The 28K400-watt transducer is a high-frequency and highly efficient ultrasonic energy conversion device, with a fixed frequency of 28KHz and a powerful 400-watt output as its core advantages. Relying on the piezoelectric effect principle, it can efficiently convert electrical energy into high-frequency mechanical vibration, forming energy-dense ultrasonic waves. These waves can quickly penetrate thick media and reach complex areas such as micro-pores and crevices, powerfully breaking down stubborn dirt, grease and microorganisms. Military level of piezoelectric ceramics with high strength alloy materials, combined with precision encapsulation process, to ensure that in - 10 ℃ ~ 60 ℃ environment stable operation, low vibration attenuation rate to 5% / 1000 hours, using life over 8000 hours. The straight-handled handheld design is ergonomic, weighing only 0.9kg. It is equipped with a quick-plug interface, allowing connection to the main unit in just 3 seconds. It can support continuous high-intensity operation for 2 hours without getting hot. It is widely suitable for industrial cleaning, laboratory handling, food processing, and medical pretreatment scenarios, making it a high-performance tool that combines power and portability.
