電(dian)(dian)(dian)(dian)(dian)力(li)UPS是針對(dui)中國(guo)電(dian)(dian)(dian)(dian)(dian)力(li)的(de)發展需求，專為發電(dian)(dian)(dian)(dian)(dian)廠(chang)、變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站、配電(dian)(dian)(dian)(dian)(dian)所設(she)計的(de)電(dian)(dian)(dian)(dian)(dian)源產品，具有雙變(bian)(bian)換在線式、零轉換功能。主要用于電(dian)(dian)(dian)(dian)(dian)力(li)運動、RTU、電(dian)(dian)(dian)(dian)(dian)力(li)載波、電(dian)(dian)(dian)(dian)(dian)力(li)監控(kong)等。市電(dian)(dian)(dian)(dian)(dian)正常(chang)時(shi)(shi)，單相(xiang)220V(或三相(xiang)380V)經過隔離、整流濾波后通過逆變(bian)(bian)器給負載供(gong)(gong)電(dian)(dian)(dian)(dian)(dian);若交(jiao)流電(dian)(dian)(dian)(dian)(dian)網輸入(ru)異常(chang)或斷(duan)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，則由電(dian)(dian)(dian)(dian)(dian)力(li)系統后備的(de)直(zhi)流屏經逆止(zhi)二極管逆變(bian)(bian)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，當直(zhi)流屏欠壓或斷(duan)電(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，靜態(tai)開關切換到(dao)(dao)旁路供(gong)(gong)電(dian)(dian)(dian)(dian)(dian);市電(dian)(dian)(dian)(dian)(dian)恢復正常(chang)時(shi)(shi)，自動切換到(dao)(dao)市電(dian)(dian)(dian)(dian)(dian)逆變(bian)(bian)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。若逆變(bian)(bian)器過載或故(gu)障時(shi)(shi)，轉為旁路供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，同時(shi)(shi)發出警告信(xin)號。

電力UPS主要(yao)就是給電廠(chang)內的(de)各(ge)種(zhong)比較重要(yao)的(de)負(fu)載供電,區別于普通工業UPS就是一般(ban)DC電壓(ya)是110/220VDC,同時要(yao)求隔離以及配套穩(wen)壓(ya)旁路的(de)隔離.可靠性(xing)要(yao)求高(gao)于一般(ban)UPS要(yao)求。

電力UPS與常規(gui)UPS顯著區別對比表(biao)如下：
