Emerson Liebert NXE 20kVA NXF00203 User Manual

• The Liebert NX gives you built-in reliability

with redundant power supply cards,
highly efficient stratified cooling 
of critical components and optional 
redundant cooling fans.

• 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.

• High overload protection handles 110%

overload for 60 minutes, 125% for 10
minutes, and 150% for 1 minute.

• 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 maxi-
mum 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 cor-
rection, also enables you to save money
by reducing back-up generator sizing
requirement.

• The unit’s compact footprint requires

less floor space, leaving you with more
room for other equipment.

• Liebert NX has built in Parallel and 

Load Bus Synchronization (LBS) boards, 
no extra hardware is needed, it may be 
easily parallelized just with parallel cables.

• Liebert NX is capable of driving wide 

ranges of loads, from 0.5 lagging 
to 0.9 leading; this feature makes the
UPS able to follow the latest IT industry
trends, with more active power available
for all kind of loads.

• The Liebert NX provides the clean

est level of upstream power with

the lowest level of input current 

THDi in the industry.

The best investment you can make 
in a UPS system: Reliability, Efficiency 
and Value in a compact package.

• This ensures that clean power flows

upstream, avoiding damage to other
loads connected to the upstream 
power distribution bus.

• Liebert NX features easy and simple 

scalability and redundancy, in fact up 
to six Liebert NX modules may be 
paralleled in a redundant configuration
for added reliability and serviceability.

• The Liebert NX is compatible 

with Liebert 's unique LSB.

• Liebert NX minimizes transfers to batteries

thanks to its wide input voltage tolerance
down to 305 V.

• Temperature-compensated battery 

charging extends battery life.

• The wide input voltage window of +10 to

-20% and a frequency tolerance of 40Hz
to 70Hz provide high quality power,
even when input parameters are below
standard. This helps to minimize transfer
