Which is better, a UPS or an AVR?

[Long Silog]

Please name the pros and cons of each. Also I read that you can plug a UPS on an AVR. Is it possible and does it have more advantages? I'm asking these questions because my Sassin 1500VA AVR suddenly turned off, well not really turned off but the graph thingy turned 0 like there was nothing plugged in it.

AVRs don't have a battery in them UPS do as well many UPS have AVR circuitry built into them.

A UPS is what you want for a computer, so if there is a power loss you don't suddenly drop your system and possibly lose your data.

It really depends on how unstable you day to day power is. This is different from it being completely not available. The AVR main purpose is to correct for power fluctuation that are happening on a fairly constant basis. The UPS is mostly used for power that is either completely off or so far out of standard that it is unusable....for example extremely low voltage.

Now there are high end UPS that always are on, they take the power from the source and covert it to DC power and then convert it back to clean AC power. These are the ultimate solution to bad power but come at a price above what most people will pay.
