Following discussions with manufacturers and end-users, EPA has revised its proposed ENERGY STAR test method for uninterruptible power supplies (UPSs), resulting in the Final Draft Test Method.

With the publication of the Final Draft Test Method, EPA hopes to begin gathering data for use in specification development. To address stakeholder concern regarding insufficient time, EPA will be splitting the dataset assembly period into two phases:
  • Phase 1: Sharing of existing test data (through January 14, 2011)
  • Phase 2: New testing according to Draft ENERGY STAR Test Method (through March 18, 2011)
