Description

Ultrasonic power sources are often referred to as ultrasonic sources, ultrasonic generators, and ultrasonic electronics boxes. It is a major component of high power ultrasound systems. Its function is to generate a high-power high-frequency AC signal to drive the ultrasonic transducer to work. The high-quality driving power supply must ensure the stable and safe operation of the high-power ultrasonic system. At the same time, it must monitor the operating frequency, load power, capacitive reactance, impedance and other parameters of the transducer in real time, and can carry out power according to different needs of users. Adjustment of parameters such as amplitude and operation mode.

Advantage

1. High reliability, due to the introduction of ultra-high-power power electronic devices, control ICs and advanced electrical principle topology mechanisms from foreign famous factories, combined with effective soft start, soft switching technology, microsecond detection of overvoltage and overcurrent The protection technology enables the new generation of ultrasonic generators to not only greatly increase the ultrasonic output power, but also greatly improve the reliability;
2, high efficiency, abandon the low-efficiency power transformer and the traditional circuit structure, so that the efficiency of the mains input power to ultrasonic output power is as high as 95%;
3. Transducer protection, high permeability power device step-down output and widening the resonant frequency band, so that the ultrasonic transducer (seismic) is evenly loaded under relatively low voltage, optimizing the working conditions of the transducer and prolonging the use of the transducer life;
4, strong ultrasound, accurate resonance, large output power, strong explosive force, high efficiency, the ultrasonic intensity is greatly increased by 40%;
5. Resonant frequency tracking, fine-tuning the resonant frequency according to different working conditions, so that the ultrasonic equipment maintains the best working condition;
6, power, frequency, current display, output count power-off memory;
7. Amplitude adjustment and modular power adjustment make the ultrasonic output power continuously adjustable from 50% to 100%;
8. It has a demoulding function to prevent the product from sticking to the upper mold after welding; it can be automatically retracted;
9. Miniaturization and light weight - The new generation of ultrasonic generators has achieved unprecedented miniaturization and light weight. Compared with traditional generators, the volume is reduced by 50% and the weight is reduced by 40%. Small and light weight is advanced in power electronic equipment.
