It won't be cheap. You're into some pretty hefty amperage.

I just spent $20,000 on gear here at CNN to provide 400 amps of -48
vDC power from an AC source for some routers for CNN.com's network
connections.

You could try two of the PM24/35's in parallel to get the 50 amps.
Derate the 35amp continuous load by 10% for parallel
operation.http://www.newmarpower.com/powermodule/powermodule.html

You're also looking at needing a 40amp circuit for rectifying that
much DC amperage at that voltage.
