I remember when booking hotel rooms in Wash. DC being told to always ask for
the government rate, without actually saying you were a government employee.
I wonder if you could just ask vendors for the JAB price.

Crap, how well equipped is that? That's beyond even what you can get a
reasonably decked out Eltek Minipack shelf for these days, not seeing how they
could be worth that much. Must be mainly targeting those using OPM.

Yeah, saw them on Newmar. Usually "call for a quote" is a bad sign. I
hear that these are what Jab has standardized on. They seem pretty robust. I
imagine they come with free sticker shock.

We just got a couple of the 24V versions and it was only $300
each.ï¿1Ž2 About the same as the Traco for the two separate units.ï¿1Ž2 I sure
appreciate the differences, but I was looking for extra-small form factor on a

IIRC, these units also have LVD.

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.

Some models have ethernet ports for a GUI (no SNMP :-( ).ï¿1Ž2 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?
