電源適配器又叫(jiao)外置電(dian)(dian)源(yuan)，是中小(xiao)(xiao)型手(shou)持式電(dian)(dian)子(zi)設備及電(dian)(dian)子(zi)電(dian)(dian)器(qi)(qi)的供電(dian)(dian)系(xi)統工作(zuo)電(dian)(dian)壓變換設備，多(duo)見于手(shou)機(ji)上、液晶顯示(shi)屏和筆記本等中小(xiao)(xiao)型電(dian)(dian)子(zi)設備上。下邊人們看一下電(dian)(dian)源(yuan)適配器(qi)(qi)是什么主要用途(tu)。

　　1、電(dian)源(yuan)適配器(qi)(qi)(Poweradapter)是中小型手持式電(dian)子(zi)設備及電(dian)子(zi)電(dian)器(qi)(qi)的供電(dian)系統開(kai)關電(dian)源(yuan)變換設備，一般由機殼、變電(dian)器(qi)(qi)、電(dian)感(gan)器(qi)(qi)、"電(dian)容器(qi)(qi)、操縱IC、PCB板等電(dian)子(zi)器(qi)(qi)件構成.

　　2、它(ta)的原理由溝(gou)通交流鍵入變換為直(zhi)流電輸出按接口方式可分成插嵌(qian)墻和桌面(mian)型，普遍(bian)配套(tao)設(she)施于智能安防監(jian)控攝(she)像頭(tou)，電視機頂盒，無線路由,led燈條，按摩器(qi)等設(she)備(bei)中(zhong)

　　左(zuo)右就(jiu)是說電源適(shi)配(pei)器的適(shi)用(yong)范圍。
