Uninterruptible Power Supplies for Supervisory Controllers


Any of you have recommendations or specs on UPS’s to protect Supervisory Engines? We lost 2 NAE’s and 2 JACE’s due to brownouts in our school district:eek2:. I put in Tripp-Lite UPS’s afterword, but I’ve been reading up a little on AVR (Automatic Voltage Regulation) on some UPS’s and bought one for my own home computer at a real decent price.

I need to spec these out for our school district. Any experiences with these out there for this application?
