Can anyone recommend a good isolation transformer for sale on-line?
Need one that will handle 5 amps or so at 120VAC, and have a standard AC
plug at the outlet. Prefer one for less than $100 or so, unless that seems
unreasonable. Found one at Mouser for $114 but that's only good for 1.25A.
Getting lots of irrelevant hits on google...

Thanks.


I think the $100 and "good quality" exclude each other for a transformer
that size.

the smaller units as used with cash registers and POS systems tend to max
out at 4 amps.

is used is ok, look for stuff from acme, topaz, oneac, shape, powervar.
powervar even had some interesting ones based off toroidal tranformers if
you want the ooh and aah factor.


Not cheap. Surplus Sales of Nebraska has some.

Depending on what your going to do, check if it has the secondary to ground bonding
which you should remove if you are seaking ground isolation.
