How does ultrasonic cleaning remove dirt? Simply put, it relies on the invisible "bubble explosions" in the water. When high-frequency sound waves propagate in water, they constantly tug on the liquid, producing countless tiny bubbles. These bubbles have a very short lifespan and are immediately burst by the surrounding pressure as soon as they form. Don't underestimate an explosion. Billions of bubbles burst simultaneously on the surface of the workpiece, and the accumulated impact force is enough to "shake" stubborn dirt off the surface of the object. This phenomenon is known as the "cavitation effect" in the professional field, and it is also the fundamental reason why ultrasonic cleaning can wash quickly and cleanly.

To achieve cavitation effect, a core component - high-frequency switching DC power supply is indispensable. Its role is somewhat like a "tuner" in the field of sound: the mains power we use in our daily lives is low-frequency AC power of 50 Hz, but to make the transducer work, we need to feed it high-frequency electricity of 20000 Hz or more. What this power supply does is conversion work - first smooth the AC power into a stable DC, then use fast switching technology to cut the DC power into high-frequency pulses, and finally deliver them to the transducer.

In some situations where high precision cleaning is required, such as the cleaning of precision electronic components or medical devices, the stability of the power supply is crucial. At this point, a 12V 1000A low ripple rectifier will be used. The so-called 'low ripple' refers to the pure and stable output of the DC electrode, with almost no fluctuations. This high-quality current can make the transducer vibrate more uniformly and stably, thereby generating more consistent and softer bubbles, which can ensure the cleaning effect without damaging the precise surface of the workpiece.

After receiving high-frequency electrical pulses, the transducer will start to vibrate at high speed - more than 20000 times per second. This vibration is transmitted to the water in the cleaning tank, resulting in the cavitation effect mentioned earlier. Throughout the entire process, the power supply will automatically fine tune the frequency to ensure that the transducer is always in optimal working condition, just like a sound engineer letting a singer sing in the most comfortable range.
