DOE announced new efficiency standards for external power supplies

“The efficiency standards established will update 2007 standards for Class A external power supplies to make these components up to 33 percent more efficient. The final rule also establishes efficiency standards for non-Class A external power supplies, which go beyond Class A components to convert to multiple voltages at the same time, output more than 250 watts or provide power to a motor-operated product.”

DOE Building Technologies Office website provides information regarding Direct Operation EPS Standards and Class A EPS Efficiency Standards as well est procedures, waiver, exception and exemption information, statutory authority and historical information.
