CUI Inc.- Wall Plug AC/DC Power Supplies Comply with New Tighter Efficiency Regulations


CUI Inc has announced a new line of wall plug AC/DC power supplies for the US, Japanese and European markets.

The SWI6, SWI12, SWI18 and SWI24, which have either North American or European input blades, meet the stringent average efficiency and no-load power requirements mandated by the US Department of Energy in its new Level VI standard. The aim of this standard is to markedly lower the amount of power consumed when the end application is not in use or is no longer connected to the system. Any manufacturer seeking to market an end product with an external adapter in the US must comply with these new provisions by February 10, 2016.

The 6W, 12W, 18W and 24W SWI wall plug adapters all feature a wide universal input voltage range of 90-264V AC and are available in single output voltages of 5V, 5.9V, 9V, 12V, 15V or 24V. All models meet the Level VI standard’s no-load power-consumption requirement of <0.1W.

Models with input blades for North American and Japanese applications offer UL/cUL and PSE safety approvals, while models with European input blades come with the CE mark. All models also satisfy the requirements of the FCC Part 15 Class B standard for EMI/EMC.
