Confirming PSU spec for steppers.

Ahh, wait a second. Is the 625VA shared between the two outputs or per output?

Ok I see where your going wrong.? Nope forget the Va rating for now the only bit your interested in is the secondary outputs.

You have 2 and you can either have them separate so effectively making 2 completely separate PSU's or wire them together to make one large supply.
If wired in series then you add the voltages for each secondary together but keep the amps the same. Wire in Parallel then you do the opposite.

IE 625Va 2 x25V Can have this combination.?

1 x 25Vac x 12A = 1 x 35Vdc @12a PSU
1 x 25Vac x 12A = 1 x 35Vdc @12a PSU

OR
1 x 50Vac x 12A = 70Vdc @12A Psu = Wired series

Or
1x 25Vac x 24A = 35Vdc @ 24A Psu = Wired Parallel

I have a few more questions I shall need to read into I think. You've already been more than patient with me! Thank you both.
