10 W Ac-Dc Power Supplies with Integrated USB Connectors

CUI announce new line of DoE Level VI and CoC Tier 2 compliant wall plug-in ac-dc power supplies featuring an integrated USB connector. The 10 W SMI10‑USB,  SWI10‑N‑USB  and SWI10‑E‑USB  are all designed to meet the stringent average efficiency and no load power requirements mandated by the US Department of Energy (DOE) in effect since February 2016. Any domestic or global manufacturer seeking to market their end product with an external adapter in the United States must meet the new Level VI standards which aim to significantly lower the amount of power consumed when the end application is not in use or is no longer connected to the system. The models also meet the European Union’s January 2018 CoC Tier 2 directive that will add additional power consumption limits at 10% load levels.

The SWI10‑N‑USB and SWI10‑E‑USB are ultra-compact, fixed blade, wall plug adapters with footprints as small as 2.03 x 1.52 x 0.93 inches (51.5 x 38.5 x 23.5 mm), making them among the industry’s smallest 10 W ac-dc power supplies to integrate a USB connector. The ac-dc adapters both feature single 5 Vdc regulated outputs with a wide universal input voltage range from 90 to 264 Vac. Both series also feature no load power consumption less than 0.075 W and provide over current, over voltage and short circuit protections.

With fixed input blades for North American and Japanese applications, the SWI10‑N‑USB offers UL/cUL and PSE safety approvals while the SWI10‑E‑USB with European fixed input blades offers CE and GS safety approvals.

Designed for global applications, the SMI10‑USB includes interchangeable ac blade options for North America, Europe, the United Kingdom, Australia and China. The 10 W multi-blade adapter also features a 5 Vdc single regulated output and a wide universal input voltage range of 90 to 264 Vac. The series meets the Level VI standard’s no load power consumption requirement of less than 0.1 W while carrying UL/cUL, CE, GS, RCM, CCC and PSE safety approvals. Protections for over voltage, over current and short circuit are also included.

All three models meet Class B limits for conducted and radiated emissions and are ideally suited for a wide range of consumer applications, including media players, e-readers, GPS and other mobile devices.

The SMI10‑USB, SWI10‑N‑USB and SWI10‑E‑USB are available immediately with prices starting at $5.90 per unit at 100 pieces through distribution.
