Hello!
Maybe this is FAQ, but could anyone advise UPS with standard AC output
but with main _DC_ (telco 48v) input?
Background idea is quite simple, equipment is situated at telco,
consists of Ciscos, computers, SRMs, all fed from AC, telco supplies
AC from invertor with bad quality (invertor has purpose of lamp feeding,
no demands to power quality), so the idea to eat directly from 48DC seems
tasty... ;)
Changing Ciscos to DC-variant is not an option, there is a lot of
other equipment, which is not manufactured in DC-variant.
Any advice (and/or URLs) would be gladly appreciated.
