25K/28K/40K Automatic Frequency Tracking Circuit For Driving Piezoelectric Transducers
Low-power ultrasonic generator and integrated ultrasonic generator drive high-frequency transducer
The performance and structure are relatively simple. The control box adopts a microcomputer-controlled external excitation circuit, automatic frequency tracking and frequency sweeping mode. Compared with the high-power control box, it has stable and reliable operation, continuous adjustable ultrasonic power, and can maximize The energy of the transducer, and its small size, is suitable for chassis, cabinet control cabinets and line automation systems that need to generate ultrasound.
The working frequency of the low-power ultrasonic generator is automatically tracked, so that the output is better matched, the power is more powerful, and the efficiency is higher. The unique frequency sweeping method can form a small backflow and bring the dirt peeled off by the ultrasonic away from the surface of the workpiece in time. So as to achieve a faster and more thorough cleaning effect, and the energy of the transducer is more concentrated, at the same time, it has a complete protection function, overheating protection and overcurrent protection, and the work is more reliable. Low-power ultrasonic generator can adapt to various equipment requirements, flexible, simple and easy to operate.









  





Application of micro ultrasonic generator (power supply):
Mainly suitable for: cleaning batch workpieces. Such as mechanical parts, mechanical gears, mechanical parts, auto parts, auto parts, auto gears, stainless steel tableware, parts cleaning before plating, watch straps, hardware mechanical parts, filter cores, silicon wafers, lenses, spectacle frames, jewelry, glass Utensils, surgical instruments, motor rotors, stators, exchangers, radiators, furniture accessories, fins, aluminum-iron-copper adze parts, ductile iron parts, cylinder parts, shells, piston rings, hydraulic machinery, compressors, engine parts Such as pressing and punching hardware parts, the cleaning of the production process or the terminal, such as hairdressing silk or hair on the model head, real hair, etc. Etc. cleaning: high efficiency and good effect. It has amazing effect on oil stains, wax, dust and fine seams that cannot be cleaned by ordinary methods.

Product advantages:
1. Small size, easy to handle and store;
2. The operation is simple and easy to understand, and the debugging is simple;
3. Ultrasonic strength is strong, with strong penetrating power and cleaning ability.
Features:
1. Frequency sweep function: the most advanced frequency sweep circuit in the international market, which effectively protects the vibration plate;
2. All power output components IGBTs are imported components, which have the advantages of small size, high power and fast response;
3. Power tube: adopt imported Toshiba 90A/1200V imported tube to prevent the possibility of tube burning;
4. Unique sealing and anti-corrosion technology to ensure long-term stable and reliable operation of internal circuit boards;
5. The latest externally excited control circuit, the output power is as high as 96%, so that the ultrasonic cavitation density has been greatly improved;
6. The output current is a sine wave, which can prolong the service life of the transducer and the generator itself;
7. Wide-range sweep frequency: 17KHZ-68KHZ adjustable, suitable for various transducers;
8. Constant output design, the output current ripple is small, the output is more stable, and the transducer is protected from damage;
9. Output over current and short circuit protection can protect the generator power tube.
