The Liebert NX has been designed from
the ground up to meet the power
protection needs of today’s sensitive
electronics. It combines reliability,
efficiency and value in a compact package
that is ideal for today’s applications. It is
simply the best investment you can make
in a medium size UPS system. Here’s why.
High Availability Of Quality Power
• The Liebert NX features built-in
reliability with a redundant power
supply card, redundant cooling fans
and highly efficient cooling of
critical components.
•Wider input voltage and frequency
tolerances contribute to high
power availability.
• Digital controls provide the fastest
possible power management to
enhance reliability, accuracy and
efficiency while reducing
component count.
• Dual bus compatibility and system
redundancy further enhance the
availability of power.
• The system’s static switch overload
rating makes it capable of clearing
a 20 A branch circuit breaker.
• High overload protection handles 125%
for 10 minutes,150% for one minute and
a 1000% overload for 10 milliseconds.
Reduced Cost of Ownership
• The improved input power factor
of the Liebert NX can actually reduce
your electricity usage.
• It delivers the highest possible input
power factor — greater than 0.99 at
rated linear and non-linear loads —
for maximum efficiency.
• The unique ability of the Liebert NX to
adjust power walk-in from 5 seconds to
30 seconds, along with reduced input
current distortion and power factor
correction, also enables you to save
money by reducing back-up generator
sizing requirement.
• The unit’s compact footprint requires
less floorspace, leaving you with more
room for other equipment.
Upstream Green Power
• The Liebert NX provides the cleanest
level of upstream power with the lowest
level of input current THD (total
harmonic distortion) in the industry.
• This ensures that clean power flows
upstream, avoiding damage to other
loads connected to the upstream power
distribution bus.
Ease And Simplicity In Scalability And Redundancy
• Two Liebert NX modules may be
paralleled in a redundant configuration
for added reliability and serviceability.
• The Liebert NX is compatible with
Liebert ’s unique dual bus
synchronization system.
Protection Of Your UPS Investment
• A wider input voltage window of +10 to
-20% and a frequency tolerance of 40Hz
to 72Hz provide high quality power,
even when input power is below
standard. This helps to minimize
transfer to battery, reducing the
charging and discharging cycles.
• Temperature-compensated battery
charging extends battery life.
• Back-feed protection ensures
system integrity.
• Short-circuit-proof, Active Star™
controlled inverter provides highest
output power quality.
Maintainability
• For safe and convenient servicing of the
UPS, the Liebert NX includes a built-in
maintenance bypass, optional wraparound
maintenance bypass with IP
20 UPS enclosure protection — even
with the front doors open.
• Use of a redundant configuration allows
you to utilize one module while the
other is being serviced.
• Dual bus compatibility enables you to
transfer the load to an alternate power
source for maintenance activities.
Serviceability
• The Liebert NX features easy access for
service thanks to front accessibility of
critical components, self-diagnostics
and various monitoring options.
System Flexibility
• Flexibility is achieved through many
choices including type of battery,
number of single and multi-unit
configurations, and an array of
internal and external power and
communication options.
• Auto restart capability provides
added availability.
• Ultra-quiet performance with noise
levels below 54dB allows greater
latitude in where to place the unit.
User Flexibility
• Large and user-friendly LCD display
provides operating information in
twelve different languages.
• Adjustable power walk-in, numerous
user-specified settings, a choice of
power monitoring communications
alternatives and user friendly control are
all handled through the menu-driven
LCD control panel with detailed data
reporting.
Power Communications
• To meet a variety of needs, the
Liebert NX can provide power
communications through a Relay
Contact Card, OpenComms™ Web Card
and MultiLink™ shutdown software.
