電源適配器又叫外(wai)置電(dian)源，是中小(xiao)(xiao)型手(shou)持式(shi)電(dian)子(zi)設備(bei)及(ji)電(dian)子(zi)電(dian)器的(de)供電(dian)系(xi)統工作電(dian)壓變換設備(bei)，多見于手(shou)機上(shang)、液晶顯(xian)示(shi)屏和筆記(ji)本(ben)等(deng)中小(xiao)(xiao)型電(dian)子(zi)設備(bei)上(shang)。下邊人們看一下電(dian)源適(shi)配器是什么主要用(yong)途(tu)。

　　1、電(dian)(dian)源適配器(qi)(qi)(Poweradapter)是中小型手持式電(dian)(dian)子設(she)備及(ji)電(dian)(dian)子電(dian)(dian)器(qi)(qi)的供電(dian)(dian)系統開關電(dian)(dian)源變(bian)換設(she)備，一般由機殼(ke)、變(bian)電(dian)(dian)器(qi)(qi)、電(dian)(dian)感(gan)器(qi)(qi)、"電(dian)(dian)容器(qi)(qi)、操(cao)縱IC、PCB板等電(dian)(dian)子器(qi)(qi)件構成.

　　2、它的原(yuan)理由溝(gou)通交(jiao)流鍵入(ru)變(bian)換為直流電輸出按(an)接口方式可分(fen)成插嵌墻和桌面型，普(pu)遍配(pei)套設施于智能(neng)安防監(jian)控攝(she)像頭(tou)，電視機頂(ding)盒(he)，無線路由,led燈條，按(an)摩(mo)器(qi)等設備中(zhong)

　　左右就是說電(dian)源(yuan)適配器的適用范圍。
