[R-390] Isolation Transformer

Wed, 22 Oct 2003 14:38:10 -0500

I thought 120/240 : 120/240 meant that I could select 120 or 240 on the
input and either one for the output.  Is this incorrect?  In other words, if
I use 120 as the input, then am I forced to use 240 for the output and
vice-versa?

Thanks,

The first one looks like it would work well.
For the second one you need 220 VAC for it to be useful as a 110 VAC source
but otherwise should be OK.

Getting an oversize transformer is always desirable as they will run hot if
used at their full capacity for extended periods of time.
