style="font-size:12px;">線性穩(wěn)定電源有一個共同的特點就是它的功率器件調(diào)整管工作在線性區(qū)，靠調(diào)整管之間的電壓降來穩(wěn)定輸出。由于調(diào)整管靜態(tài)損耗大，需要安裝一個很大的散熱器給它散熱。而且由于變壓器工作在工頻（50Hz)上,所以重量較大。</span><span style="font-size:12px;">該類電源優(yōu)點是穩(wěn)定性高，紋波小，可靠性高，易做成多路，輸出連續(xù)可調(diào)的成品。缺點是體積大、較笨重、效率相對較低。這類穩(wěn)定電源又有很多種，從輸出性質(zhì)可分為穩(wěn)壓電源和穩(wěn)流電源及集穩(wěn)壓、穩(wěn)流于一身的穩(wěn)壓穩(wěn)流（雙穩(wěn)）電源。從輸出值來看可分定點輸出電源、波段開關(guān)調(diào)整式和電位器連續(xù)可調(diào)式幾種。從輸出指示上可分指針指示型和數(shù)字顯示式型等等。</span>

就和其它傳統(tǒng)行業(yè)一樣，UPS行業(yè)也遇到了競爭加劇和產(chǎn)業(yè)升級的壓力：產(chǎn)品功能同質(zhì)化嚴重，各種山寨劣質(zhì)產(chǎn)品層出不窮，為了追求市場，不斷壓低產(chǎn)品銷售價格，而為了尋求利潤空間，就不得不控制成本，偷工減料，降低產(chǎn)品質(zhì)量。這種惡性競爭的后果就是忽視了客戶的需求，**終的結(jié)果還是傷害整個行業(yè)。<span style="font-size:12px;">這幾年國內(nèi)的UPS企業(yè)也在不斷的需求改變和突破，比如現(xiàn)在已經(jīng)成為主流的液晶屏顯示，也是UPS行業(yè)求變的結(jié)果。</span><span style="font-size:12px;">但是，用戶對UPS電源的真實需求在哪里?這是我們一直在琢磨和考慮的問題。</span>
