Efficiency Standards for External Power Supplies
More InfoLess Info
The global regulatory environment surrounding the legislation of external power supply efficiency and no-load power draw has rapidly evolved over the past decade since the CEC implemented the first mandatory standard in 2004. Mandating higher average efficiencies in external power supplies has undoubtedly had a real impact on global power consumption. However, with the benefit of a reduced draw on the power grid come challenges and uncertainties for the electronics industry as it tries to keep up with this dynamic regulatory environment. The goal of this paper is to provide an up to date summary of the most current regulations worldwide.
