Title: How to spice up my ultrasonic cleaner?
Post by: Hank on December 18, 2024, 05:58:22 pm

I've got an Emmi-5 Us cleaner, it's got a small transducer epoxied to the tub, and I want more cleaning power!
The output stage consists of 2 X IRF830, and the transducer is fed via a transformer, so by the looks of it.
I've got a 60W transducer from Ali >:D and I was wondering if this will do the trick, but my knowledge about these things does not really suffice, hence me posting over here.
So the question is: does a transducer of 10 W have the same reactance as one of 20 W, and do I need to double the output voltage, or how does it exactly work, don't want to let the magic smoke out yet! |O

A driver for a 10W transducer is not going to drive a 60W transducer properly.

And because the driver + transducer is probably more exensive or similar cost to a whole new ultrasonic cleaner, you're probably better off to buy a decent complete one. Attempting to remove the transducer to replace it with another will be another headache.
