CUI’s 3 W wall plug adapters are the latest additions to their portfolio of DoE Level VI and CoC Tier 2 compliant external power supplies. The SWI3-N and SWI3-N-USB series, available with North American input blades, and the SWI3-E and SWI3-E-USB series, featuring European input blades, are all certified to meet the current average efficiency and no-load power requirements enforced by the US Department of Energy’s (DoE) Level VI standards. The new series are also designed to meet the European Union’s proposed CoC Tier 2 directive, under review to become law, which looks to further tighten the efficiency requirements enforced by Level VI while adding a new power consumption limit at 10% load levels.
