Incredibly Intelligent
The Liebert Nfinity’s intelligent power system is the
key to higher availability and flexibility. 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.
IntelliControl
™
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
™
Modules — continuously monitor
the battery’s voltage, current, and temperature to
determine their condition and predict performance.
A built-in microprocessor in each battery module
provides the intelligence and communication
capability to allow the module to automatically
remove itself from the critical DC bus if necessary.
Intelligent Power Modules — ensure 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. Liebert 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 online system, Liebert Nfinity provides
continuous, regenerated sinewave output power.
Intelligent Bypass — provides seamless transfers to
and from the bypass source to insure continuity of
power and provide maximum system availability.
Higher Availability Flexibility
4-16kVA
12-20kVA
Shipped as a complete, fully tested
system, ready for final connection.
Hot-swappable modules allow
installation or replacement of
power, battery, control and display
modules without shutting down or
compromising power to the load.
Redundant components at critical
points of UPS operation.
Maintenance performed
without shutdown.
Intelligent, fault-tolerant design
enables the power, battery and
control modules to take
themselves “off-line” if there
is a problem, without
compromising system integrity.
Full self-diagnostic test is
performed when modules are
inserted and before going on-line.
Emergency power off capability.
Designed with N+x parallel
redundancy.
Patent pending intelligent
bypass technology provides
seamless transfers to and from
the bypass source.
Wide input voltage window
minimizes battery operation to
maximize battery life.
Generator compatible due to full
time output voltage and frequency
regulation.
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.
Scalable 4-16kVA & 12-20kVA
models available.
Customizable battery backup
times, due to a flexible frame
design that allows addition of
battery capacity without
increasing footprint.
Scalable design allows UPS
capacity or redundancy upgrades
without the expense or installation
downtime associated with the
purchase of a new UPS.
Additional battery cabinets can be
added for extended backup times
up to 72 hours.
Remote management and control
software enables greater control.
Lowest Total Cost Of Ownership
Longer battery lifetimes and fewer
battery replacements because
online technology minimizes
transfers to backup.
Modular batteries, controls and
power components help reduce
maintenance cost thanks to user-
serviceability.
Scalability allows you to cost-
effectively invest in added capacity
as it is needed.
Reduced installation time and
costs, because UPS units are
shipped with batteries connected
and charged.
