Liebert NX UPS with SoftScale
™
(40-120 kVA)
The ne
w Liebert NX UPS with SoftScale™ technology combines the industry’s
most flexible approach to scalability with an efficiency rating of up to 97%.
It is designed for small and medium size data centers that are facing
un
predictable changes in their IT systems.
The Liebert NX with SoftScale™ can be sized to current requirements and
then be easily scaled up in 20kVA increments. When an upgrade is
purchased an Emerson Customer Engineer will visit the site and install a
software key to complete the capacity upgrade. Modules can adapt from 40
kVA to 60 kVA to 80 kVA or from 80 kVA to 100 kVA to 120 kVA. In addition,
modules with identical or different ratings can work in parallel to handle
higher capacities.
These Liebert NX modules can be positioned in a row of racks alongside the
IT equipment it protects to optimize space utilization.

Lowest Total Cost Of Ownership:
n
Soft-switching technology optimizes
operation with the same high efficiency
at 40% utilization as at 100% utilization.
n
Adaptive input voltage window results
in fewer hits on the battery.
n
The unit’s compact footprint requires
less floor space, leaving you with more
room for other equipment.
