電源適配器又叫外置電源(yuan)，是(shi)中(zhong)(zhong)小(xiao)型(xing)手持式(shi)電子設備(bei)及電子電器的供電系統工作電壓(ya)變(bian)換(huan)設備(bei)，多見于手機(ji)上(shang)(shang)、液(ye)晶顯(xian)示屏和筆記(ji)本等中(zhong)(zhong)小(xiao)型(xing)電子設備(bei)上(shang)(shang)。下(xia)邊(bian)人們(men)看一下(xia)電源(yuan)適配器是(shi)什么主要用途。

　　1、電(dian)(dian)源適配器(qi)(Poweradapter)是(shi)中小(xiao)型(xing)手持式(shi)電(dian)(dian)子(zi)設備(bei)(bei)及電(dian)(dian)子(zi)電(dian)(dian)器(qi)的供電(dian)(dian)系(xi)統開(kai)關(guan)電(dian)(dian)源變換設備(bei)(bei)，一般由機殼(ke)、變電(dian)(dian)器(qi)、電(dian)(dian)感器(qi)、"電(dian)(dian)容器(qi)、操縱IC、PCB板等電(dian)(dian)子(zi)器(qi)件構成.

　　2、它的原(yuan)理由溝通(tong)交(jiao)流(liu)(liu)鍵入變換為直流(liu)(liu)電(dian)輸出按接口方(fang)式可分成(cheng)插(cha)嵌(qian)墻和桌(zhuo)面型，普遍配套設(she)施于智能安防監控攝(she)像頭，電(dian)視機頂(ding)盒(he)，無線路由,led燈條，按摩(mo)器等設(she)備中(zhong)

　　左右就(jiu)是(shi)說(shuo)電(dian)源適配器的(de)適用(yong)范圍。
