Liebert Npower On-Line (30-130kVA)

Liebert Npower uninterruptible power supply (UPS) system features one of the industry’s smallest footprints in a full-featured, high power UPS system. All-digital controls allow for ultra-fast adjustments to changing data center power loads. Liebert Npower is rugged enough to handle load branch faults, input faults, 100% step loads, PDU startup inrush and motor-load startup. Liebert Npower is available in seven models ranging from 30kVA to 130kVA; 208, 220, 240, 480 or 600VAC; 60Hz. Multiple configuration options are available, including single module, 1+1 redundant for single bus systems, and single and dual input.


  • Excellent efficiency powering non-linear and partial loads.
  • All-digital controls feature a unique, patent-pending technology that allows it to make ultra-fast adjustments to changing loads.
  • Installation flexibility thanks to small footprint.

Higher Availability

  • Proven double-conversion technology protects against the widest range of input and output power disturbance.
  • Exceptional overload capability due to combination of rugged inverter and continuous-rated static switch.
  • Dual-Bus configuration allows concurrent maintenance, resulting in virtually 100% availability of conditioned power.
  • Liebert three-phase UPS products have field-proven critical bus MTBF in excess of one million hours.

Lowest Total Cost Of Ownership

  • Excellent operating efficiency — typically between 92% and 93.5% — while powering high-crest-factor loads between 50% and 100% of rated capacity.
