style="text-indent:25px">5G未來已來，通信電源時至勢成。通信電源在5G時代受益的程度和持續(xù)時間遠(yuǎn)高于4G時代,主要的驅(qū)動力來自于基站和數(shù)據(jù)中心。基站設(shè)備大功耗驅(qū)動通信電源需求.5G時代，基站設(shè)備（AAU 和BBU）功率大幅提升,是通信電源需求大爆發(fā)的主要驅(qū)動力之一。AAU方面，為彌補工作頻段上升導(dǎo)致的基站覆蓋性能下降，同時為配合大規(guī)模陣列天線Massive MIMO 技術(shù)的應(yīng)用，5G 基站單扇區(qū)AAU的機頂輸出功率有望從4G的40-80w增加至200W甚至更高。而BBU方面，基帶處理能力大幅提升，電源功率的要求也將大幅提升。AAU 和BBU 的功率需求都要求電源側(cè)提供更高的輸入功率，進(jìn)而導(dǎo)致電源容量的大幅增加。在現(xiàn)有供電系統(tǒng)的基礎(chǔ)上，基站電源存在極大的擴容和新建需求。羅湖區(qū)口碑好通信電源通信電源系統(tǒng)在通信系統(tǒng)中占據(jù)十分重要的位置。</p><div style="width:100%;text-align:

style="text-indent:25px">電源是向電子設(shè)備提供功率的裝置，也稱電源供應(yīng)器，它提供計算機中所有部件所需要的電能。電源功率的大小，電流和電壓是否穩(wěn)定，將直接影響計算機的工作性能和使用壽命。計算機電源是一種安裝在主機箱內(nèi)的封閉式**部件，它的作用是將交流電通過一個開關(guān)電源變壓器換為5V，-5V，+12V，-12V，+3.3V等穩(wěn)定的直流電，以供應(yīng)主機箱內(nèi)系統(tǒng)版，軟盤，硬盤驅(qū)動及各種適配器擴展卡等系統(tǒng)部件使用。通俗來講就是，一個電源壞了，另一個備份電源代替其供電?？梢酝ㄟ^為節(jié)點和磁盤提供電池后援來增強硬件的可用性。HP
