Press Release Summary:

Available in SDI30-U, SDI30-UD, SDI40-U and SDI40-UD series models, Desktop Power Adapters are suitable for consumer, industrial and ITE applications. Designed in C8 or C14 inlets with 12, 15, 19 and 24 Vdc single output voltages, SDI30 and SDI40 series are housed in 111 x 52 x 32.3 mm package. Operated in 90 to 264 Vac input voltage range, units consume less than 0.075 W of no-load power and meet DoE Level VI and CoC Tier 2 standards.

Original Press Release:

30 W and 40 W Desktop Power Adapters Comply with DoE Level VI and CoC Tier 2 Standards

CUI’s Power Group today announced the addition of 30 W and 40 W desktop ac-dc power adapters to its portfolio of DoE Level VI and CoC Tier 2 compliant external power supplies. The SDI30-U, SDI30-UD, SDI40-U, and SDI40-UD series are all designed to meet the current average efficiency and no-load power requirements mandated by the US Department of Energy (DoE) under the Level VI standard. All models also meet the European Union’s (EU) proposed CoC Tier 2 directive, under review to become law in 2018, which looks to further tighten the efficiency requirements enforced by Level VI while adding a new power consumption limit at 10% load levels. Both standards 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 SDI30 and SDI40 series are available with C8 or C14 inlets and single output voltages of 12, 15, 19, and 24 Vdc. Both series are housed in a compact package measuring 4.37 x 2.05 x 1.27 in (111 x 52 x 32.3 mm) with a wide universal input voltage range of 90 to 264 Vac. The adapters carry UL/cUL, GS, PSE, and CE marks and meet the radiated and conducted emission requirements for FCC Part 15B Class B. Protections for over voltage and short circuit are also included.

Featuring no-load power consumption less than 0.075 W, these external desktop ac-dc power supplies are ideal for a variety of consumer, industrial, and ITE applications where energy consumption is a concern.

The SDI30-U, SDI30-UD, SDI40-U, and SDI40-UD series are available immediately with prices starting at $14.58 per unit at 100 pieces through distribution. Please contact CUI for OEM pricing.

Visit CUI’s booth (#311) at APEC 2017, where the company will be showcasing its Level VI and CoC Tier 2 compliant external adapters and the rest of its power portfolio ranging from 1 W to 12,000 W. APEC is the premier event for Applied Power Electronics™. The conference focuses on the practical and applied aspects of the power electronics industry, and will be held at the Tampa Convention Center in Tampa, Florida from the March 26-30, 2017.
