This product is discontinued.

The row-based Liebert APM is a transformerless, on-line UPS that allows quick and easy capacity increases with modular power scalability – no additional floor space required. The UPS operates with high efficiency – up to 94% at loads of 50-100%.


  • Operates with high efficiency rating - up to 94%
  • Scalable UPS protection for growing data centers
  • Capacity expansion in 15kVA/kW increments using modular power assemblies
  • Modular power offers capacity growth without increasing footprint
  • Fits row-based applications
  • Large and user-friendly LCD display with operating information in twelve languages.
  • LIFE Services for remote monitoring and proactive services delivery
  • ENERGY STAR qualified


  • Internal bypass allows modular power assemblies to be added or replaced without powering down the connected equipment.
  • Conveniently positioned, easy-to-reach lug holes simplify unit wiring and installation.Higher Availability
  • True on-line, double conversion technology corrects for all types of power fluctuations.
  • Redundancy features minimize single points of failure.
  • Enterprise-quality batteries in an external battery cabinet provides backup time for 90kVA/kW unit, and additional runtime for 45kVA/kW unit.
  • Optional bypass distribution cabinet (BDC) provides wraparound maintenance bypass, so the attached load can keep running during UPS service.Lowest Total Cost Of Ownership
  • Buy only what you need for present usage, with the flexibility to add capacity as demand increases.
  • High operating efficiency (up to 94%), with a virtually flat efficiency curve from 50-100% load; efficiency is not load-dependent, which translates into significant energy cost savings.
  • Fewer batteries mean less maintenance and higher reliability.
  • Operates with unity power factor, where kW = kVA, providing more real power capacity without power losses.
