The US Department of Energy (DOE) announced earlier this year that it was revising its external power supply efficiency requirements. This latest revision to the 2007 Energy Independence and Security Act (EISA) has been broadened to include power supplies over 250W, multiple output voltage devices and LED drivers.
From February 2016, all external power supplies sold into the US market will have to conform to the revised DOE standards of improved energy efficiency and lower standby losses. Compliant power supplies must be marked up with the Roman Numeral VI.
As usual, there are exceptions to these requirements; the main one being power supplies for medical equipment. Other exceptions include power supplies for lifesaving and safety equipment and certain low powered devices for recharging batteries that primarily drive a motor (such as e-bikes or power tools).
Friwo, represented by Haredata Electronics in the UK, will be launching their brand new range of DOE compliant power supplies at Electronica 2014, November 11-14th, in Munich. If you can’t make it to Germany, then Haredata Electronics will be launching the new product ranges in the UK shortly afterwards.
