Liebert APM On-line UPS



  • High efficiency rating up to 96% in true online double conversion mode.


  • Lower mean time to repair (MMTR) with hot swappable modules.
  • Distributed intelligence : a system control in each single power module , instead of a centralized one, reduces the failure risk and increases the availability of your infrastructure .
  • High overload protection handles 110% overload for 60 minutes, 125% for 10 minutes, and 150% for 1 minute.


  • FlexPower Technology : The unit capacity is easily added, without increasing the system footprint.
  • Liebert APM, accommodates up to 5 x 30 kW power modules per rack and up to 4 UPS racks in parallel.
  • Redundant configuration allows you to substitute one module while the others are working.



  • 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

  • True on-line, double conversion technology corrects for all types of power fluctuations.
  • Provides the highest output power quality, with advanced inverter control technology.
  • Provides dual bus synchronization of two UPS units when feeding independent distribution paths.

Lowest Total Cost Of Ownership

  • Optimizes efficiency using soft-switching technology.
  • Extends battery life with temperature-compensated battery charging.
  • DSP control provides highest possible input power factor for maximum efficiency.
