Its function is to convert our mains (220V 110V  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 the 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 application range, which has the advantage that the circuit can be not strictly required.Matching allows the operating frequency to change continuously and continuously. From the current situation in the ultrasound industry, ultrasonic generators are mainly divided into self-excited and separate excited power supply.The principle of the ultrasonic generator is to first generate a signal of a specific frequency by a signal generator, which may be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the transducer, and is generally applied to ultrasonic in an ultrasonic device. The frequency is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz,70khz, 100KHz.With best PZT8 in China The impedance of the transducer is less than 8 and the impedance of the transducer and welding horn is less than 40. 5times test for ultrasonic check 3hours Temperature rise detection To confirm all your transducer with horn no matching problem. The ultrasonic signal generator is composed of an ultrasonic power amplifier module that can convert 50/60 Hz industrial frequency alternating current into super audio frequency for the transducer to work, and a control module with "system protection monitoring" and "auto-tuning" functions. The control module can cut off the ultrasonic energy when the ultrasonic welding work fails, thus providing extremely high safety and reliability for the generator and the entire welding equipment.1. Really automatic frequency tracking (AFC) adapts to various sizes of welding molds and different design molds. The frequency range of automatic tracking: ±400HZ (according to 15KHZ ultrasonic for example, the mold frequency can be used for automatic frequency tracking at 14.40-15.20KHZ). Frequency tracking accuracy: ±5HZ2. Adopt CPU computer to monitor each program with fast speed, strong adaptability, built-in various protection systems, "system protection monitoring" function will respond to the following situations:   Excessive pressure leads to overload     Ultrasonic generator current is too large Welding head, horn or transducer loose or other failure Generator circuit failure Faulty cable between generator and transducer Automatic compensation for unstable power supply frequency3. The "automatic tuning" function enables the ultrasonic generator to automatically track and compensate for changes in the welding head frequency. When the temperature is too high, the surface of the welding head is worn or there is debris on the welding head, this frequency change will occur.4. Built-in fully automatic constant amplitude system, which can automatically compensate for different air pressure changes and voltage fluctuations,and can adjust the ultrasonic amplitude from 50% to 100% steplessly to meet the requirements of different welding workpieces.5.Using IGBT for power amplification, the response is fast, which is more than 100 times faster than the traditional silicon power tube, so the protection function is better. Voltage: 198-242VAC (50 / 60Hz), the output will be much weaker when AC110V input, need some adjustment, direct use is almost only used for cutting applications.Volume: 384mm * 240mm * 110mmWeight: 7KG   /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
