I'm sure you were smart enough to have Googled first, and having failed, asked
for help here. What makes you think we would have more luck in finding a url
with the required information than you have had?

What you are after is fairly specialised and in the realm of telecommunications
power supplies and you would be hard pressed to get any of the companies making
this sort of gear to make schematics available on the www. Unless you are
thoroughly experienced in building supplies of this power you could be wasting
an awful lot of money due to the emission of smoke. I always found it cheaper to
buy off the shelf when in need of a psu of this size - and you can always claim
on warranty if the thing blows up suddenly.

well I did find some schematics from a very helpful company rep

But it's not rocket science as I have discovered and am currently
using several large modified computer psu's

I manage, so again I ask do you have a schematic that you got with one
of those supplies you bought ?

a switched mode IC at your demanded voltage is hard to find , you will have to construct one with a transformer amd switched mode components like inductors , capacitors which is a headache , unless your application really demands efficiency , i suggest you to use a linear supply
