ML>  UPS == Uninterruptible Power Supply

ML>a Backup Power Source is something that /comes online/ only when power is
ML>beyond the upper or lower limits set in the device... eg: outtage, brownout,

ML>a UPS handles all of these but it is online all the time providing filtering

It is the industry that has blured the Meaning of UPS.
A TRUE UPS operates on the battery all of the time and needs no clicking
