Prof95,
Thanks much for actually testing this and sharing your "time and work" with us as always.
Would units like a flat screen or computer on the output of an uninterruptible power supply (UPS) be safe from an overvoltage that the MOV does not protect against? Or would the UPS fail and just carry the overvoltage to the units?
Thanks,

There is a lot here I do not know. Therefore, I will stick to what I believe I do know.
I do not believe that new digital LCD or Plasma TV sets are any more prone to damage by an inconsistent electrical supply that older analog TV's. But, when we sink a couple of grand into a new 52" plasma set we become more concerned than we did with the older analog sets we could buy for a saw-buck or two.
My system is unique (free). I was fortunate enough to have an APC 1,000 UPS given to me by a friend when the OEM batteries died. I pulled the DC wires out the back, placed it on a shelf in my basement, connected two 12 volt batteries and plugged my plasma TV into the UPS via an extension cord. Just for good measure, I added a surplus Leviton Transient Voltage Surge Suppressor that was part of a discarded server. Based on APC’s product literature and my testing, I have come to believe it is an extremely effective method of protecting the TV from power irregularities. It should not pass on a spike or surge. I do not know if this is true for all UPS units built by someone other than APC. If one were to go out and purchase the APC UPS and Leviton unit new, it might be somewhat expensive.
Secondary to that, and still to be accomplished, is a good arrestor system for the dish, cable and antenna coaxial feeds. I will accomplish that before the Spring/Summer thunderstorms arrive.
Just to make the reply legal for the forum, the system also protects from a malfunction from my Chinese power back-up generator. Well, it would if the Chinese generator was friendly to the UPS, which it is not.
Just extra insurance…. sort of like an umbrella policy.
