Back to transformers!
Would something like this work as an isolation transformer? It doesn't exactly
meet my requirements of being 120v/240v primary (switchable), but maybe 277v is
close enough to 220?

I am not sure I'm sending this correctly, but here goes.
I want to build a 120 volt DC source that can supply ~35 amps. I would like to
have the primary either 240 (typical) or 120 v AC. It doesn't have to be
regulated, but must be somewhat well filtered. My question is about
transformers, this type of transformer does not seem to be a common item. Has
anyone ever heard of a 240/120 primary 120 secondary at these high current
levels?
Why do I need to use a transformer in the first place, can I not simply rectify
and filter the two legs of the 240 without a transformer?
Thanks
