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

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

Putting It All Together:

The Liebert Nfinity UPS System

The Liebert Nfinity power system is ascalable UPS utilizing fault-toleranttechnology in two scalable models: 4 to 16 kVA and 12 to 20 kVA. Designedwith N+x parallel redundancy capability,its modular design was devised toprovide easy scalability to users as theirpower demands grow. Configurationscan be cost-effectively upgradedwithout re-investing in a new system orinstallation. The patent pending framedesign houses all of the modular systemcomponents, including 4 kVA powermodules, battery modules and system control modules.

Liebert Nfinity is the perfect power protection solution for:

Cabinet Stands Small, Stays Small

Liebert Nfinity’s compact,efficient design allows you topack more power and batterycapability into a much smallersized unit, so it takes up less ofyour valuable floor space.

Higher Availability AndFlexibility Start With Higher IntelligenceThe 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 WindowA 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 CompatibleFull 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 CapabilityLiebert 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 ProgramLiebert’s two-year warranty provides for repair or

replacement of your Liebert Nfinity UPS during the

initial warranty period.

There’s A Liebert Nfinity Configuration For Your Application

The system control moduleprovides communications andcontrol for the unit.

The system utilizesindependent 4 kVA powermodules. Up to six powermodules can be operating at one time.

Each battery moduleis composed of ten individual12-volt batteries encased in aplastic housing.

Power and battery modulesare housed in identical bayswithin the frame. Powermodules must be contained inthe top half of the frame, whilebattery modules can beutilized in any of the bays. This allows battery backuptimes to be configured tocustomer needs.

Your Liebert Nfinity UPS can be ordered in dozens of different power and

battery capacities — and then upgraded at any later time as needs change.

Using an 8 Bay, 16 kVA frame, Liebert Nfinity provides capacities up to16 kVA in a non-redundant mode and up to 12 kVA in an N+1redundant mode — with an incredibly small footprint (only 20”W x 28”D x 41”H). The 12 bay, 16 kVA frame provides capacities up to 16 kVA in an N+1 redundant mode.The 12 bay, 20 kVA frame provides capacities up to 20 kVA in an N+1 redundant mode (both in only 20”W x 28”D x 54”H).

Incredibly IntelligentThe Liebert Nfinity’s intelligent power system is thekey to higher availability and flexibility. The fault-tolerant design enables the power, battery andcontrol modules to take themselves “off-line” if thereis a problem, without compromising system integrity.System level and individual module microprocessorcontrols increase UPS functionality and reliability.

IntelliControl™ Module — works with the userinterface to provide vital information about thecondition of the power and battery modules. The use of a paired system control provides fullsystems functionality in the event of any single failure and ensures that operations andcommunications are always available.

IntelliBattery™ Modules — continuously monitor the battery’s voltage, current, and temperature todetermine their condition and predict performance. A built-in microprocessor in each battery moduleprovides the intelligence and communicationcapability to allow the module to automaticallyremove itself from the critical DC bus if necessary.

Intelligent Power Modules — ensure protectionagainst power outages, spikes, surges, noise, andsags. Designed in 4 kVA “building blocks,” they utilizepatent pending current sharing technology thatensures premium quality power. Liebert Nfinitypower modules feature a power factor corrected(PFC) rectifier to create a sinusoidal input currentwaveform. This allows the system to use utility powermore efficiently and reduces reflected distortion. A true online system, Liebert Nfinity providescontinuous, regenerated sinewave output power.

Intelligent Bypass — provides seamless transfers toand from the bypass source to insure continuity ofpower and provide maximum system availability.
