Achieving Maximum Protection:
Delivering Continuous Power During Virtually Any Input Condition
Every business has unique needs for their data center. If your needs focus on maximum protection in terms of availability,
look for a UPS designed to deliver the highest quality power at all times.

NXL™ UPS systems from Emerson Network Power utilize
the latest power protection technology to create a new level of
reliability and performance for data center applications.
Liebert NXL UPS systems support high power applications in
medium to large data centers that are facing growing power
demands. This Maximum Protection solution features:
Handles a stack-up of multiple adverse conditions at once
without compromising your connected IT load.
Modules with input isolation transformers maintain
on-line operation without transfer to bypass during DC
ground fault conditions. In units with input isolation
transformers (500, 625, 750 kVA), battery ground fault
isolation results in normal system operation even under battery
ground fault conditions – the system does not go to bypass.
An alarm will direct the user to take corrective action, but
operation is maintained.
Fuse-less bypass design allows fault coordination of
distribution system.
The industry leader in large UPS systems, Emerson Network
Power offers the largest and most comprehensive support
network, including applications engineering, project
manangement, a witness test facility to offer proof of
performance, and the industry’s largest global service network.
Liebert NXL UPS is the right choice for critical,
high power applications:
Listed and labeled to UL1778 fourth edition. The fourth edition is
more harmonized with internationalized standards and requires
testing for both safety and performance resulting in a more
reliable UPS
Handles a wide window of input voltage and frequency, including
power from backup generators.
Robust design allows operation at 100% load under a “stack-up”
of conditions that would require other systems to de-rate
their output or compromise system availability. Simultaneous
conditions such as clogged air filters, high ambient temperature,
high altitude, fan failure, and low or high line conditions have been
mitigated to ensure full rating at 100% operating loads.
High inverter overload rating allows the UPS to stay on inverter
delivering full regulated power, even in overload situations.
Continuous duty rated Bypass Static Switch ensures maximum
fault clearing capability in case of extreme overload or
downstream short-circuits.
