Greetings NANOG'ers!

I have a small home lab which I mostly use for learning and testing.  I'm
likely to receive some gear that needs negative 48VDC (ie: positive
ground).  Mains is a typical 120VAC, 60Hz.

Can anyone recommend a power supply, reasonably priced, to go from 120VAC
down to -48VDC@10Amps?  Something that fits in a two post rack would be
preferred, but not required.

Thanks,
Mark


Mark,

I'd recommend a Kepco PRR 48-22M.  We have one in-office, used it for
some -48VDC equipment (Adtran Total Access gear) that we tested
in-office.  Worked great, and can be found on eBay for under $400
