style="font-size:12px;">UPS不間斷電源自1903年在美國洛杉磯問世之后，迅速在當時的重工業(yè)中得到了的應用。我們國內(nèi)自主生產(chǎn)的UPS不間斷電源是在1978年下線，1979年中美建交，我國回送給美國大使的禮物就是我國自己研發(fā)的UPS，當時引起一片轟動。隨著生產(chǎn)生活的進步，用電需求的日益增長，UPS電源在國內(nèi)的企業(yè)和家庭中受到了越來越大的重視和使用，特別是互聯(lián)網(wǎng)的高速發(fā)展，電腦服務器等各種電子設備對用電要求越來越高，UPS也發(fā)揮了越來越大的作用。國內(nèi)UPS電源的使用客戶已經(jīng)超過了2億，業(yè)內(nèi)營業(yè)額達到了驚人的500多億元。</span> 電源市場風起云涌，競爭日趨激烈，對于電子工程師，電源似乎已成一個隨處抓一模塊都可以滿足要求的時代。燈桿電-源哪家好</p><p style="text-indent:25px">帶NB卡功能，基于OneNET平臺，實現(xiàn)對市政設備的遠程集中控制與管理。上海智能電-源***選擇</p><p style="text-indent:25px">負載的類型也是一個影響因素。一般的模塊，其輸出是按照默認為阻性負載而設計的，如果負載是感性或容性負載，都需要做電源模塊內(nèi)部器件或參數(shù)稍作調(diào)整。電源模塊的開關頻率也是需要關注的，他決定了外接電源濾波器濾波參數(shù)(截止頻率、階次)的選擇。紋波與拓撲結(jié)構(gòu)、電容電感的參數(shù)、負載的情況都相關，一個5v電源，紋波做到50mv，單電源的誤差就是1%了，對精度要求高的電路，電源的誤差、放大電路的誤差、信號電纜的誤差、AD的舍入誤差，多個誤差累積合并之后，總誤差可就大了。電源模塊里有無濾波設計、電源模塊所在的設備里有無安規(guī)要求(漏電流、絕緣耐壓、濕度要求)、溫升特性、轉(zhuǎn)換效率、輸入電壓的波動范圍、負載調(diào)整率等等，要求的地方還是不少的。上海智能電-源***選擇</p><p
