consider a dead ups case, as a project case

With the recent nice post on a SSR case. I thought I'd post an idea I've used in the past. In the business I work for, we have replaced quite a few, old UPS. Some are totally dead. No lights, no nothing. So I gutted one out, leaving a nice two compartment case, with power cord, circuit breaker, and outlets. All three wire. I wired the outlets directly to the circuit breaker, and added two snap in three wire outlets from dead inverter. Each snap in outlet, goes to their own SSR, then to the circuit breaker. Also have a transformer protected by the circuit breaker. Only low voltage goes in and out of what was the battery compartment. In the battery compartment I put a sx48 proto board, with the sx key header facing out of the battery door. This was done for my lighthouse project.

Think Inside the box first and if that doesn't work..
Re-arrange what's inside the box then...
Think outside the BOX!

It is like a battery that keeps power to a computer (or other electronic device) when the electricity from the power company goes out... Most UPS's also have filters and surge suppressors to guard against spikes (like what can happen during a thunderstorm) or drops (like when all the lights in your house dim for a few seconds in the summertime when everyone is running their air conditioners).
As a side note, I removed an APC brand one, with external battery bank add on. It had a nice heavy, heavy duty dc cable with quick connector. Score! They were 50-70 pounds, and the main old one fell through the box, destroying the front panel. Bummer.
like anything, the electronics also fail. I haven't had the chance to troubleshoot. If it doesn't have any lights, it is dead. Replace it. The ups we deal with, are old, and used to power phone systems. It is usually termed not a wise decision to put new batteries, which costs a lot, in a old ups. It has to be reliable.
