Transformer source needed

Does anyone have a source for custom PC mount transformers that they can
share?
I need to convert a 7805 based 5V supply from a 230VAC line to 277V and 230V
'standard' transformer primaries are only OK'd for use 10% above their rated
voltage. I am hoping to be able to have a few specials wound, but I need a
source.....anyone, please?
TIA,
Chris

Look into Buck-Boost transformers.
They're designed for exactly that

Can you go into a bit more detail?
There are some sneaky ways that you could work around the problem, but it
would be useful to know what you are trying to achieve.

The 277 voltage is standard lighting voltage in a 3 phase 480 VAC power
supplied factory. Lighting / power transformers from an industrial
electrical supply house should have as many of these as you need, as
this is a common problem.
