For large plants, the Sageon brand is excellent and for small scale, 48
VDC @ 30 amps the Argus brand is excellent. The Sageon units are
stand-alone. The Argus units are rm @ 19" and 23".
We use both.

We're using this a product by C&D and happy with it:
http://www.cdstandbypower.com/product/power_sys/system/sageon.html
Runs very quietly, very efficient (compared to what we used to have)
For our smaller sites, we use Valere:

It's amazing how compact they've made these units.

Who does everyone like for -48VDC power systems nowadays (say in the 60A
@48VDC and 600A@48VDC sizes). Something like you'd deploy in a POP or a
10-rack MMR with A&B.
Management/no-management, not a big deal.
Off-list is fine, and I'll be glad to summarize for the list.
Thanks in advance,
Deepak
