Is Your Power Supply Level VI Compliant?

On February 10, 2014, the U.S. Department of Energy (DOE) published a revision to its EISA 2007 external power supply (EPS) efficiency standard increasing the minimum efficiency requirements as well as expanding the range of products applicable under the new standard. Set to go into effect February 10, 2016, this law will have implications for any OEM that designs products with an external ac-dc power supply for the US market. To keep you one step ahead, CUI is developing a robust portfolio of Level VI compliant external ac-dc adapters utilizing the latest in green power technology.
