Energy Conservation Program: Test Procedures for External Power Supplies

The U.S. Department of Energy is proposing to revise its test procedure for external power supplies. These proposed revisions, if adopted, would harmonize the instrumentation resolution and uncertainty requirements with the second edition of the International Electrotechnical Commission (IEC) 62301 standard when measuring standby power along with other international standards programs. The proposal would also clarify certain testing set-up requirements. Finally, DOE is proposing an optional test to measure the active-mode efficiency at a 10% loading condition and an optional recording of power factor at this loading condition and each of the other required loading conditions.
