Eaton 9SX 

The Eaton 9SX constantly monitors
power conditions and regulates voltage and frequency.
The internal bypass allows service continuity in case of internal
fault, a maintenance bypass is also available (as option) for
easy replacement of the UPS without powering down critical
systems.
With a 0.9 power factor the 9SX delivers 28% more power than
UPS in its class. It powers more servers than other UPSs with
equivalent VA ratings and lower power factors.
Stronger, longer battery life: Eaton ABM® battery management
technology uses an innovative three-stage charging technique
that extends battery life by up to 50%. 9SX also provides
recommended replacement date for batteries.
