You Depend On Your Network More Than Ever

IT managers are experiencing more change and uncertainty today than at any time in

the last 20 years. Network technology is advancing faster than your infrastructure

support strategy. It’s no longer just about managing system availability and growth;

it’s also about managing uncertainty, equipment density and capacity.

Smaller Rooms, Bigger Challenges

If you operate a small data center (up to 25 racks) or network closet, you
undoubtedly realize the importance of these critical IT facilities to your
operations. You will have to do more to protect the operation of your critical
networks in order to maintain business continuity. As servers and other
components shrink in size, capacity and criticality are increasing.

Powering all of this equipment is no small task. That’s why
Liebert has developed a power protection solution that
can expand easily as your needs grow.

Putting It All Together:
The Liebert Nfinity UPS System

The Liebert Nfinity power system is a
scalable UPS utilizing fault-tolerant
technology in two scalable models:
4 to 16 kVA and 12 to 20 kVA. Designed
with N+x parallel redundancy capability,
its modular design was devised to
provide easy scalability to users as their
power demands grow. Configurations
can be cost-effectively upgraded
without re-investing in a new system or
installation. The patent pending frame
design houses all of the modular system
components, including 4 kVA power
modules, battery modules and system
control modules.

Liebert Nfinity is the perfect power
protection solution for:

Small Data Centers
Network Closets

Liebert Adaptive Solutions
For Today’s Computers

The Liebert Nfinity is part of the
Liebert Adaptive Architecture — a
combination of power, cooling and
monitoring technologies that
provide mission-critical IT support
across your entire enterprise. The
Liebert Adaptive Architecture
delivers higher performance with
greater flexibility than any other
infrastructure design.

Higher Availability

Proven mission-critical
technologies that minimize single
points of failure produce the
highest possible availability of your
IT systems. With the Liebert
Adaptive Architecture, mission­critical technologies aren’t
limited to the data center — they
extend wherever you have mission­critical equipment.

Flexibility

The components of the Liebert
Adaptive Architecture can be
reconfigured to meet the demands
of new technologies, achieve
higher tiers of availability or
support increased densities — with
minimal disruption to operations.

Lowest Total Cost of
Ownership

Liebert technologies are designed
to minimize capital equipment
expenses and optimize efficiency.
Their ability to adapt to change
prevents obsolescence and extends
their useful life.

“The Liebert UPS systems were absolutely
perfect. We’ve not had any battery
problems with the Liebert systems and we
used to have that all the time.”

Cabinet Stands Small,
Stays Small

Liebert Nfinity’s compact,
efficient design allows you to
pack more power and battery
capability into a much smaller
sized unit, so it takes up less of
your valuable floor space.

Higher Availability And
Flexibility Start With
Higher Intelligence

The Liebert Nfinity is a true on-line,

double-conversion UPS that delivers

100% power conditioning, zero

transfer time to battery, no change

in output voltage and better

transient suppression than line-

interactive units. Built-in intelligence

is provided by system level and

individual module microprocessor

controls which increase UPS

functionality, communications and

reliability. The Liebert Nfinity also

offers added reliability with internal

bypass and optional redundant

monitoring.

Liebert Nfinity’s modularity and scalability allow you to specify a system that is right for your needs

today — but has the ability to expand with your requirements for the future.

Wider Input Voltage Window

A wider, variable input voltage range minimizes

transfer to battery to increase battery life. For lighter

loads, low line transfer can range down to 110V.

Generator Compatible

Full time output voltage and frequency

regulation is provided — a necessity for sensitive

electronic equipment and a must for sites with

back up generators.

Highest Overload Capability

Liebert Nfinity offers the highest overload capability

of any system in its class — capable of sustaining

110% of the system’s rated load for an extended

period of time.

Two-Year Factory Warranty Program

Liebert’s two-year warranty provides for repair or

replacement of your Liebert Nfinity UPS during the

initial warranty period.
