Negative Positive
Title: Disappointed with this UPS
Review: My edition of this UPS has been in operation for over two years, and all internal tests indicate operation well within defined parameters. During the past several months, there have been severe lightening storms in my area, and power has dropped out momentarily (~1sec) on three separate occasions. In EACH case, this unit has not snapped to battery power for at least 500 milliseconds, allowing the computer to crash. The unit behaves as if the relay that activates at power dropout is being substantially delayed. DISGUSTING!UPDATE: After posting the initial "sour-grapes" review, I continued research on my problem. When I built the current desktop computer, I incorporated a PFC power supply (phase correcting, to increase conversion efficiency), and literature available indicates this UPS may not be compatible with that type of power supply. I've already ordered a PFC-compatible UPS (Cyberpower), and will report on the results once it is in place.
Is the review positive or negative?
