What Is The Operating Voltage Of The Ultrasonic Welder Transducer?

There are many kinds of ultrasonic welder transducers, according to the application can be divided into ultrasonic welding transducer, ultrasonic cleaning transducer, ultrasonic cutting transducer, according to the power and 18K, 20K, 28K, 35K ultrasonic transducers. Their resonant voltage is also different, which is to introduce the working voltage of ultrasonic transducer for you.

The resonant voltage of different types of ultrasonic welder transducers is also different, and this voltage is changing. In the case of frequency resonance, the voltage at both ends of ultrasonic transducers is the lowest, about 800V. Note that this voltage is a high frequency voltage, which cannot be measured by a common multimeter.

Take 1500W ultrasonic welding transducer as an example: The ultrasonic transducer needs the ultrasonic welding generator to provide 1000V--2000V excitation voltage to drive the ultrasonic transducer to work, and the working current is about 2A; Under the condition that the ultrasonic excitation voltage is unchanged at 1000V, the maximum working voltage of the ultrasonic vibrator is limited. The low-power ultrasonic vibrator generally does not exceed 1KV, and the high-power ultrasonic vibrator generally does not exceed 3KV. Otherwise the piezoelectric ceramic of ultrasonic transducer will be repolarized or broken down by ignition!
