[R-390] Isolation transformer questions

[Scott, Barry (Clyde B)]

Thanks to those who replied.  I figured this would be too simple and
probably would not work, but I thought I would ask.  Since I want to keep
all the smoke inside the transformer, I'll either stick to standard wiring
or get a bucking transformer setup if it becomes necessary.

Thanks again,

Subject: [R-390] Isolation transformer questions


Thanks to a list member, I'm the proud owner of a very nice isolation
transformer (Model DU-1 shown in the following page)

http://www.belfuse.com/Data/DBObject/pgs28_29.pdf

I'm wondering about connecting the secondaries.  Normally, I would connect
both 120V secondaries in parallel yielding the full 9A capacity; however, my
line voltage is a bit higher than I'd like.  I know I could use one
secondary and one of the other secondary windings to "buck" 6 or 10 volts,
but that would limit the current to only 4.5A.

My question is this: what would be the result of connecting the 120V
secondary in parallel with the 110V secondary of the other winding?  Is
there an "averaging" effect?  Will this damage the transformer?  I've never
thought about this before and wonder what will happen.

Thanks in advance,
