All are certified to meet the average current efficiency and no-load power requirements mandated by the U.S. Department of Energy (DOE) Tier VI Standards. The new series are also designed to comply with the European Union's proposed CoC Tier 2 directive, which will become law in 2018, seeking to further strengthen the efficiency requirements imposed by Tier VI and add a new energy consumption limit at 10% load.
Housed in an ultra-compact enclosure measuring just 64.6 x 36 x 22.5 mm (2.54 x 1.42 x 0.89 inches), these external AC-DC power supplies offer regulated 5 Vdc outputs, a wide universal input voltage range of 90 to 264 Vac, and no-load power consumption of less than 0.075 W. Thanks to their ultra-compact design and Class II construction, the new models are ideal for a wide range of consumer applications, including media players, e-readers, GPS devices, and other mobile devices.
The SWI3-N and SWI3-E series offer a range of standard DC output connector options, including micro USB Type-B, while the SWI3N USB and SWI3E USB series feature an integrated USB connector. Fixed-blade models for North American and Japanese applications have UL/cUL and PSE safety approvals, while European fixed-blade models carry CE and GS safety approvals. All wall-connect adapters offer overcurrent, overvoltage, and short-circuit protection and meet FCC Part 15 Class B limits for EMI/EMC.
The new SWI3 series is available immediately with prices starting at $3.90 per unit for orders of 250 units through distributors. Contact CUI for OEM pricing.
