Level VI-Compliant Ac-Dc Power Supplies

CUI Inc. announced a family of Level VI compliant external ac-dc power supplies ranging from 5 W to 36 W that feature interchangeable ac input blades. Designed for global use, the wall plug-in SMI5-USB, SMI6, SMI18, SMI24 and SMI36 include ac blade options for North America, Europe, the United Kingdom, Australia and China. The series are all designed to meet the stringent 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. Any domestic or global manufacturer seeking to market their end product with an external adapter in the United States must meet these new performance standards mandated by the US Department of Energy (DOE) by Feb. 10, 2016.

The 5 W, 6 W, 18 W, 24 W and 36 W multi-blade adapters feature a wide universal input voltage range of 90~264 Vac and are available in single output voltages from 5~48 Vdc depending on the series. All models meet the Level VI standard's no load power consumption requirement of < 0.1 W. Protections for over voltage, over current and short circuit are also included and vary by series.

The SMI5-USB comes with an integrated USB connector and offers UL/cUL, GS and RCM safety approvals, while the SMI6 series also includes CCC and PSE safety approvals. The SMI18 and SMI24 series both offer UL/cUL, GS and PSE safety approvals, while the SMI36 series also holds the CCC safety approval. All models meet FCC Part 15 Class B standards for EMI/EMC and bear the CE mark.

The new SMI5-USB, SMI6, SMI18, SMI24 and SMI36 series are available immediately through distribution with prices starting at $7.93 per unit at 100 pieces. Please contact CUI for OEM pricing.
