什么是電源適配器?使用(yong)電(dian)源適(shi)配器相對有哪(na)些作(zuo)用(yong)呢?在什么情況下用(yong)外置(zhi)的電(dian)源適(shi)配器比較好呢?下面小編(bian)就這些問題做簡單介紹。

　　什么是電源適配器?定義?

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi)是(shi)小(xiao)型(xing)便攜式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設(she)備及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)變(bian)換設(she)備，一(yi)(yi)般由(you)外殼、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)變(bian)壓器(qi)(qi)(qi)(qi)(qi)和(he)整(zheng)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路組(zu)成，按其輸入類型(xing)可分為交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi)和(he)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi);按連接方式(shi)(shi)可分為插(cha)墻式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi)和(he)桌面(mian)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi)。廣(guang)泛配(pei)(pei)套于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)子(zi)母機、游(you)戲(xi)機、語言復讀機、隨身(shen)聽、筆記本計算機、蜂窩(wo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)話(hua)等設(she)備中。在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi)上(shang)都有一(yi)(yi)個銘牌，上(shang)面(mian)標示(shi)著功率，輸入輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)量等指標，特(te)別(bie)要注意(yi)輸入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)(de)范圍，這(zhe)就是(shi)所(suo)謂(wei)的(de)(de)(de)“旅(lv)行(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)(qi)(qi)”，如果到(dao)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓只(zhi)有100V的(de)(de)(de)國家時，這(zhe)個特(te)性就很有用了，有些水貨筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦是(shi)只(zhi)在原產地銷售的(de)(de)(de)，沒有這(zhe)種設(she)計，甚至(zhi)只(zhi)有100V的(de)(de)(de)單一(yi)(yi)輸入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，在我國的(de)(de)(de)220V市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓下插(cha)上(shang)就會燒毀。

　　電(dian)(dian)源(yuan)適(shi)配(pei)器的(de)(de)作(zuo)用就(jiu)是提(ti)供(gong)設備正常(chang)工(gong)作(zuo)所需要的(de)(de)能量。就(jiu)是給設備供(gong)電(dian)(dian)。有(you)的(de)(de)外置(zhi)有(you)的(de)(de)內置(zhi)，與設備的(de)(de)應(ying)用和(he)設計者(zhe)有(you)關(guan)。 因為電(dian)(dian)源(yuan)適(shi)配(pei)器上有(you)相(xiang)應(ying)的(de)(de)過溫(wen)保(bao)護功(gong)能，因此使(shi)(shi)用電(dian)(dian)源(yuan)適(shi)配(pei)器可(ke)以(yi)(yi)保(bao)護設備不受高溫(wen)的(de)(de)損(sun)(sun)害，穩定可(ke)靠的(de)(de)工(gong)作(zuo)，同時具有(you)過流、過壓、過載保(bao)護功(gong)能，使(shi)(shi)設備不會因為電(dian)(dian)流、電(dian)(dian)壓等的(de)(de)波動而(er)損(sun)(sun)壞。外置(zhi)的(de)(de)電(dian)(dian)源(yuan)適(shi)配(pei)器使(shi)(shi)用比(bi)較靈活(huo)，只要可(ke)以(yi)(yi)符合設備要求的(de)(de)參數，就(jiu)可(ke)以(yi)(yi)使(shi)(shi)用同一個適(shi)配(pei)器。不過為保(bao)證設備的(de)(de)正常(chang)運行，選擇時一定要選擇正規廠家生產的(de)(de)電(dian)(dian)源(yuan)適(shi)配(pei)器。
