I want to step down a 240Vpeak signal to 24. Anyone know where I can get a transformer to do this? Also does frequency have a dependence on a transformer? The signal I am looking at has around 55Khz frequency. Thanks for your help
You won't be able to find a transformer for that frequency, unless you are lucky. You will have to wind your own. Probably a ferrite core is best, depending on your power level, which you did not mention, and is an important design factor. If this is a very low power signal (you do use the word signal), perhaps a capacitive or resistive voltage divider will be enough. Or search for an audio signal transformer. .
