Eaton 9155/9355 UPS
Premium power performance
Double-conversion design for highest power protection
Unlike some other commercially available UPS technologies,
the double-conversion design used in the 9155/9355 completely
isolates output power from input power anomalies and delivers
100-percent conditioned, perfect sine wave output, regulating
both voltage and frequency. Even when presented with the most
severe power disturbances, power output remains stable.
Self-correction
If it senses a problem, the 9155/9355 instantly transfers the power
path to a bypass source with zero interruption in power. When the
alarm condition passes, the 9155/9355 automatically reverts from
bypass to normal power.
The 9155/9355 features a graphical LCD that provides useful information such as load status, events, measurements and settings.
The 9155/9355 continually monitors incoming electrical power and
removes all power irregularities that are inherent in commercial
utility power. During power outages and other interruptions, internal batteries provide emergency power to safeguard operation.
With the 9155/9355 UPS, data centre and facility managers can
rest assured that their systems and equipment are fully protected
from the effects of mains disturbances.

Self-diagnosis
The 9155/9355 constantly monitors its own operation – including
voltage, temperature and function of internal components – and
sends an alarm or takes action if it detects a potential problem.

Efficiency and cost savings
The 9155/9355 delivers a robust combination of low input current
distortion and high power factor for maximum efficiency. Operating
at greater than 90 percent efficiency across all load ranges, the
9155/9355 helps to reduce utility costs, extend battery runtimes
and produce cooler operating conditions.
In addition, Eaton´s use of sustainable materials and highly efficient manufacturing technology results in savings in carbon foot
print compared to competitive UPS products.
The 9155/9355 UPS provides industry-leading power density and a
10-40 percent footprint reduction versus comparable UPS solutions.
All standard 9155/9355 configurations incorporate internal batteries to provide significantly more runtime and offer 13 percent
more capacity at equivalent VA ratings. Extended runtime allows
the 9155/9355 to power this extra capacity for nearly four times
longer without requiring additional hardware, eliminating the need
for costly and space-consuming external battery cabinets.
Standard 10 kVA and 20 kVA capacity models can also be upgraded to 15 kVA and 30 kVA respectively, providing 50 percent more
power with no additional hardware and no increase in footprint.
The small footprint of the 9155/9355 enables easy space planning
for data centres and saves valuable floorspace.

True reliability
Powerware Hot Sync technology boosts power reliability
Eaton’s Hot Sync technology is designed for parallel redundant
N+1 systems to satisfy 24/7 applications. It can also be used in
parallel capacity systems to enable customers with ever-increasing
load demands to take advantages of the scalability benefits it
offers. Thanks to Hot Sync, up to four equivalent 9155/9355
modules can be paralleled for additional capacity or redundancy.
Accurate, equal load share is the number-one characteristic determining the integral quality and reliability of a parallel UPS system.
With Hot Sync technology this is achieved without the need for
communication between the UPSs, thus no single point of failure
is added when introducing parallel modules to a system. From
an operational and economical viewpoint, the achieved “close to
perfect” reliability brings clear savings in the long run, as every
downtime incident is costly and might lead to unpredictable consequences.
Hot Sync
no common logic
The benefits of Hot Sync:
– Erases single point of failure
– Systems are capable of paralleling for both redundancy and
capacity
– Ensures that each module is operating independently
– No added circuitry or components are required for standard UPS
to be switched in to operate in parallel
– A proven technology – thousands of systems are operating successfully around the world
ABM optimises battery performance and service life
The ABM technology used in the 9155/9355 UPS maximises the
health and service life of batteries:
– ABM technology uses a unique three-stage charging technique
that significantly extends battery service life and optimises
recharge time compared to traditional trickle charging
Battery voltage during one ABM charging cycle

Eaton 9155/9355 UPS
– 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
battery health and remaining lifetime, providing user notifications to guide preventive maintenance
Extensive configurability
Enhanced communication capabilities
The 9155/9355 UPS is equipped with a variety of standard communications features for network connectivity and remote management applications, including:
• RS-232 serial port
• Two X-Slot® communication bays
• Relay output contacts
• Two programmable signal inputs
• Remote emergency power-off (REPO)
ConnectUPS-X Web/SNMP
X-Slot card
Easy network connectivity and monitoring
ConnectUPS-X Web/SNMP card
The ConnectUPS-X Web/SNMP X-Slot card connects the
9155/9355 directly to an Ethernet network and the Internet and
enables graceful shutdown of multiple computers over the network. The ConnectUPS-X Web/SNMP also features a three-port
switching hub.
Environmental Monitoring Probe
Environmental Monitoring
Probe
The Environmental Monitoring Probe (EMP) works with the
9155/9355 and ConnectUPS-X card to remotely monitor the ambient temperature and relative humidity of the remote environment.
The EMP can also be configured to provide the status of two
additional contact devices such as smoke detectors or open-door
sensors.
Modbus® card
The Modbus card is an X-Slot device that allows continuous, realtime monitoring of the 9155/9355 through a Building Management
System (BMS) or industrial automation system.
Relay Interface cards
Relay interface card
The X-Slot relay interface card provides four programmable isolated dry contact Form-C relay outputs (default setting: utility failure,
low battery, UPS alarm/OK, on bypass) and one input.
NetWatch is a shutdown agent for the ConnectUPS Web/SNMP
card. It is a very compact piece of software, but still features powerful configuration options for shutdown actions, timings and user
notification.
LanSafe® is a network shutdown software product that currently supports up to 20 operating systems. It ensures controlled
sequential shutdown of the whole network across platforms in
case of a prolonged power failure. LanSafe allows the shutdown of
up to 64 computers protected by a single UPS.
LanSafe
Intelligent Power Manager is a software tool for managing networked UPS and PDU systems more easily and at lower cost than
the major NMS platforms, and is dedicated to power management
functions. Administrators have an overall, consolidated view of the
main operating parameters of all UPS systems. The web-based
interface is intuitive and easy to use, while also offering high configurability and powerful features.
Intelligent Power Manager centralises alarm management. It can
collate several events into a single message and deliver the message via email or SMS. Intelligent Power Manager is very easy and
fast to install. Once running, the software discovers manageable
power devices automatically and is operational in just a few seconds. A version of Intelligent Power Manager limited to 10 monitored devices is available free with each networked Eaton UPS.
