Ultrasonic Cleaner
Ultrasonic cleaning is a means of removing dirt and surface contamination from intricate and/or delicate parts using powerful high frequency sound waves in a liquid (water/detergent/solvent) bath.
An ultrasonic cleaner contains a power oscillator driving a large piezoelectric transducer under the cleaning tank. Depending on capacity, these can be quite massive.

A typical circuit is shown below. This is from a Branson Model 41-4000 which is typical of a small consumer grade unit. The H and N are Hot and Neutral of the 115 VAC line. WARNING: Line connected input. Use isolation transformer for safety when troubleshooting.

Well I can remember months ago when I knew nothing about electronics ;D, and I came across these types of schematics and thought, (what the) and now seeing frowning faces in them, well that's just scary :o ;D.

So far so good hotwaterwizard, how are you drawing this?

Are you using a special program or are you using paint and putting some pre-drawn symbols togeather?

Well spotted tnk2k, I completely missed that!  ;D

The output's also pulsed 80kHz not 90Hz.
