CUI Inc.’s line of ultra-compact 5 W wall plug adapters are designed to meet the stringent average efficiency and no-load power requirements mandated by the US Department of Energy (DoE) Level VI Standards and the European Union’s proposed CoC Tier 2 directive. These required and proposed laws have implications for any OEM that designs products with an external AC-DC power supply for the US and European markets.

With a footprint as small as 2.56 in. x 1.42 in. x 0.89 in. (64.92 mm x 36 mm x 22.5 mm), these adapters are among the industry’s smallest AC-DC power supplies to integrate a USB connector. The ultra-compact design makes it ideally suited for a wide range of consumer applications, including media players, e-readers, GPS, and other mobile devices.

Designed with input blades for North American and Japanese applications, the SWI5-5-N-I38 offers 60950-1 UL/cUL and PSE safety approvals while the SWI5-5-E-I38 with European input blades offers GS safety approvals. All models meet Class B limits for conducted and radiated emissions.
