逐漸被開關電(dian)(dian)源(yuan)取代(dai)。電(dian)(dian)源(yuan)適(shi)配(pei)(pei)器的(de)(de)輸(shu)入是指給充(chong)電(dian)(dian)寶(bao)充(chong)電(dian)(dian)時(shi)的(de)(de)參數。如(ru)輸(shu)入為(wei)5v1a，則(ze)只能(neng)(neng)用5v的(de)(de)適(shi)配(pei)(pei)器充(chong)電(dian)(dian)，電(dian)(dian)流可以(yi)低于1a但不能(neng)(neng)超過。由于電(dian)(dian)源(yuan)適(shi)配(pei)(pei)器應(ying)用十分，所(suo)以(yi)關于電(dian)(dian)源(yuan)適(shi)配(pei)(pei)器的(de)(de)安(an)全性一直是需要(yao)(yao)考慮的(de)(de)問題。這就要(yao)(yao)求(qiu)其性能(neng)(neng)和安(an)全一定要(yao)(yao)達標，所(suo)以(yi)，電(dian)(dian)源(yuan)適(shi)配(pei)(pei)器的(de)(de)功(gong)能(neng)(neng)測試尤為(wei)重要(yao)(yao)，接(jie)下(xia)來將(jiang)從電(dian)(dian)源(yuan)適(shi)配(pei)(pei)器的(de)(de)輸(shu)入特性、輸(shu)出(chu)特性方面進(jin)行(xing)分析了解。輸(shu)出(chu)是指充(chong)電(dian)(dian)寶(bao)向(xiang)手機(ji)(ji)等設備供電(dian)(dian)的(de)(de)參數。如(ru)手機(ji)(ji)電(dian)(dian)池(chi)為(wei)5v1a，則(ze)只能(neng)(neng)用5v的(de)(de)接(jie)口充(chong)電(dian)(dian)，不能(neng)(neng)用高于1a電(dian)(dian)流的(de)(de)接(jie)口充(chong)手機(ji)(ji)。電(dian)(dian)源(yuan)的(de)(de)電(dian)(dian)磁干擾水平是較(jiao)難(nan)的(de)(de)部分，設計人員能(neng)(neng)做的(de)(de)較(jiao)多就是在(zai)設計中進(jin)行(xing)充(chong)分考慮，尤其在(zai)布局時(shi)。啟動電(dian)(dian)源(yuan)保(bao)姆

局端(duan)通訊(xun)設備(bei)還是(shi)(shi)(shi)(shi)用-48V電(dian)(dian)源(yuan)。同樣，采用負(fu)(fu)電(dian)(dian)源(yuan)系(xi)(xi)統,正極接(jie)地只是(shi)(shi)(shi)(shi)約定俗成。原來有個說法是(shi)(shi)(shi)(shi)空氣中有大量的(de)(de)負(fu)(fu)電(dian)(dian)荷，根(gen)據(ju)電(dian)(dian)化學知識，正極接(jie)地可以吸附空氣中的(de)(de)負(fu)(fu)離子，從而保護電(dian)(dian)信(xin)設備(bei)的(de)(de)外殼不被銹(xiu)蝕。其實這種說法不是(shi)(shi)(shi)(shi)很(hen)對。原電(dian)(dian)池反應和電(dian)(dian)解反應是(shi)(shi)(shi)(shi)會(hui)導致設備(bei)生(sheng)銹(xiu)，但(dan)是(shi)(shi)(shi)(shi)因為(wei)它們在(zai)設備(bei)上是(shi)(shi)(shi)(shi)以微觀形式存在(zai)的(de)(de)，幾(ji)乎沒有影響。例如非通訊(xun)系(xi)(xi)統的(de)(de)網(wang)絡都(dou)(dou)是(shi)(shi)(shi)(shi)負(fu)(fu)極接(jie)地（例如您正在(zai)使用的(de)(de)計(ji)算(suan)機），但(dan)是(shi)(shi)(shi)(shi)并(bing)沒有生(sheng)銹(xiu)。并(bing)且-48V內部都(dou)(dou)通過DC/DC隔離，DC/DC輸(shu)出的(de)(de)就是(shi)(shi)(shi)(shi)負(fu)(fu)極接(jie)地，也(ye)沒有看到(dao)單板腐蝕生(sheng)銹(xiu)。所以不論哪個極接(jie)地，都(dou)(dou)是(shi)(shi)(shi)(shi)一樣的(de)(de)。上海智能電(dian)(dian)源(yuan)充電(dian)(dian)電(dian)(dian)源(yuan)不能用粗暴的(de)(de)使用方式扔擲、敲擊移動電(dian)(dian)源(yuan)。
