The US Department of Energy’s revision to its EISA 2007 external power supply (EPS) efficiency standard, which came into effect this year, increased the minimum efficiency requirements as well as expanding the range of products applicable under the new standard.

In Europe, the EU’s proposed CoC Tier 2 directive, which is even more stringent, looks set to become mandatory Ecodesign rules in January 2018.

Tom Busher, vice-president of I P & E at Digi-Key, writes:

“CUI has taken a leadership role in addressing the increasing concerns for no-load and active mode power consumption of external adapters. We have worked closely with them to develop a variety of efficiency standard resources that will help keep customers informed, in addition to getting compliant products to market faster.”

CoC Tier 2 and DoE Level VI resources available on the Digi-Key website include a Product Training Module (PTM)
