Had anybody ever heard of an uninterruptable power supply using SMPS technology?
I had a Philips branded one I got about 4 yrs ago, for an XP system, ran fine with my more recent 7 PC too, even though is small. rated like 300W. Today I decided to do a test on it, everything just died immediately. I investigated bad battery, software shoed 98% pre test, I looked at overload, it ran monitor, but not pc, I looked into changes in pc nothing that would cause overload. I took to bench to test, appears battery, and circuit are shot. I opened circuit part, I see a tiny charging transformer, and another about the size of the large transformer used in most PC PSUs. looked like switch mode, but I've never heard of that used on a UPS, and would think power factor correction most things use now would cause issues.
Never buying a Philips UPS again, 4 yrs isn't bad, but based on the design I want nothing to do with it. Has ports for phone/network surge suppression, on inspection all the lines are just linked no MOV's or nothing. So that was pretty much just a fake. Something like that makes me lose a ton of trust in some of these companies products. Now on pay more, and stick with APC or Eaton, maybe tripp-lite. I'm using a cyber power now I had laying around, I kind of expect that will end up like this Philips one.
Moral if getting a UPS don't buy like a $30 one. If ups is needed then like 70$ would be low as I'd go now, preferably 100ish. buy a cheapy you may just end up getting burned when it fails to do it's job, and destroys the stuff attached.
