At any rate, I want to use this transformer in a DC
power supply. I have
three sets of windings: two sets are 120/240v "universal" series/parallel
type and the third is 24-0-24v center-tapped.
I want to run this from 120vac.
Is there any benefit to paralleling the two sets of 120/240v main windings
(i.e. 4 120v windings in parallel)? Will it increase the power rating of
the unit or is that mostly a function of the secondary winding?
In a lot of cases, the limiting factor is the primary winding (often when
a transformer burns out it's the primary the fails). So yes, I would
paralelle up both sets of windings. Is there a reason not to?
Suppose instead of 24-0-24 on the secondary, I'd like 12-0-12. Obviously,
one way to get this is to hook the primary (-ies) up as 240v. Is there any
benefit to be gained in parallelling the two 240v primaries?
Again, is there a reason no to?
