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.

Eco-Mode High Efficiency Configuration

To save energy, this operating mode switches the UPS to static bypass during normal operation. When power problems are detected the UPS automatically switches back to double conversion mode.

Liebert NX Maintenance Bypass And

Distribution Cabinet

The optional Liebert NX Maintenance Bypass and Distribution Cabinet 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 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 requires only front and back.
