With advances in miniaturization and processing power, a single
rack of equipment demands more power than ever—and more
equipment will be served by dual cord power supplies. It’s a chal-
lenge to provide power protection for expanding loads in shrink-
ing spaces.
Fortunately, technology advancements have also raised the den-
sity per square foot of power protection systems. The Powerware
9155 and new Powerware 9355 uninterruptible power systems
(UPSs) deliver premium levels of efficiency, reliability and flexibil-
ity—all in a sleek tower half the size of most competitor units on
the market today.
These double-conversion, online UPSs resolve all nine common
utility power problems and supply clean, continuous power to
all connected equipment. Even when presented with the most
severe power problems, power output remains stable. And if the
utility power goes out altogether, there is no delay transferring to
backup power.
These capabilities make the Powerware 9155 and Powerware
9355 ideal for protecting essential data center, communications
and electrical engineering infrastructures in corporate, telecom,
healthcare, banking, public sector and industrial applications.
Features
• Protects connected equipment from all nine of the most
common power problems with true online, double-conversion
topology
• Delivers maximum power density in a compact tower
design, only 12” wide and 33” deep, including batteries
• Provides more real wattage in less space with a 0.9 power
factor—protecting more equipment for every utility dollar,
and leaving more room for expansion
• Delivers extra capacity or redundancy through patented
Powerware Hot Sync
®
paralleling of multiple modules
• Significantly increases battery life through microprocessor-
controlled ABM
®
technology
• Provides 0.99 power factor and generator friendly <5% total
harmonic distortion using an active IGBT rectifier to control the
input power factor
• Ensures data and system integrity with complete power man
-
agement software for remote monitoring, management, and
shutdown
• Provides investment protection and peace of mind with an
Eaton factory limited warranty, technical support, and optional
service plans
