能源之星已經(jīng)有標(biāo)準(zhǔn)了,你到官方網(wǎng)站上查下,ERP暫時(shí)還沒(méi)有發(fā)現(xiàn)有這個(gè)標(biāo)準(zhǔn).

樓主最后是怎樣擺平客人的?說(shuō)出來(lái)給大家參考下,我們也碰到同樣的問(wèn)題了

就是這個(gè)標(biāo)準(zhǔn),樓主好人,表?yè)P(yáng)一個(gè)!!!!!!!!!!!!

在R2上並電容有些效果

問(wèn)了很多地方,目前只確認(rèn)了廣州SGS能做.

你這份是能源之星的250W以下外部電源標(biāo)準(zhǔn),樓主說(shuō)的是充電器,能源之星有專門(mén)的充電器標(biāo)準(zhǔn)

能源之星不是強(qiáng)制性的標(biāo)準(zhǔn)

美國(guó)能源部的網(wǎng)站上有,暫時(shí)沒(méi)有找到中文的,我也在搞這個(gè)標(biāo)準(zhǔn),有點(diǎn)麻煩,有消息的話通知一聲!

車載電源過(guò)ISO7637標(biāo)準(zhǔn),最難通過(guò)的是實(shí)驗(yàn)脈沖5a的要求:12V電源系統(tǒng)脈沖電壓65-87V,40-400ms,輸入阻抗0.5-4Ω;24V電源系統(tǒng)脈沖電壓為123-174V,100-350ms輸入阻抗1-8Ω.    我的車載電源已通過(guò)ISO7637標(biāo)準(zhǔn),5a脈沖電壓達(dá)174V/350ms,這么高的電壓維持時(shí)間這么長(zhǎng),如果在輸入端并聯(lián)TVS的話,5000W的TVS一擊就穿!我們?cè)谘邪l(fā)過(guò)程中也走了不少?gòu)澛?因?yàn)楫?dāng)時(shí)廣東省就沒(méi)有一家能測(cè)試ISO7637標(biāo)準(zhǔn)的實(shí)驗(yàn)室,所有樣板寄在日本做測(cè)試,花費(fèi)不少銀子.----------------------------------------------------------    2004/104/EC中規(guī)定,ESA(電子組件)的實(shí)驗(yàn)脈沖引用1.2a.2b.3a.3b.4共6個(gè)脈沖,不需做脈沖5a

能源之星2.0標(biāo)準(zhǔn)中應(yīng)該是輸出功率>75W的就要求PF>0.9,這是我從原文中摘錄的,難道我找的標(biāo)準(zhǔn)是錯(cuò)誤的?B.PowerFactorCorrectionInadditiontotheActiveModeefficiencyrequirementsfoundabove,allqualifyingpowersupplieswithanameplateoutputpower(Pno)ofgreaterthanorequalto75wattsmusthaveatruepowerfactorof0.9orgreaterwhenmeasuredat100%ofratedoutput.Note:Inrecentyears,therehasbeenincreasedinterestfromtheinternationalefficiencycommunityindecreasingtheeffectthathighwattageproductshaveonpowerquality.Tothisend,EPAhasincludedpowerfactorrequirementsforhighpowerdevices.PowerfactorcorrectionhelpstocutI-squaredRlossesinbuildingdistributionwiringsignificantly,yieldingincreasedsavingsinlargebuildings.Forthepurposeofthisspecification,allEPSswithapoweroutputofatleast75wattswillberequiredtohaveapowerfactorofatleast0.9at100%ofratedload.This75-wattcutoffcoincideswiththeEuropeanregulationEN61000-3-2,whichwentintoeffectin2001andrequireslimitedtotalharmonicdistortionforappliancesabove75wattsinputpower.Apowerfactorofatleast0.9at100%ofratedloadisconsistentwiththeinternalpowersupplyrequirementintheVersion4.0ENERGYSTARComputerspecification.Attheselevels,approximately90%ofcurrentENERGYSTARqualifiedpowersuppliescanmeetthisrequirement.
