Ultrasonic cleaner repair
« on: December 27, 2020, 06:29:34 pm »
I have a cheap 50W ultrasonic cleaner that worked fine at first, then it would only start working after I smacked the stainless steel tank and now it wont even start anymore.

Not sure what could be the issue here and I have no clue if it is a power supply issue or a faulty transducer as it is a ceramic type and not an "industrial" one.

While it was working, I was able to get a 40 KHz, 320V sinewave output on my DMM but now it is dead and I have no way of generating such a signal with an audio amplifier or a variac.

How does one test such a transducer?

I am not sure how to proceed with troubleshooting the device so any help would be much appreciated.
