February 19, 2014 - A few days ago, the U.S. Department of Energy (DOE) published a revision to its EISA 2007 external power supply (EPS) efficiency standard. The new standard:
- Tightens the current EISA2007 active-mode and no-load efficiency requirements
- Expands the range of products to include multiple-voltage EPSs
- Raises the EPS output power level to > 250 watts
Compliance to the new levels becomes mandatory on February 16, 2016. The requirements are shown in Table 1 and 2 below.
