適應(yīng)外部電源供應(yīng)到新的水平VI規(guī)格

　　符合能源之星標(biāo)準(zhǔn)一樣，由美國環(huán)境保護(hù)署（EPA）的產(chǎn)生和能源部（DOE），外部電源（EPS）或適配器制造商繼續(xù)改善待機(jī)或空載功耗，其開關(guān)電源（SMPS）整體轉(zhuǎn)換效率超過二十年。現(xiàn)在，新標(biāo)準(zhǔn)有望進(jìn)一步提高對(duì)新一代外部電源的酒吧。美國能源部已經(jīng)建立了新的水平VI規(guī)范，預(yù)計(jì)將于二月在美國生效。

　　在這個(gè)日期之后，原始設(shè)備制造商必須確保外部電源適配器伴隨他們的產(chǎn)品在美國銷售必須符合新的水平VI法規(guī)。國際效率標(biāo)記協(xié)議要求符合標(biāo)準(zhǔn)的EPS供應(yīng)二月后必須在其產(chǎn)品標(biāo)簽上顯示VI級(jí)標(biāo)記。

　　Currently， however， the U.S. and Canada require external-power adapters to meet Level IV requirements while the European Union （EU） demands such units to carry Level V markings. But experts believe that the EU and Canada will quickly follow the U.S. lead， requiring OEMs to ensure that all external power supplies are compliant with Level VI regulations.

　　The new standard is designed to conserve power primarily in consumer and industrial products， while medical power supplies are exempt from the new DoE regulations. According to power supply manufacturer CUI， any products approved by the U.S. Food and Drug Administration are not part of this new regulation. CUI in fact， is one of the few suppliers that is already offering Level VI-compliant EPSs.
