Eaton Electrical Powerware Single-phase UPS 9155 - Manual (Page 4)

Powerware 9155 and Powerware 9355 UPSs also use sophisticated
technologies that maximize the health and service life of batteries:
• ABM technology uses a unique three-stage charging technique that
significantly extends battery service life and optimizes recharge
time, compared to traditional trickle charging.
• Temperature-compensated charging monitors battery temperature
and adjusts the charge rate accordingly, which properly charges
the battery and greatly extends battery life.
• An integrated battery management system tests and monitors bat-
tery health and remaining lifetime, and provides advance notifica-
tion to guide preventive maintenance.
Unlike heavy, old-style batteries, Eaton's are easily field-replaceable.
One person, working alone, can replace a battery without disrupting
data center operations or power to protected equipment.
Advanced design delivers unequaled power
performance.
The innovative design of these UPSs deliver the industry’s best per-
formance combination of efficiency, input current distortion, input
power factor, and output power factor.
Lower costs, lower temperatures. High efficiency (greater than 90
percent across all load ranges) reduces utility costs, extends battery
runtimes, and produces cooler operating conditions.
Generator-friendly design. Total input harmonic distortion (THD)
remains below five percent without compromising overall effi-
ciency. The result is maximum transfer of power between source
and protected load, and exceptional compatibility with auxiliary
generators.
More real power. On the output side, high power factor enables
these UPSs to provide their full power capability to modern IT
equipment that may have a wide range of leading and lagging
power factors. And, with a 0.99 input power factor, these UPSs
avoid the disturbances that energy converters tend to cause.
After 15 years of in-service experience, Eaton
has real-world proof that ABM technology
can significantly increase battery service life.
