Posted by: silentnights at Thu Oct 11 19:06:45 2007 [ Email Message ] [ Show All Posts by silentnights ] I don't know the conversion formula but an ups is rated at VA (volt-ampres). So if you know how many VA's your heating uses per second, then you could plan on how long your ups would last. Lets say you buy a $50 600 VA ups, and your heating uses .0002 VA/s. That means your ups would last 833 hours ((600/.0002)/3600(seconds per hour)). Figure out your average VA and you are golden. Calling Zoo Med, they should be back with me momentarily and hopefully they can give me the VA information necessary to do the math. Or maybe I've got it completely wrong. Probably so, it looks like they have a max wattage, and a number used for the number of hours. Zoo Med's heat cables come in ranges from 15 watts to 100 watts. So your pull is still about 1/4th that of a computer monitor. So it would probably run for about an hour for a 100 watt heat cable. | ||
