CUI’s External Ac-Dc Power Supplies Now Meet EU’s CoC Tier 2 Efficiency Standards

CUI today announced that the majority of its line of external ac-dc power supplies now meet the European Union’s (EU) Code of Conduct (CoC) Tier 1 and CoC Tier 2 efficiency standards.

The European Union’s CoC Tier 1 effectively harmonizes the EU with US DoE Level VI and became effective as a voluntary requirement from January 2014, two years ahead of Level VI. Its adoption as an EU Ecodesign rule is currently under review to become law with an implementation date of January 2017. The more stringent CoC Tier 2 requirement became effective on a voluntary basis from January 2016 and is similarly under review to become law as an Ecodesign rule from January 2018.

The key difference between the CoC requirements and Level VI is the new 10% load measure, which imposes efficiency requirements under a low-load condition where historically most types of power supplies have been notoriously inefficient. While CoC Tier 1 includes the new 10% load measure, its no-load and active mode limits are less stringent than DoE Level VI. CoC Tier 2 further tightens the no-load and active mode power consumption limits for key classes of power adapters enacted by Level VI and covers both standard voltage and low voltage adapters.

“This announcement is a part of CUI’s ongoing effort to stay ahead of the rapidly evolving global efficiency regulations,” stated Kraig Kawada, VP of Product Management at CUI. “Though the EU’s CoC standards are still voluntary, we want to make sure our customers’ designs are properly future-proofed in the event that these tighter efficiency rules become law.”

All of CUI’s DoE Level VI and EU CoC Tier 2-compliant models are currently available through distribution. Please contact CUI for OEM pricing.

Visit CUI’s booth (Power Hall A2, Booth 613) at electronica 2016 where the company will be showcasing their Level VI and CoC Tier 2 compliant external adapters and the rest of their power portfolio ranging from 1 W to 12,000 W. electronica is the world’s leading trade fair for electronic components, systems and applications, and will be held at the Messe München in Munich, Germany from November 8-11, 2016.
