Energy Conservation Program: Test Procedure for External Power Supplies

The U.S. Department of Energy ("DOE") is proposing to revise its test procedure for external power supplies ("EPS" or "EPSs"). DOE is proposing to add a definition for "commercial and industrial power supply" in its regulations to differentiate between EPSs and other non-consumer power supplies that are not subject to the test procedure. DOE also proposes to add a definition to address an adaptive EPS that conforms to the Universal Serial Bus Power Delivery ("USB-PD EPS") specifications and revise its procedure to address their testing in a manner more representative of their actual use. Further, the proposed revisions would provide more specific instructions for testing single-voltage EPSs that have multiple output busses. Lastly, DOE proposes to reorganize the test procedure to centralize definitions, consolidate generally applicable requirements, and better delineate requirements for single-voltage, multiple-voltage, and adaptive EPSs. DOE is seeking comment from interested parties on the proposal.
