Liebert NX 40-120 kVA UPS Systems
Softscale Technology
Liebert NX 40-120 kVA UPS systems are available with Liebert
Softscale technology that provides flexibility to increase UPS capacity
by 20 or 40kVA without changes in your infrastructure. Allows
paralleling of unlike-sized models for capacity or redundancy.
Designed for optimized performance with the same high efficiency at
40% utilization as at 100% utilization.
Paralleling Capabilities
Liebert NX 40-120 kVA systems allow you to parallel UPS modules for
capacity and redundancy, eliminating the batteries as a single point
of failure because each UPS has its own isolated battery. Liebert NX
also features integrated dual bus synchronization as a standard
feature on models with Softscale technology. This provides the
capability to synchronize the outputs of two independent UPS
modules when they are configured as a redundant system feeding
independent distribution paths.

converts the UPS system’s 480VAC output to 208/120VAC. This
cabinet is available in capacities of 75kW and 125kW covering the
Liebert NX UPS range of 40-120kVA. The front and back door panels
and the on-unit monitor panel are matched to the UPS unit. Power
an

enhancing ease of installation and availability. For ease of installation
an
d maintenance, the cabinet offers top or bottom cable entry and
requires only front and back.
