PowerGuardian monitors a connected UPS (uninteruptable power supply) and if the power event is sustained, safely shuts down your computer, even saving your open files and work-in-progress.

PowerGuardian works with UPS's from most popular manufacturers (Belkin, APC, Powerware, Best Power, Tripplite, CyberPower, BlackOut Buster).

With the addition of a USB-to-Serial Converter from Keyspan, PowerGuardian will work with a wide range of serial UPS products; you are no longer restricted to the few models that support USB.

Sadly the website of product and the download link is defunct. From another site's comments, I think the developer gave up releasing (and selling) the product just because Tiger (10.4) added completely basic, only compatible with APC support for UPS. That is not a good reason to give up your releases, if that basic functionality was enough, Megatec and UNIX "nut" wouldn't be around.

Anyway, dead link, dead product. I also noticed this software name dates back as early as NeXT.

Very good software app.

tech support answered my emails within 30 mins.

running it on an Xserve which is connected to a APC Smart-UPS 2200VA RM via a serial cable.

if you have an UPS this software is a must have...

Great software! Works as advertised-and on a UPS (presently) listed as unsupported. Developers are FAST to get back to you. Definitely worth the $20.
