Because we have lots of power failures where I live, I bought a UPS as I understood that if you run your computer through it, you'll get a constant supply of smooth power, so when there's a power failure, you'll at least have a few minutes to save your work and close your computer down properly.
But this UPS switches off and on for just a fraction of a second when there's a power failure - just enough for me to lose my modem connection and for my computer to turn off and start rebooting. I thought's wrong so I took the UPS back to the store, they supposedly sent it for repairs, but now it's back and I think it's the same as it was. I'm hesitant to test it on my computer, so I tested it with an ordinary 60 watt reading lamp. I first charged the UPS overnight, and now if I simulate a power failure by turning off the switch at the wall, the reading lamp flicks off and on for just a second before it starts running on the UPS.
Is the UPS faulty, or is this really the way it works?
