Better still, cast around on the surplus market for a power supply

I've spent time looking for large power suppliers with no joy. The
problem is a "snow storm" of offers with nothing the right voltage and
amps. I'm mostly looking eBay here, no way I've found to filter. I
would rather just buy this and let somebody else do the proper
engineering design.

Yup. Unless you're dealing with fairly standard voltages like 5V, 12V,
and 48V, it can be hard to get just what you want.

Power supplies are too easy to design to make it economical to force
users into a "one size fits all" design.
