Emerson Network Power Has A UPS
That Matches Your Growth Plans
Changing data centers, rapid and unpredictable
growth, plus a myriad of other power-related
challenges are making it increasingly difficult to
protect critical network equipment and other
electronic components.
As you upgrade and expand your business, do you find small UPS
proliferating throughout your racks? Do you lose track of how old each
UPS is and when the batteries should be replaced? Are dropped loads
your first indication that the UPS has a problem?
If this situation sounds familiar, then a data center UPS like the Liebert
NX can simplify your life by eliminating multiple points of failure, and
consolidating your power equipment into one professionally serviced
system. If your power requirements are changing faster than your UPS
can, there is a Liebert NX model that is perfect for your application.

Liebert NX Features
The Liebert NX family of UPS systems offers a variety of
operating features to meet a wide range of requirements:
Capacity Growth
n Parallel for capacity — Up to 3 UPS modules may
be used in a parallel configuration to provided
added capacity as needs grow.
n Parallel for redundancy — Up to 4 UPS modules
may be used in a parallel configuration to provide
redundancy for added reliability. Contact factory
for switchgear options when paralleling more than
4 UPS modules.
n Parallel unlike capacities — The Softscale
technology of the Liebert NX allows you to change
your growth increment without having to obsolete
your existing UPS. For example, a Softscale UPS
rated 80kVA can be paralleled with another
Softscale UPS rated 120kVA for a combined output
capacity of 200kVA.
n Optional paralleling cabinets — These cabinets
include various switchgear configurations to
parallel NX modules rated 20kVA or 30 kVA, or
Softscale models rated 40kVA – 200kVA, for
additional capacity and redundancy.
n Softscale
™
technology — The Liebert NX UPS
Softscale capability provides fast software
scalability. Purchase the capacity you need
today, then when your power needs grow you
simply purchase a software key and an Emerson
Customer Engineer will visit your site to increase
the UPS capacity. Softscale models are available in
the range of 40kVA to 80kVA; 80kVA to 120kVA,
and 160 & 200 kVA.
Advanced Electronics
n Digital signal processor controls — The
advanced topology of the Liebert NX features
a digital signal processor (DSP) controlled IGBT
rectifier and IGBT inverter. Digital controls provide
the fastest possible power management to
enhance reliability, accuracy and efficiency while
reducing component count.
n True on-line double conversion — Output power
is regenerated inside the UPS, providing protection
from the full range of power irregularities.
n Optimized Efficiency using
Soft-switching technology — This design
technique improves system efficiency and
maintains high efficiency performance from 40%
to 100% utilization.
n IGBT-based input power factor corrected
rectifier — Enables the Liebert NX to achieve its
impressive THD and PF performance.
n Dual bus synchronization — Provides the
capability to synchronize the outputs of two
independent UPS when they are configured
as a redundant system feeding independent
distribution paths.
Performance
n Eco-Mode high efficiency configuration —
Operating mode that switches the UPS to static
bypass during normal operation. When power
problems are detected the UPS automatically
switches back to double conversion mode.
n High overload protection — The system’s static
switch overload rating makes it capable of clearing
a 20 A branch circuit breaker. Handles 125% for
10 minutes, 150% for one minute and a 1000%
overload for 10 milliseconds.
n Built-in automatic bypass — Transfers the load
to bypass in the unlikely event that a fault occurs
in the UPS.
n Optional maintenance bypass
distribution cabinet — Provides complete
wrap-around maintenance bypass allowing UPS
to be powered down or taken out of service
without disconnecting power to the load.
n Optional internal batteries — Batteries can be
housed within the UPS itself in Liebert NX 10, 15,
20 and 30 kVA sizes.
n Optional external battery cabinets — Provide
added back-up capacity for extended runtimes.
n Triple-mode battery charger for fast battery
recharge — Three charging modes ensure
maximum battery availability:
•Constant current charging provides maximum
rated current to the battery until the voltage rises
to a pre-determined limit.
•Constant voltage charging allows the batteries
to recover the final percentage of recharge
capacity. A boost voltage is provided for a short
term to reduce the battery recharge interval.
•Float charging maintains the battery at the
recommend voltage.
Physical Characteristics
n In-The-Row form factor — Liebert NX 40-200 kVA
models are housed in IT rack style cabinets for easy
integration within equipment rows.
n Front access service — Allows easy servicing of
critical internal components.
n Front access installation — No need for side
access when installing UPS.
n Compact footprint — Requires less floor space,
leaving you with more room for other equipment.
Communications
n Liebert IntelliSlot
compatibility — Power communications available
through Liebert IntelliSlot Web Card LB and Liebert
MultiLink
n Multi-language LCD display — Large and
user-friendly LCD display provides operating
information in twelve languages.
n Liebert NX Softscale Service with Ntegrated
Monitoring — Advanced monitoring and network
security capabilities from the service business of
Emerson Network Power provide an integrated
approach to alarm management, predictive
maintenance and emergency service response.
Utilizes remote monitoring capabilities to
provide periodic equipment condition reports,
alarm retrieval and warehousing, escalation
management, and 7 x 24 emergency
service response.
n UPS Service with Ntegrated Monitoring —
Advanced monitoring and network security
capabilities from the service business of Emerson
Network Power provide an integrated approach to
alarm management, predictive maintenance and
emergency service response.
