Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Input 240VAC, 3.47A NOM, Output 240VAC 3.12A, VA 750.

Contains a huge and heavy transformer with three windings and two large caps. The transformer is a special (lossy) trans. used in conditioners, name escapes me.

Measured input which is 240.2VAC and the output is 249VAC (?). Is this the reason why I managed to pick it up from somewhere many years back because it is stuffed? Put a small load on in the form of a table lamp and it still showed 249VAC.

As an aside: PCs many years back had power supplies built for an input of 220VAC with the result that they blew frequently.

Is this conditioner u/s and the caps might be the only salvageable item once I check them??

My guess is its 1:1 ratio isolation transformer, so 240VAC in and 240VAC out with some current loss in between.

A simple ohms test between primary and secondary windings should show if it has a fault.

Pete.

Pete,

Thanks for that. Will check the windings as you are suggesting.
