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%.

The row-based Liebert APM is a transformer-free, on-line uninterruptible power supply (UPS) that allows quick and easy capacity increases with modular scalability--with no additional floor space required. Liebert APM operates with high efficiency--up to 94% at loads of 50-100%. The 208 Volt, three-phase Liebert APM is available in two models, expandable with modular power scalability: Liebert APM 45kVA/kW frame size is expandable from 15 to 45kVA/kW, with up to 45kVA/kW of capacity, or up to 30kVA/kW of capacity with a 15kVA/kW 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 90kVA/kW frame size is expandable from 15 to 90kVA/kW, with up to 90kVA/kW of capacity, or up to 75kVA/kW of capacity with a 15kVA/kW module for redundancy. This frame size requires the matching external battery cabinet, and is compatible with the optional Liebert APM BDC bypass distribution cabinet.

A Scalable UPS as Dynamic as Your Data Center

Prevent power interruptions and ensure the future flexibility and efficiency of your data center infrastructure, with the Liebert APM UPS. Leverage the innovative modular configuration, cost-efficient operation and flexibility to match increasing power demands all while ensuring critical reliability.

Availability and Flexibility is enhanced with standard and optional features

Obtain redundancy and scalability using innovative Liebert modular power core assemblies. Each includes distributed intelligence and scalable power in one common module.

This technology allows configuration of a completely redundant power and control system, sized to match the capacity of the protected equipment. When power requirements change, capacity is easily added – without increasing the system footprint.

The Liebert APM UPS scales from 15 to 45kW in a cabinet configuration that includes internal batteries, or from 15 to 90kW in 15kW increments in a configuration that reserves a cabinet for capacity that is paired with an external battery cabinet. This approach allows for right-sizing of the UPS, resulting in improved energy efficiency and reduced power expenditures.

Liebert APM UPS supports dynamic environments and IT growth


  • Capacity can be expanded in 15kW increments using modular power core assemblies
  • 45kW model includes internal batteries and can also obtain extended run time with external battery cabinets
  • 90kW model uses external battery cabinets only
  • Easy Installation – front service access, smaller footprint
  • 208V, 480V and 600V input configurations
  • Matching bypass and distribution cabinet – increase reliability and safety by switching the protected load to bypass power for maintenance and service
  • Top or bottom cable entry – enables installation on raised or non-raised floors

The row-based Liebert APM is ideally suited for:

  • Small to medium-size data centers
  • Server rooms
  • Production areas
  • Labs and testing facilities
  • Telecommunications
  • Process control centers
  • Edge of the network locations
