Powerware 5140 Features
Load Segments
Load Segments are groups of receptacles that can be independently controlled via the front panel LCD interface and/or LanSafe III/FailSafe III, which is bundled with the Powerware 5140. Load Segments provide extended battery run times and flexible management of the UPS. The five Load Segments of model PW5140 6000i are outlined below.
Load Segments divide the Powerware 5140 into five virtual UPSs
Shut down Load Segments to decrease load and extend backup time for other Load Segments

Unity Power
Factor Rating
What does unity power factor rating mean? Quite simply, it means that the watt rating of the UPS is equal to its VA rating. Traditionally, UPSs have been designed, built, and sold with a power factor rating of approximately 0.6 to 0.7. For example, a 1000 VA UPS could supply a maximum of 600 to 700 watts. Historically, this
0.7power factor was appropriate for the majority of computer loads the UPS was intended to support since most computers demanded power at a 0.7 power factor.
Today, however, a large percentage of

To support this load, you need to select a UPS with a rating that meets or exceeds both the watt and VA demand shown above.
A traditionally rated 5000 VA/3750 watt UPS without a unity power factor rating cannot be used. The Powerware 5140, on the other hand, has capacity to spare.
