Mean Well AD-155B
or
Mean Well SDR-240-24 + DR-UPS40
or
Mean Well SDR-240-24 (or 48) + Traco BCMU360 (jumper selectable for 24
or 48) - I use this combo most often. The BCMU360 is only good for ~240W
continuous.
All this stuff is fine until you start looking to deploy things that are
power hungry like 450m's @ 70W, LTE eNB's that pull 60-100W each,
multiple AF24s or licensed radios, etc. Then you need big-boy
rectifiers, which aren't all that expensive, but they aren't cheap
either. Add good telco-grade batteries on top and it's easily 10x the
cost of what we're used to with the smaller stuff.

What is everyone using for switching from AC to battery backup at sites?
I normally have our other guy take care of that part. But we normally
have a DIN mount 24V power supply, a DIN mount packetflux site monitor
that monitors power supply output and battery voltage and some DIN
mount module that does charging and switching between the two. Also
have a 24V to 48V converter to power our 450i etc stuff.
Monitor the site monitor with SNMP and start emailing alarms if power
supply voltage drops. Also graph power supply and battery voltage
with MRTG.
Curious what others are using here?
