| Mar 24, 2013 at 17:31 | comment | added | Martin | Transformers used in switched mode PSUs are highly specific to the design of the PSU. You can't just extract it and use it in another circuit, unless it is the exact same design. It certainly won't work in a linear PSU at 50/60 Hz, those are iron core not ferrite which would have been chosen for the switching frequency of 20kHz to typically 500kHz, could be even higher. | |
| Mar 24, 2013 at 17:06 | comment | added | AndrejaKo | Do you have a picture of the circuit you got the transformer from? It will probably be helpful in determining the exact use of the transformer. Also if you really must salvage parts, get a transformer from a linear power supply. I personally wouldn't feel safe using that transformer to get low voltage AC, especially since it isn't marked in any way. | |
