Tessco has them in the $2k range Gino A. Villarini @gvillarini

I hear that these are what Jab has standardized on. They seem pretty robust. I imagine they come with free sticker shock.

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. On 1/6/2015 10:49 AM, Bill Prince wrote: Try these.ï¿1Ž2 We are about to install a couple of them.ï¿1Ž2 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). http://www.altechcorp.com/power/CBI-UPS.html On Tue, Jan 6, 2015 at 8:23 AM, Christopher Tyler <[email protected]<mailto:[email protected]>> wrote: 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? -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107<tel:417.851.1107> -- -- bp part15sbs{at}gmail{dot}com
