電源適配器又叫外置電(dian)(dian)(dian)源(yuan)(yuan)，是中小型(xing)手(shou)持式電(dian)(dian)(dian)子設備(bei)及電(dian)(dian)(dian)子電(dian)(dian)(dian)器(qi)的(de)供電(dian)(dian)(dian)系統工(gong)作電(dian)(dian)(dian)壓變(bian)換設備(bei)，多見于手(shou)機上、液晶顯示屏和筆記(ji)本等中小型(xing)電(dian)(dian)(dian)子設備(bei)上。下邊人們(men)看一下電(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)是什么(me)主(zhu)要(yao)用途(tu)。

　　1、電(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)(qi)(qi)(Poweradapter)是中(zhong)小型手持式(shi)電(dian)(dian)子設備及電(dian)(dian)子電(dian)(dian)器(qi)(qi)(qi)的(de)供(gong)電(dian)(dian)系統開關電(dian)(dian)源(yuan)(yuan)變換設備，一(yi)般由機殼、變電(dian)(dian)器(qi)(qi)(qi)、電(dian)(dian)感器(qi)(qi)(qi)、"電(dian)(dian)容器(qi)(qi)(qi)、操(cao)縱IC、PCB板等電(dian)(dian)子器(qi)(qi)(qi)件構成.

　　2、它(ta)的原理由溝通交流鍵(jian)入變換為直流電輸出(chu)按接口(kou)方式(shi)可分成插(cha)嵌墻和桌面型，普遍配套設施于(yu)智能(neng)安防(fang)監(jian)控攝像頭，電視機頂盒(he)，無(wu)線路由,led燈(deng)條，按摩器等設備中

　　左右就是說(shuo)電源適(shi)配器的適(shi)用范圍(wei)。
