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?
