Energy Conservation Program: Test Procedure for Uninterruptible Power Supplies

The U.S. Department of Energy ("DOE") is amending the test procedure for uninterruptable power supplies ("UPSs") to incorporate by reference relevant portions of the latest version of the industry testing standard, harmonize the current DOE definitions for UPS, total harmonic distortion, and certain types of UPSs with the definitions in the latest version of the industry standard, and add a no-load testing condition, as an optional test.

The effective date of this rule is 3 July 2024. The amendments will be mandatory for product testing starting 16 October 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register on 3 July 2024.
