I think it has to do with most of the stuff we use running on ac. most Ups doesn't make a good enough replica of the sign wave that pumps etc are used to, and that can be bad for them. I'm sure someone else can explain it better. O think there are ones that are good to use but they are a lot more pricey.
To answer last first, no, what a server uses (DC - filtered through a transformer) is not anywhere near what a pump uses (AC - straight from the UPS).GDawson said:Coral reefer said:Ups is weird fir some stuff like pumps.

I was looking at UPS at Fry's for my return pump. My pump is 37 watts and the UPS will supply 40 watts of power for about 3 hours. During the summer this should be enough.
Given the quote above what sould I be looking at? Is there really a difference beteen the type of power a server would use vs a pump? Shouldn't the UPS be duplicating what comes out of the wall plug?

GreshamH said:Yes it will say it on the box, and in the price. True sine wave UPSs are not cheap, you won;t find one for $100. The unit I was looking at a few years ago ran ~$1,200
DO a search here for UPS, this has been covered in the past.
