　　六級(ji)能效AC-DC電(dian)源適配器能效等(deng)級(ji)

　　能效(xiao)等級：是表示家(jia)用電器產品能效(xiao)高(gao)低(di)差別的(de)一種(zhong)分級方法，按(an)照標準相(xiang)關規定，

等級1表示(shi)產品節電(dian)已達到水平，能耗低；

等(deng)級2表示(shi)產品(pin)比較節電；

等(deng)級(ji)3表示(shi)產品能(neng)源(yuan)效率為(wei)我(wo)國市場的平均(jun)水(shui)平；

等級4表示產品(pin)能源效率低于市場平均水平；

等級5是產品市(shi)場準(zhun)入(ru)指標，低于該等級要求的(de)產品不允(yun)許生產和銷售。
