The digital lifeblood of
many organizations -- computers, servers, phones, datacom links -- now
resides on networks...outside of the traditional "glass house" protection.
This may make companies more flexible and responsive, but it also makes them
far more vulnerable to power problems, and the threat of catastrophic losses
in sales, customers, productivity...your business lifeblood.
The
solution is a UPS designed like never before
Now for the first time,
your can achieve the highest levels of UPS reliability in a system that is
sized to protect network applications. The Liebert Nfinity UPS is designed
for use with workstations, servers, networks, telecommunications equipment
or other sensitive electronics. It provides continuous, high-quality AC
power to your mission-critical systems, protecting them from any power
aberrations due to blackouts, brownouts, surges or noise interference.
Power protection
The Nfinity power system
is a scalable 4 to 18 kVA UPS, designed with N+x parallel redundancy to
provide a fault-tolerant network of power protection for maximum systems
availability. Its modular design makes Nfinity the most adaptable UPS on the
market, offering easy upgrades and servicing. |

 |
 |
 |
 |
|
| |
"High nines"
reliability means 99.99999% system availability. In practical terms, that
means "zero downtime" for mission-critical applications.
Each of these five reliability needs must be met individually, and the
entire protection plan must integrate faultlessly. It requires a new level
of protection planning, and a dedication to seamless execution.

Nfinity's modular design
was devised to provide easy scalability to users as their power demands grow. By
simply installing additional power or battery modules, you can expand your
current system, extend your backup runtime or add redundancy.
Scalability Provides The Flexibility To Expand
Nfinity's patent-pending
frame design provides the user with the maximum adaptability that is demanded in
todayŐs ever-changing network environment.
Because Nfinity is scalable for redundancy, power capacity or battery run time,
you have greater flexibility in how you can use the system. Configurations can
be cost-effectively upgraded without re-investing in a new system or
installation.
Longer
Battery Run Time
The system's flexible
frame design allows battery backup times to be customized to customer needs
while maintaining a smaller footprint. To extend run times, just add battery
modules. Nfinity also has a faster recharge time than similar units.
12-Bay
And 8-Bay Models Available
Using an 8-bay frame,
Nfinity provides capacities up to 16 kVA in a non-redundant mode and up to 12
kVA in an N+1 redundant mode -- with an incredibly small footprint (only 20"W x
28"D x 41"H). In an 8-bay frame, power modules must only be used in the top half
of the frame with a maximum of four modules. Up to seven battery modules can be
installed in any of the bays.
The 12-bay frame provides
up to 18 kVA, with or without redundancy, in the same footprint as the 8-bay
unit and only 54" high. An 18 kVA system will actually have 20 kVA of power
capacity, however, the actual output power is limited to 18 kVA to allow direct
connection to a 100A feeder. The 12-bay frame can utilize up to six power
modules in the top half of the frame and as many as 11 battery modules installed
in any of the bays.

Nfinity is the most
intelligent power system we've ever built. The fault-tolerant design enables
the power, battery and control modules to take themselves "off-line" if
there is a problem, without compromising system integrity. System level and
individual module microprocessor controls increase UPS functionality and
reliability. When Nfinity modules are inserted, they perform a full
self-diagnostic test before going on-line.
IntelliControl™
Module -- The system control module works with the user interface to
provide vital information about the condition of the power and battery
modules. The use of a paired system control provides full systems
functionality in the event of any single failure and ensures that operations
and communications are always available.
IntelliBattery™
Module -- Nfinity's patent pending innovative battery module
continuously monitors the battery's voltage, current, and temperature to
determine the state of its batteries and predict performance. Each module
contains an intelligent battery sensing circuit that will take it off-line
if a problem is detected, so as not to affect the performance of other good
battery modules in the system. |
|
 |
 |
Intelligent Power Modules -- provide protection against power outages,
spikes, surges, noise, and sags. Designed in 4 kVA "building blocks," they
utilize patent pending current sharing technology that ensures premium
quality power. Nfinity power modules feature a power factor corrected (PFC)
rectifier to create a sinusoidal input current waveform. This allows the
system to use utility power more efficiently and reduces reflected
distortion. A true on-line system, Nfinity provides continuous, regenerated
sinewave output power.
Intelligent Bypass
-- The patent pending Intelligent Bypass technology provides seamless
transfers to and from the bypass source to insure continuity of power and
provide maximum system availability. |

status.
Relay contact cards to provide contact closures for remote monitoring of
alarm conditions.
The system also communicates to and monitors internal and extended
battery cabinets.
|
|
Shutdown Monitoring Software
MultiLink™ is the perfect
complement to the Liebert Nfinity UPS because it prevents unexpected server
shutdowns, protects data and minimizes downtime. The software provides
unattended, orderly shutdown for one computer or many, and is especially
effective with large server farms. MultiLink has full event management and
displays UPS instrumentation on screen. MultiLink is available for all
popular operating systems and can be downloaded from the Liebert website at
www.liebert.com. |
User
Interface Control Panel
The user interface is the
main source of communication between the Nfinity UPS and the user. It features
an easy-to-read LCD display and LED mimic diagram. The control panel informs the
user of the status of the UPS, including the power and battery modules, and
allows you to configure the system to fit specific needs or preferences. You can
also review the event log and even receive instructions on replacing modules.
| |
 |
 |
|
| |
The
modular design of Nfinity allows you to choose the amount of redundancy you
need with greater flexibility than competitive systems. When in a redundant
configuration, a failed module will automatically take itself off-line while
the other modules continue to support the connected equipment.
