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 DIN
rail.ï¿1Ž2 Because this site is on AC power 99.99% of
the time, it's not a big deal (to me) if it takes 24 or
even 48 hours to get a full charge.ï¿1Ž2 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.

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?
