quote I made from post 9Gonna see if I can get a step down convertor at work tomorrow and check it out.
If it was something lower powered - RS components (and probably various others) used to sell mains transformers with 2x 110V primaries, you wire them both in parallel for 110V or series for 220V.quote I made from post 9
Gonna get a 500w 220-110v convertor tomorrow, it should be enough to power the unit, in the meantime that is.
They have to be identical primaries - or one will get more volts than the other.just a thought,if both transformers are 110v, then wire the primaries in series to test it.
You want the 110V primaries in series, and the identical secondaries in parallel - otherwise, any current draw will exacerbate any imbalance between the two.In general you can only place the primaries of identical transformers in series and that's only of the secondaries are also in series.
