UPS電(dian)(dian)(dian)(dian)(dian)源即不間(jian)斷電(dian)(dian)(dian)(dian)(dian)源，是將蓄(xu)電(dian)(dian)(dian)(dian)(dian)池與主機相連接，通過(guo)主機逆變器(qi)等模塊(kuai)電(dian)(dian)(dian)(dian)(dian)路將直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)轉換(huan)(huan)成市電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)系統設備。主要(yao)(yao)用(yong)于(yu)(yu)給單臺(tai)計(ji)算機、計(ji)算機網(wang)絡系統或(huo)其(qi)它電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)子設備如(ru)電(dian)(dian)(dian)(dian)(dian)磁閥(fa)、壓力(li)變送器(qi)等提(ti)供(gong)穩定、不間(jian)斷的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)力(li)供(gong)應。UPS電(dian)(dian)(dian)(dian)(dian)源作(zuo)(zuo)用(yong)有一(yi)個濾(lv)波(bo)的(de)(de)(de)作(zuo)(zuo)用(yong)，這個作(zuo)(zuo)用(yong)在我們的(de)(de)(de)實驗(yan)室效(xiao)果為明顯了(le)，比如(ru)正在實驗(yan)過(guo)程中，經常遇到因(yin)電(dian)(dian)(dian)(dian)(dian)磁干(gan)擾(rao)而使(shi)實驗(yan)無(wu)法進行，或(huo)使(shi)儀器(qi)不能(neng)正常運轉，所以消除(chu)干(gan)擾(rao)是個重(zhong)要(yao)(yao)的(de)(de)(de)問題。頻率(lv)變換(huan)(huan)作(zuo)(zuo)用(yong)：輸入頻率(lv)等于(yu)(yu)或(huo)不等于(yu)(yu)輸出頻率(lv)，如(ru)50Hz/50Hz，50Hz/60Hz，包括穩頻作(zuo)(zuo)用(yong);提(ti)供(gong)一(yi)定的(de)(de)(de)后備時間(jian)：UPS的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池貯存一(yi)定的(de)(de)(de)能(neng)量，在電(dian)(dian)(dian)(dian)(dian)網(wang)停電(dian)(dian)(dian)(dian)(dian)或(huo)間(jian)斷時繼續供(gong)電(dian)(dian)(dian)(dian)(dian)一(yi)段時間(jian)來保護(hu)負載。

在(zai)線式(shi)UPS結(jie)構較復雜，但性能(neng)完善，能(neng)解(jie)(jie)決所有電(dian)源(yuan)(yuan)問(wen)(wen)題，如(ru)四(si)通PS系列，其顯(xian)著特點是能(neng)夠(gou)持續零(ling)中斷地輸(shu)出(chu)純(chun)凈(jing)正弦(xian)波交流(liu)(liu)(liu)電(dian)，能(neng)夠(gou)解(jie)(jie)決尖峰、浪涌、頻率(lv)漂移等全部的電(dian)源(yuan)(yuan)問(wen)(wen)題。而我們的UPS電(dian)源(yuan)(yuan)他(ta)自(zi)身可以(yi)自(zi)動抗干(gan)擾，從輸(shu)入端(duan)帶來的干(gan)擾直(zhi)接(jie)(jie)(jie)過(guo)濾(lv)掉，輸(shu)出(chu)端(duan)就成(cheng)了(le)(le)高質量的純(chun)凈(jing)電(dian)源(yuan)(yuan)了(le)(le)。UPS電(dian)源(yuan)(yuan)作用(yong)(yong)的這個方面大大的保護我們的儀器(qi)了(le)(le)。UPS電(dian)源(yuan)(yuan)和普通的電(dian)池(chi)不一樣，因為電(dian)池(chi)產品供電(dian)主要是直(zhi)接(jie)(jie)(jie)使(shi)(shi)用(yong)(yong)直(zhi)流(liu)(liu)(liu)電(dian)腦(nao)，ups不間(jian)斷電(dian)源(yuan)(yuan)，比如(ru)筆(bi)記本上使(shi)(shi)用(yong)(yong)的電(dian)充(chong)是經過(guo)交流(liu)(liu)(liu)電(dian)轉換成(cheng)主流(liu)(liu)(liu)，然(ran)后充(chong)入電(dian)池(chi)內部存儲(chu)(chu)，使(shi)(shi)用(yong)(yong)的時(shi)候是直(zhi)接(jie)(jie)(jie)使(shi)(shi)用(yong)(yong)直(zhi)流(liu)(liu)(liu)電(dian)。但UPS不同(tong)，UPS供電(dian)模式(shi)為先將交流(liu)(liu)(liu)電(dian)轉換成(cheng)直(zhi)流(liu)(liu)(liu)，然(ran)后存儲(chu)(chu)在(zai)儲(chu)(chu)能(neng)設備中，但用(yong)(yong)的時(shi)候它(ta)又是將直(zhi)流(liu)(liu)(liu)電(dian)轉換成(cheng)交流(liu)(liu)(liu)電(dian)直(zhi)接(jie)(jie)(jie)供設備使(shi)(shi)用(yong)(yong)，不了(le)(le)解(jie)(jie)電(dian)源(yuan)(yuan)原理(li)或者不熟悉電(dian)子(zi)產品的朋(peng)友可能(neng)不怎么了(le)(le)解(jie)(jie)，不過(guo)我們只要知道它(ta)不同(tong)于一般電(dian)池(chi)原理(li)即可，但功能(neng)相(xiang)似。

UPS電源大的(de)(de)(de)(de)作用(yong)就(jiu)是(shi)(shi)在(zai)(zai)交(jiao)流電源中(zhong)斷后，仍(reng)然可(ke)以保持給負(fu)載供(gong)電一(yi)段時(shi)(shi)間，以避免(mian)重要(yao)(yao)文件未存檔，或重要(yao)(yao)的(de)(de)(de)(de)服務器因(yin)(yin)(yin)突然掉電而(er)關機。UPS電源無論(lun)是(shi)(shi)在(zai)(zai)減小體(ti)積和重量，降低(di)整體(ti)制(zhi)造工藝成本上，還是(shi)(shi)在(zai)(zai)遏制(zhi)噪音(yin)等方面，其作用(yong)效果都(dou)要(yao)(yao)更為(wei)顯著，因(yin)(yin)(yin)此受到(dao)眾多消費者(zhe)的(de)(de)(de)(de)喜(xi)愛與選擇(ze)。UPS電源作用(yong)有一(yi)個(ge)濾波的(de)(de)(de)(de)作用(yong)，這個(ge)作用(yong)在(zai)(zai)我們的(de)(de)(de)(de)實驗(yan)室(shi)效果為(wei)明顯了，比如(ru)正在(zai)(zai)實驗(yan)過(guo)程中(zhong)，經常遇到(dao)因(yin)(yin)(yin)電磁(ci)干擾而(er)使實驗(yan)無法進(jin)行，或使儀器不能正常運轉(zhuan)，所以消除干擾是(shi)(shi)個(ge)重要(yao)(yao)的(de)(de)(de)(de)問(wen)題。ups電源使用(yong)時(shi)(shi)的(de)(de)(de)(de)注意事項：UPS的(de)(de)(de)(de)使用(yong)環境應(ying)注意通風良(liang)好，利于散熱，并(bing)保持環境的(de)(de)(de)(de)清潔。切勿(wu)帶感性負(fu)載，如(ru)點鈔機、日光燈、空調(diao)等，以免(mian)造成損壞。UPS的(de)(de)(de)(de)輸出負(fu)載控制(zhi)在(zai)(zai)60%左右為(wei)佳(jia)，可(ke)靠性好。
