28KHZ/40KHZ 300W-3000W Ultrasonic Generator PCB Circuit Board Assembly For Cleaning Machine

Ultrasonic Generators which adopts advanced high speed single chip microcomputer control technology and possess new circuit design theory,it is a new generation of multi-functional ultrasonic cleaning power.
The control box adopts high speed single chip microcomputer controlled digital frequency synthesis technology with half bridge circuit drive which is stable and low power loss.
Digital ultrasonic power is adjustable. Thus it is more flexible and more efficient.
Its complete protection function which include overheat alarm and over-current alarm make the work become more reliable.

Ultrasonic power source is usually called ultrasonic generator, ultrasonic generator. Its function is to convert electrical energy into a high-frequency alternating current signal matching the ultrasonic transducer. From the form of amplifying circuit, linear amplifying circuit and switching power supply circuit can be used, and high-power ultrasonic power supply generally adopts the circuit form of switching power supply considering the conversion efficiency. The linear power supply also has its unique application range. Its advantage is that it does not strictly require circuit matching and allows the operating frequency to change continuously and rapidly. From the current situation in the ultrasound industry, ultrasound is mainly divided into self-excited and externally excited power supplies.

The principle of ultrasonic power supply is to first generate a signal of a specific frequency by a signal generator. This signal can be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the transducer, which is generally used in ultrasonic equipment. It is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz; 100KHz or above has not yet been widely used. But with the continuous development of precision cleaning in the future. It is believed that the use area will gradually expand.

Its accurate timer which calculate results has four numbers, guarantee the quality of your work.
The screen can display status of work mode,frequency or current according to your requirement.
