POE (Power Over Ethernet)指的是在現(xiàn)有的以太網(wǎng)Cat.5布線基礎(chǔ)架構(gòu)不作任何改動(dòng)的情況下,在為一些基于IP的終端(如IP電話機(jī)、無線局域網(wǎng)接入點(diǎn)AP、網(wǎng)絡(luò)攝像機(jī)等)傳輸數(shù)據(jù)信號(hào)的同時(shí),還能為此類設(shè)備提供直流供電的技術(shù)。 POE也被稱為基于局域網(wǎng)的供電系統(tǒng)(POL, Power over LAN )或有源以太網(wǎng)( Active Ethernet),有時(shí)也被簡(jiǎn)稱為以太網(wǎng)供電,這是利用現(xiàn)存標(biāo)準(zhǔn)以太網(wǎng)傳輸電纜的同時(shí)傳送數(shù)據(jù)和電功率的標(biāo)準(zhǔn)規(guī)范,并保持了與現(xiàn)存以太網(wǎng)系統(tǒng)和用戶的兼容性。
標(biāo)準(zhǔn)POE電源的相當(dāng)于智能的,在供電前會(huì)自動(dòng)檢測(cè)受電設(shè)備支持PoE供電的才會(huì)供電,否則沒反應(yīng),選擇標(biāo)準(zhǔn)的PoE供電模塊就可。
我司POE電源特點(diǎn):
1.電源具有輸入過欠壓、輸出過壓、每路輸出過流短路保護(hù)等功能
2.帶有電源指示燈,方便了解工作狀態(tài)
3.外觀小巧精致,插墻式設(shè)計(jì),也有桌面型設(shè)計(jì)
