Liebert NX 40-200 kVA UPS Systems  
Softscale Technology  
Liebert NX 40-200 kVA UPS systems have 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 40-200 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. 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.
Eco-Mode High Efficiency Configuration 
If selected, this operating mode switches the UPS to static 
bypass during normal operation, increasing efficiency to up to 
97% at full load. When power problems are detected the UPS 
automatically switches back to double conversion mode.
Liebert NX BDC   
The optional Liebert NX BDC provides flexibility in input and 
output voltage for a variety of applications. This cabinet is 
available in capacities to cover the Liebert NX UPS range of 
40-200kVA. The monitoring panel matches the UPS unit. Power 
and control cabling from this cabinet to the UPS is included, 
enhancing ease of installation and availability. For ease of 
installation and maintenance, the cabinet offers top or bottom 
cable entry and models are available in front and rear access, or 
front access only configurations.
