The row-based Liebert APM is a transformer-free, on-line uninterruptible power supply (UPS) that allows quick and easy capacity increases with FlexPower™ hardware assemblies--with no additional floorspace required. Liebert APM operates with the industry's highest data center power efficiency--up to 94% at loads of 50-100%.

The 208 Volt, three-phase Liebert APM is available in two models, expandable with FlexPower hardware assemblies:

  • Liebert APM 45kW frame size is expandable from 15 to 45kW, with up to 45kW of capacity, or up to 30kW of capacity with a 15kW module for redundancy. This frame size includes internal batteries, and is compatible with the matching external battery cabinet and the optional Liebert APM bypass distribution cabinet (BDC).
  • Liebert APM 90kW frame size is expandable from 15 to 90kW, with up to 90kW of capacity, or up to 75kW of capacity with a 15kW module for redundancy. This frame size requires the matching external battery cabinet, and is compatible with the optional Liebert APM BDC bypass distribution cabinet.
  • Scalable UPS protection for growing data centers
  • FlexPower assemblies offer capacity growth without increasing footprint
  • Operates with the industry's highest efficiency rating - up to 94%
  • Fits row-based applications
Features

Flexibility

  • Capacity expansion in 15kW increments using FlexPower assemblies.
  • Internal bypass allows FlexPower assemblies to be added or replaced without powering down the connected equipment.
  • Offers a large and user-friendly LCD display with operating information in twelve languages.
  • 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 90kW unit, and additional runtime for 45kW 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.
  • Industry’s highest reported efficiency rating (up to 94%), with a virtually flat efficiency curve from 50-100% load; efficiency is not load-dependent –translates into significant energy cost savings.
  • Fewer batteries mean less maintenance and higher reliability.
  • Operates with unity power factor — kW = kVA, providing more real power capacity without power losses.

Ideally Suited For

  • Small to mid-size data centers
  • Server rooms
  • Production
  • Labs and testing facilities
  • Telecommunications
  • Process control centers
