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

Tellabs stuff seems to work reasonably well: I've got a model 8001 -48VDC
PDU in my lab rack at home, although it only supplies @ 1A, it does a fine
enough job for what I need.
Have a look at the Tellabs PS-1478 or so, which should do 10A. They're
not explicitly rackmountable, but look like
I am using this:

Locally it is available here for about $50 USD as new. I found it in a shop
selling electronics for disco - don't tell them you are doing networks,
that info will multiply the price by 10 :-).

If you need to be able to charge a 48v battery plant you'd want the 60v version
instead, but it's more $. The 50v one works fine for benchtesting equipment,
at least.
