OK. a search gave me a bunch of old threads to bump.........
A 600w "minuteman" UPS, 1:1 isolation transformer, has a single 120vac primary, [ blue / white ] and three secondary choices - other colors, all coils read equal ohms.......there is grounding between coils to disrupt capacitive coupling.
Is it possible to re-tie the groups of coils, so as to provide a center-tapped 240 vac primary, or is this going to cause issues with phasing.......among other things
The goal here, is to employ the #8 winding that would normally become the [ battery driven ] primary when power failed, so as to reap a rectifiable source of 240 volts High amp DC
