Default Re: ILP transformers

I've now put 126v across the 2 brown wires and am getting 38.5v on each of the two secondaries. I don't want to go to 240v on the primary just yet but would rather wait until I can hopefully confirm the correct input primary voltage.

It might be twin 55v secondaries for a 240v input to obtain a centre tapped 110vac output. Don't know for certain at this stage, just considering the possible industrial useage where it probably came from. Mind if it is a 55-0-55 at 500va for a 240v input, that would make a heavy duty power supply for an audio amplifier project. Also prices for such toroids on the well known auction site are pushing into triple figures!
