我們很常用的是后備式UPS,如四通HO系列與SD系列，它具備了自動穩(wěn)壓、斷電保護等UPS很基礎(chǔ)也很重要的功能，雖然一般有10ms左右的轉(zhuǎn)換時間，逆變輸出的交流電是方波而非正弦波,但由于結(jié)構(gòu)簡單而具有價格便宜,可靠性高等優(yōu)點,因此廣泛應(yīng)用于微機、外設(shè)、POS機等領(lǐng)域; </p> <p> 在線式UPS結(jié)構(gòu)較復(fù)雜,但性能完善，云南機房ups不間斷電源廠商，能解決所有電源問題，如四通PS系列，其明顯特點是能夠持續(xù)零中斷地輸出純凈正弦波交流電，云南機房ups不間斷電源廠商，云南機房ups不間斷電源廠商,能夠解決尖峰、浪涌、頻率漂移等全部的電源問題;由于需要較大的投資,通常應(yīng)用在關(guān)鍵設(shè)備與網(wǎng)絡(luò)中心等對電力要求苛刻的環(huán)境中; 互動式：具有濾波功能，抗市電干擾能力強，轉(zhuǎn)換時間小于4ms，逆變輸出為模擬正弦波，價格遠低于在線式；云南機房ups不間斷電源廠商</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="云南機房ups不間斷電源廠商,ups不間斷電源"

LBS的作用是將兩組UPS同步，目的是為了使STS的切換時間為零。 </p> <p> 雙總線的作用是為了給用電設(shè)備提供冗余的電源。 </p> <p> EPS和在線式UPS的主要區(qū)別是什么？兩者的主要用途是什么？ </p> <p> 與UPS相同之處：EPS是***的后備式UPS，它的工作原理和后備式UPS一樣。 </p> <p> 不同之處：EPS由于帶的負載不同，比如照明和啟動水泵等，功率需要做的很大，在啟動水泵時可以將逆變器做成變頻器；而后備式UPS由于主要的對象是PC機之類的IT設(shè)備，所以容量很少有超過3KVA的。云南機房ups不間斷電源廠商后備式：具備自動穩(wěn)壓、斷電保護等功能，轉(zhuǎn)換時間10ms左右，逆變輸出的交流電是方波，結(jié)構(gòu)簡單，價格便宜；</p><div

不間斷電源，是一種含有儲能裝置，以逆變器為主要組成部分的恒壓恒頻的不間斷電源。主要用于給單臺計算機、計算機網(wǎng)絡(luò)系統(tǒng)或其它電力電子設(shè)備提供不間斷的電力供應(yīng)。當市電輸入正常時，UPS不間斷電源將市電穩(wěn)壓后供應(yīng)給負載使用，此時的UPS就是一臺交流市電穩(wěn)壓器，同時它還向機內(nèi)電池充電；當市電中斷（故障停電）時，UPS立即將機內(nèi)電池的電能，通過逆變轉(zhuǎn)換的方法向負載繼續(xù)供應(yīng)220V交流電，使負載維持正常工作并保護負載軟、硬件不受損壞，UPS不間斷電源設(shè)備通常對電壓過大和電壓太低都提供保護。云南機房ups不間斷電源廠商</p><p
