300W Ultrasonic Cleaner Circuit Board Frequency 20K-200K
 
 
 
Detail 
 
 
Ultrasound power source is commonly referred to as ultrasonic generator, ultrasonic generator. Its role is to convert electrical energy to match the ultrasonic transducer high-frequency alternating current signal. From the amplifier circuit form, you can use the linear amplifier circuit and the switching power supply circuit, high-power ultrasonic power conversion efficiency from the general consider switching power supply circuit form. Linear power also has its own unique range of applications. Its advantage is that it can not be strictly circuit matching requirements, allowing continuous rapid changes in operating frequency. From the current situation in the ultrasound industry, the ultrasound is divided into self-excited and it excited power supply.
 
 
Description
 
The control box adopts advanced techniques, like separately - excited circuits, controlled by microcomputer,  automatic frequency tracking and frequency sweeping, etc. Compared with the traditional control box, it has better performance, more stable and reliable operation and constantly adjustable ultrasonic frequency, which can develop the potential capacity of a transducer to the maximum. The automatic tracking of the operating frequencies optimizes output matching, strengthens power and raises efficiency. With the unique frequency-sweeping operating pattern, the cleaning solution can form a fine stream of refluence, which can time-wash off the dirty uncovered by ultrasonic waves from the surface of working pieces and thus attain faster and more thorough cleaning effect and raise the efficiency of ultrasonic cleaning. At the same time, it has perfect protective capacity: over-temperature protection and over-current protection for more reliable operation; a 4-bit timer for more accurate time control to the second. With digital power adjustment, it can meet different cleaning demands. It permits optional alteration in the working state, so the operation is freer. The complete appliance is based on a building block design. With  a computer fault location and display system, its operation and maintenance are more convenient.
