  1. EnergyEfficiencyLevelVIisComing.Areyouready? ChronologyEfficiencyStandards Intheearly1990s,itwasestimatedthatthereweremore than1 billion externalpowersupplies active inthe UnitedStates alone. The efficiencyofthesepowersupplies, mainly utilizing linear technology,couldbe as lowas 50%andstilldrawpower whentheapplicationwasturned offornoteven connected tothepowersupply (referredtoas “no‐load” condition). Experts calculatedthat withouteffortstoincrease efficienciesandreduce “no‐load” powerconsumption,externalpower supplies wouldaccount for around 30%of totalenergyconsumptioninlessthan20years.Asearly as1992,theU.S.EnvironmentalProtection Agencystarteda voluntaryprogramto promote energy efficiency andreducepollution thateventuallybecame theEnergyStar program.However,the first mandatory regulation dictatingefficiency and no‐loadpowerdrawminimumswasn’tputinplace until2004. The following sectiontracesthe pathfromthe CEC’s2004regulation uptothecurrentstandardsthatare inplace today April2009 Europe enactedErPDirective2009/125/EC(EnergyRelated Products) withscheduledstages ofimplementation for efficiency and no‐loadrequirementsequivalenttoLevel IVandLevelV standards.The scheduledefinedthattheEUwouldharmonize withLevelIVefficiencystandards by April2010andLevelVefficiencystandards by April2011.

  2. Moving Forward Inwhatwouldeffectivelybecome the “Level VI” efficiencystandard,the proposal onthetable wouldmandate no‐loadefficiencies downto0.1Wforexternalpower supplies rangingfrom1Wtoapproximately49W,boostmandatory averageefficiencyby about1%,andset standardsfor modelswithpower ratingsabove250Wforthe firsttime. The EPAestimatesthatexternalpowersupplyefficiencyregulationsimplementedoverthepastdecadehavereducedenergyconsumption by 32billionkW, saving$2.5billion annually andreducing CO2 emissions by more than24million tonsperyear. Movingbeyondthe mandatedgovernmentregulations, manyOEMsarenowstartingtodemand“greener” power suppliesasa way todifferentiate theirend products,driving efficienciescontinuallyhigherandeven pushing the implementation of controltechnologiesthatinsomecases eliminate no‐loadpowerconsumption altogether. On3February2014,theUSDepartment ofEnergy (DOE) issueda pre‐publication FederalRegister finalrule againsttheNotice of ProposedRulemaking publishedin2012.The newrule appliestoalldirectandindirectoperationexternalpowersupplies(EPS), whicharecategorisedintoeightproductclasses.It notonly increasesthe minimumenergy efficiencyrequirement ofEPSfromlevel IVtolevelVI,but alsoextendstheirscope toencompasslowervoltageAC‐orDC‐outputEPS,multiple‐voltage EPSandEPS withnameplate outputpowerexceeding250 watts.The compliancedate forthe newrequirements is10 February2016,whichistwo years afterthe rule's publicationintheFederalRegister. 4‐BJulesLane,NewBrunswick,NJ08901www.MEGAElectronics.com T732.249.2656F732.249.7442
