Double conversion UPS
Premium power performance
• Double conversion topology provides the highest level of
protection available by isolating the output power from all
input anomalies.
• With a transformer-free design and sophisticated sensing
and control circuitry the 9155/9355 delivers an efficiency of
up to 92%.
• Active power factor correction (PFC) provides unbeatable
0,99 input power factor and less than 4,5% ITHD, thus elimi-
nating interference with other critical equipment in the same
electrical network and enhancing compatibility with genera-
tors.
• With 0.9 output power factor, UPS is optimized to protect
modern IT equipment without need to oversize.
True reliability
• Hot Sync technology enables paralleling of two or more UPS
modules to increase availability or add capacity. The technol-
ogy enables load sharing without any communication line,
thus eliminating single point of failure.
• ABM technology charges batteries only when necessary,
reducing batteries corrosion and prolonging batteries service
life by up to 50%.
• Internal batteries in all standard configurations provide an
extended runtime with the smallest footprint.
Extensive configurability
• Further runtime extension is possible with external battery
cabinets.
• A multilingual graphical LCD display makes possible to moni-
tor the UPS status easily.
• The 9155/9355 can also be integrated into network manage-
ment, industrial automation and building management sys-
tems.
• Bundled Eaton Software Suite provides an orderly network
shutdown in an event of extended power outage.
Cost savings and sustainability
• The 9155/9355 features high up to 92% efficiency, thus
reducing utility costs, extending battery runtimes and pro-
ducing cooler operating conditions.
• Compact space efficient tower design offers smaller foot-
print enabling easy data centre space-planning and preserv-
ing valuable raised-floor real estate.
• Included internal batteries eliminate the need for costly and
space-consuming external battery cabinets.
• A single technical platform used in Eaton´s three-phase UPS
products guarantee easy upgrades and similarity in service,
thus lowering total cost of ownership.
• A range of service agreement options can be easily custom-
ized for customers’ needs and budget.
• Eaton uses sustainable materials and highly efficient manu-
facturing technology, thus generating dramatic savings in
carbon footprint as compared to competitive UPS systems.
