Battery Times For The Prestige 3000 - Powerware Prestige 9 Series User Manual

3 x 200 WATTS x 1.4 = 840 VA
If the total load requirements of the equipment exceeds the capacity of
the UPS, you must either reduce the number of pieces of equipment, or
use a UPS with a larger load capacity.
When deciding on which pieces of equipment to remove from the UPS,
select equipment that has a lower priority for power protection.
Computers, monitors, and modems typically have a higher priority
because they could be processing or transmitting data when a power
outage occurs.

Battery Times for the Prestige 3000

During a power failure, the UPS battery supplies power to your
equipment, providing time to complete computing activities prior to
UPS shutdown. The duration of this time period is directly related to the
UPS battery configuration. By adding battery cabinets, you can
customize the UPS to provide enough battery time for normal processing
activities.
