I just bought two
CyberPower 1500 UPS units from Amazon and so far, I'm really happy with them. One is dedicated to the iMac running WeatherCat and the display is set to sleep after one minute of being on UPS power. At that setting, the computer will run for over an hour. The second UPS has all the peripherals attached:
Raid Box,
Backup drive,
Meteobridge, Davis Console,
VoIP phone, Airport Extreme, and
network switch. It too, will run about 70 minutes. Even if the units are being overly optimistic about the times, even half of those times would be fantastic to get me through a typical city power outage.
I got a couple more smaller UPS units to run things like the water softener (if the power goes off during a regen cycle, the valve will stick open and dump hundreds of gallons of water down the drain) and the cable modem. Some ISP's power their network down stream even during a power outage, and some don't. If ours does, then the website and wunderground uploads will continue for around an hour. I feel better about having all this stuff protected and powered, but this pretty much means we won't ever lose power again . . .
