High-Frequency Generator for Ultrasonic Cleaning Systems

Product Specifications

Technical details and manufacturing context for High-Frequency Generator

Definition

The High-Frequency Generator is a component used in industrial ultrasonic cleaning systems, particularly in vegetable washing lines. It converts standard single-phase AC mains power (220–240 V AC, 50/60 Hz) into high-frequency alternating current, typically in the range of 20–100 kHz, to energize piezoelectric transducers. This creates ultrasonic cavitation in water, which is effective for removing soil and contaminants from vegetables. The generator employs electronic oscillation circuits using MOSFET or IGBT switching technology to produce precise high-frequency waveforms. Its output power ranges from 500 to 2000 W, and frequency accuracy is maintained within ±0.5% to ensure stable cleaning performance. The unit operates within an ambient temperature range of -10 to 50 °C and offers an efficiency of at least 90%, reducing heat generation. Protection class varies from IP54 to IP65, suitable for dusty or wet environments, and cooling can be air or water, depending on the power level. Typical dimensions are 300×200×150 mm, and weight ranges from 5 to 15 kg. When selecting a generator, it is essential to match the output frequency to the transducer's resonant frequency and to consider the power requirements of the cleaning system. Verification of model-specific parameters, such as exact output power, frequency range, and protection class, should be confirmed with the legal manufacturer or supplier. The generator is a critical component that directly influences cleaning effectiveness and energy consumption. Proper installation and maintenance, including monitoring operating temperature and ensuring adequate cooling, are necessary to prevent thermal shutdown and prolong service life. This directory entry provides reference data; actual specifications may vary by model and application.

Working Principle

The generator converts low-frequency AC power to high-frequency AC power using electronic oscillation circuits. It typically employs MOSFET or IGBT switching devices that rapidly switch the DC bus voltage to create a high-frequency waveform. The control circuit regulates the frequency and amplitude to match the transducer's resonant frequency, ensuring efficient energy transfer. The output is then applied to piezoelectric transducers, which convert electrical energy into mechanical vibrations, generating ultrasonic waves in the cleaning liquid.

Frequently Asked Questions

What is the typical output frequency range of this generator?

The output frequency range is 20–100 kHz, but it must be matched to the resonant frequency of the ultrasonic transducers used in the cleaning system. Always verify the exact frequency range with the manufacturer for your specific model.

What input voltage is required?

The generator requires single-phase AC input voltage of 220–240 V at 50/60 Hz. Ensure your power supply matches these specifications before installation.

What protection class is available?

The protection class ranges from IP54 to IP65, depending on the model. IP65 is suitable for dusty or wet environments. Confirm the actual rating with the supplier for your intended application.

How is the generator cooled?

Cooling can be air or water, depending on the power rating. Higher power units may require water cooling to maintain safe operating temperatures. Check the cooling method specified for your model.
