A Scalable Power Solution for Dynamic Demands

Provide mission-critical availability while reducing costs and maintaining flexibility for the future with the Liebert APS UPS, a scalable, modular power solution for 5 to 20kVA applications.


With the Liebert APS UPS, you can maintain flexibility for the future and ensure the availability of your critical systems– all while obtaining energy efficiency.

  • Industry-leading efficiency:
    • 91.5-92% efficiency: 200-240V in/out transformer-free models.
    • 90-91% efficiency: 200/100-240/120V in/out transformer-free models.
    • 88.5-89.9% efficiency: transformer-based models.
  • Modular batteries, controls and power components to help reduce maintenance costs with user replacement.
  • Scalability that allows you to cost-effectively add power capacity or battery modules as needed.
  • Module-level redundancy eliminates the expense of purchasing and planning for additional cabinets.
  • Reduced installation time and cost because units are shipped pre-configured and factory tested.
  • Integrated into one system: power modules, batteries, maintenance bypass, and distribution in a single, small-footprint cabinet.
  • Integral battery monitoring with temperature compensated charging to prolong battery life and help reduce replacement costs.
  • Two year hassle-free factory warranty program for repair or replacement.


Reliability and ServiceabilityReliability and Serviceability

Your business depends on the data center and the IT network to run. With the Liebert APS UPS solution, you get peace of mind that your critical IT functions – and your business – will be available and running as expected through power disruptions, fluctuations and outages.

  • Internal redundancy capability (N+2/20kVA) enhances reliability and provides multiple layers of protection.
  • No single point of failure - Full redundant design allows the critical load to run on conditioned power if there is a failure of any component.
  • Configurable design provides your desired level of capacity and redundancy.
  • Fault-tolerant design, enables the power, battery and control modules to take themselves offline if there is a problem, without sacrificing overall system integrity.
  • Superior overload capabilities, able to provide conditioned power to temporary overloads without transfers to/from bypass power.
  • Internal wrap-around maintenance bypass and Frame-level bypass with independent controls in separate assembly provide higher reliability and availability

Low TCO for Today, Flexibility for the Future


The Liebert APS UPS helps you enhance flexibility to stay ready for what’s next:

  • Capacity on demand with FlexPower core modules delivers capacity changes in 5 kVA/4.5 kW increments - without powering down.
  • More real kW - 0.9 power factor provides more real power to support the I.T. load than many other solutions in this size range.
  • Isolated and non-isolated models to provide the protection and efficiency you need.
  • Trellis platform connectivity, so the Liebert APS can easily be integrated with this robust, real-time data center optimization solution.
  • Communications card option to fit your needs, allow integration with a variety of infrastructure management solutions.
      • Communications and Environmental MonitoringIS-UNITY-DP provides LIFE Services, Web Interface, SNMP, Modbus IP / RTU, BACNet IP / MSTP, & Envrionmental Sensor support. (temperature, humidity, contact closure, leak detection and more).
      • IS-485EXI provides communication with Liebert SiteScan
      • IS-RELAY provides 5 contact closures
      • IS-MULTIPORT provides interface from Trellis Power Insight shutdown software to up to 4 computers
  • Optional matching external battery cabinets.
  • Installation Flexibility – use on raised floors, non-raised or in rack.
  • Large input voltage window, which minimizes transfer to battery and increases battery life; low line transfer can range down to 110v.
  • Integrated distribution PODs create the right distribution options to meet application requirements.
