I have a 480 volt only transformer and DC power supply built a bit differently than any I've seen. There are six separate little wire coils, three primary and three secondary. No taps at all, one end of each coil goes to the outside world. The other end of each set of three is wired together to form a node, a sort of neutral.
Here's ASCII art for the primary: (the secondary is a mirror image)
L1-----Coil1------ | | L2-----Coil2------ | | L3-----Coil3------
OK, I don't have 480 three phase. My question, can I start re-wiring this to use 240 three phase or even single phase? I'd like to try wiring the primary coils: L1 to L2, L2 to L3, L1 to L3. I'd also like to try single phase: put all primary coils in series, all secondary coils in series.
Will this just blow fuses? Other issues?
OK, the voltage won't be exactly right. Can I remove a few turns to raise or lower the volts out?
