Question for you folks.

I have some dual primary / dual secondary transformers with a voltage tap on the primary windings. The primaries are wound for 120 V with a tap at 100 Volts. If I want to use them at full rated power and my supply voltage was 220 V, would I run into issues if I series the primaries with one wired for 120 V and other on wired for 100 Volts?

The units are AMVECO MT3750DS torroids.

Thanks.

Larry C

I wouldn't forsee any problem with what you propose, provided the transformer is designed to give "full rated power" when used on the 100v taps.
Its just like having one primary tapped 100/120/220/240.
