The Liebert STS2/PDU from Emerson Network Power is making it easier to protect your critical equipment by giving your single cord loads the reliability of dual cord power or by providing added redundancy to your dual cord devices. With a single, space-saving unit, the Liebert STS2/PDU static transfer switch/power distribution unit provides power distribution and automatic switching between two different AC power sources.

The Liebert STS2/PDU is available in 250A, 400A, 600A and 800A systems, in both 60Hz and 50Hz frequencies. Multiple input voltages are available. Designed for use in dual-bus power applications, this solution combines fast switching between AC power sources, power isolation, distribution, monitoring and grounding into a single package.

  • Static transfer switch with distribution
  • Provides computer-grade grounding
  • Installs and maintains easily
  • Operates energy efficiently


  • Compact single cabinet conserves valuable floorspace compared to non-packaged solutions
  • A choice of distribution options to fit site requirements
  • Easily relocated when site needs change

Higher Availability

  • Computer-grade grounding automatically establishes a single point ground to meet manufacturer and code requirements
  • Fully compatible with the non-linear loads of modern computer systems and other electronic equipment
  • Standard on-unit monitoring and optional centralized monitoring capability provide continuous system visibility

Lowest Total Cost Of Ownership

  • When applied as primary side switching, costs are lower due to requiring only one power distribution unit, a lower current due to 480V vs. 208V, and lower installation and wiring costs
  • Single cabinet design reduces installation time and cost
  • UL listed as complete system

Ideally Suited For

  • Data centers
  • Telecommunications
  • Industrial process equipment
