I dis(re)member how much current you need, but recycling (surplus) is
probably a good option as well:

and a host of others. A decent range of cost and reliability options.
Derating  and cooling are the real reliability enhancers in decently
designed supplies.

And, this was designed for a telecom application, so it's /probably
/rated for 36-72 VDC. This is the normal specd range for 48 V nominal. 
I'd still use a 48 V supply, but would be too concerned about regulation.
