Those are really expensive. A Traco TSP+BCM is several hundred less at
almost every wattage, last time I looked anyway. I like the split power
supply and battery module. A lot cheaper to replace a failed component
than an entire $700-1k all-in-one. But that's just me. The Traco gets
you temperature compensated charging and LVD. You get contacts for DC
input OK, batt OK/fail, etc. Hook that up to a SiteMonitor switch
closure module and you have pretty good remote visibility. Put shunts
wherever you want to monitor, battery charge/discharge current, output
rail current, etc.

Try these. We are about to install a couple of them. Some models
have ethernet ports for a GUI (no SNMP :-( ). But they do have
contacts to send alerts through a SiteMonitor (for example).

I'm at my end. I've been looking at this for a while now and it's
obvious that no one makes an industrial APC UPS that works.
We've tried the Alpha Cordex (DIN rail) and the ICT (19" rack) and
neither one can do what a APC management card can. We just need it
to provide 24vDC to a load and when the AC power goes out, send an
alert and let us monitor the system status via SNMP.
Alpha:
PROS: DIN rail mounted
CONS: Web interface is IE only, SNMP requests are completely
broken, have not tested SNMP traps, cost is about $700.
ICT:
PROS: It works well as a dumb power supply/charger with UPS
functionality, web interface works in all browsers.
CONS: SNMP is limited to about 6 values, all remote communication
is lost when AC is removed, no battery monitoring at all other
than the voltage for use with LV cutoff which is one of the values
that is not available via SNMP. Also costs about $700
I have to give it to Alpha at this point, at least their unit
remains "intelligent" when AC power is removed. If they would fix
their web interface and SNMP it would be perfect.
So... Does anyone have a solution that works that isn't completely
cobbled together? I need to know when we lose/regain AC power,
that the battery is draining, what the battery voltage is so that
I know when it's about to cut off, it needs a LV cut off to
protect the batteries, and all this information needs to be
available via SNMP and web. Am I asking for too much or does
something of this nature exist outside of TrippLite and APC?
