For anyone interested, here's a 48VDC 25A supply. you'll probably
have to cut and paste the URL below, but they still sell them for 68
bucks..well made with fan and LED ampmeter.

It's called an MPR-25 and was a rack-mount for a battery charging
system.

Pictures of finished item can be seen here under Bloy's Stuff:

I'm using to run three gecko 320s and large servos...works good.
Just for fun, I modified it to include the filter cap, easy
connector for DC out in back and a 240VAC cord and plug. After
adding some enclosure metal over cap and back, I painted it. Nice
unit now.
