Their Modular system is a couple thousand USD ......depending what
modules you get.
IDK what the setup from the PDF costs, but it looks pretty clean. If
you can afford a setup like that you won't regret having it.

Does anyone know what they consider 'affordable'? :)
I recall looking at their gear a while back. Seemed nice, but came with a hefty
price tag.
Cheers,

Subject: [AFMUG] Tower UPS's (again)
We've been using the APC SmartUPS 750XL as a Tower UPS for several years.
Put 2-8 100+AH AGM Batteries on them, and they've been rock solid for us. I
can think of only a handful of failures in the dozens deployed over the last
several years. I used to source them off ebay for $50-$70 each, but they're
becoming more and more scarce. Anybody have a recommendation for a simple UPS
that will do all the monitoring that the APC does and accept big batteries?
We're a Metro-Rural Area, our power outages are usually measured in Hours, not
days. So I'm not as concerned with the inefficiency of doing the DC/AC/DC
Conversion for Runtime, just power stability during
outages/fluctuations. I like the ease of connecting the external
batteries to the APC, since the XL line has an Anderson plug on the back for
them, and has a larger charger than the normal UPS, so recharge times are very
quick.
When the boss goes to the WISPA Shows, his head is filled with all kids of
ideas, so he want's me to investigate doing everything as a DC Plant, When I
price that out, with chargers, voltage converters (24/48), inverters, fuse
protection, LVD, Monitoring, etc, it always seems like the price is a couple
hundred dollars of parts and it would be cobbled together.
Am I missing something with doing a DC Plant? I see the telco's at the sites
using a rackmount rectifier with power supply modules, but those are a several
hundred by themselves, and they are only 48V, they don't have to worry about
24v radios. When I build a site now, I drop in 2 batteries, and the APC, and
the site is up and running in a couple minutes. A DIN rail with a couple power
supplies and the box is done, and has fully monitored power, and I can plug in
whatever I want without any equipment modifications.
