Liebert NX

Liebert NX 40 – 200kVA

Liebert NX uninterruptible power supply (UPS) with Softscale technology is a true on-line, double conversion, three-phase UPS system that provides a scalable solution to optimize data center power design. Uninterruptible power can grow from 40 to 60 to 80kVA, from 80 to 100 to 120kVA, and from 160 to 200kVA.

Product Description

The 480-volt, three-phase Liebert NX is available in both scalable and standard models:

  • Liebert NX with Softscale™ technology is a full-featured UPS available in scalable models: 40 to 60 to 80kVA, and 80 to 100 to 120kVA, and 160 to 200kVA. Up to three unlike or like capacities may be paralleled for capacity; up to four unlike or like capacities may be paralleled for redundancy.
  • Liebert NX fixed capacity models are available in 40, 60, 80, 100 and 120, 160 and 200 kVA.


  • Scalable UPS protection for growing data centers
  • Offers models with capacity growth without increasing footprint
  • Allows parallel configurations for capacity or redundancy
  • Operates with up to 97% energy efficiency



  • Provides an economical path for growth, with Softscale technology.
  • Allows paralleling of unlike capacities for capacity or redundancy.
  • Offers a large and user-friendly LCD display with operating information in twelve languages.
  • Includes a built-in automatic bypass to transfer the load in case of fault.

Higher Availability
