources, and ultrasonic power supplies. Its function is to convert our mains (220V or 380V, 50 or 60Hz) into a high frequency AC signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and a high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own range of applications. It has the advantage of not requiring strict circuit matching and allowing continuous and rapid changes in operating frequency. From the current situation in the ultrasound industry, ultrasonic generators are mainly divided into self-excited and its exciting power supplies.

Comparing with the old system, we have further upgraded the entire system.
1. The system resonance is changed to the anti-harmonic point, which has better control of the transducer temperature.
2. Frequency control speed is faster than before
3. The power measurement circuit only calculates the power of the transducer, and the power consumption of the power box is not counted.
4. Higher power accuracy, chip AD is 16 bits, the maximum value is 65535, (Previous system chip AD is 12bits, the maximum value is 4095). the power measurement is reduced from the previous 10% error to 3%
5. Motherboard design power capacity 6000W, (the power capacity of previous system was 4000w)
6. Magnetic scale adopts differential signal, anti-interference effect is good, (Previous system was using single-ended signal)
7. Better design, standard display 7 inches.
8. The output control line has short-circuit protection and will not burn the electric box due to wiring errors.
