UPS的電性能指標(biāo)有基本電性能(如輸入電壓范圍、穩(wěn)壓率、轉(zhuǎn)換時(shí)間等)、認(rèn)證性能(如安全認(rèn)證、電磁干擾認(rèn)證)、外觀尺寸等。依輸出電壓波形在市電斷電時(shí)是否具有轉(zhuǎn)換時(shí)間，可將UPS分類為后備式(Off Line，有轉(zhuǎn)換時(shí)間)與在線式(On Line，無轉(zhuǎn)換時(shí)間)兩種。在線互動(dòng)式(Line Interactive)由于仍有轉(zhuǎn)換時(shí)間，因此被視為是后備式的一種變型，只是充電時(shí)間較后備式的短而已。后備式與在線式UPS的另一個(gè)主要區(qū)別是穩(wěn)壓率，在線式的穩(wěn)壓率一般在2%以內(nèi)，而后備式至少在5%以上。因此，若用戶的負(fù)載設(shè)備屬高階通訊設(shè)備、醫(yī)療儀器、微波接收設(shè)備時(shí)，以選擇在線式UPS較佳。</p><p style="text-indent:25px">UPS電源就是不間斷電源，當(dāng)正常交流供電中斷時(shí)，將蓄電池輸出的直流變換成交流持續(xù)供電的電源設(shè)備。主要用于給單臺(tái)計(jì)算機(jī)、計(jì)算機(jī)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(dāng)市電輸入正常時(shí)，UPS 將市電穩(wěn)壓后供應(yīng)給負(fù)載使用，此時(shí)的UPS就是一臺(tái)交流市電穩(wěn)壓器，同時(shí)它還向機(jī)內(nèi)電池充電;當(dāng)市電中斷(事故停電)時(shí)， UPS 立即將機(jī)內(nèi)電池的電能，通過逆變轉(zhuǎn)換的方法向負(fù)載繼續(xù)供應(yīng)220V交流電，使負(fù)載維持正常工作并保護(hù)負(fù)載軟、硬件不受損壞。UPS 設(shè)備通常對(duì)電壓過大和電壓太低都提供保護(hù)。UPS不間斷電源它可以實(shí)現(xiàn)對(duì)負(fù)載的穩(wěn)頻、穩(wěn)壓供電，且在由市電供電轉(zhuǎn)換到蓄電池供電時(shí)，其轉(zhuǎn)換時(shí)間為零。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">在線式UPS輸出正弦波的波形失真系數(shù)較小，一般小于3%。市電中斷時(shí)在線式UPS能真正實(shí)現(xiàn)對(duì)負(fù)載的不間斷供電。只要機(jī)內(nèi)蓄電池能向UPS逆變器提供能量，無論市電是否中斷，在線式UPS都是由逆變器向負(fù)載供電。因此，從市電供電到市電中斷的過程中，在線式UPS內(nèi)部并沒有產(chǎn)生任何轉(zhuǎn)換動(dòng)作，其對(duì)負(fù)載供電的轉(zhuǎn)換時(shí)間為零。在線式UPS同后備式UPS相比，具有優(yōu)良的輸出電壓瞬變特性。一般在l00%負(fù)載加載或99%負(fù)載減載時(shí)，它的輸出電壓變化范圍為1%左右，這種變化的持續(xù)時(shí)間一般為1~3周波。在線式UPS一般采用20kHz以上的PWM技術(shù)，其噪聲較小，約為50dB。在線式UPS的控制電路中，采用輸入變壓器、輸出變壓器及光電耦合器件等將“強(qiáng)電”驅(qū)動(dòng)部分與“弱電”控制線路部分從電的角度隔離開來，因而電路的可靠性得到了極大的提高。這種UPS的故障率一般都很低。UPS不間斷電源性能完善，能解決解決尖峰、浪涌、頻率漂移等多種電源問題。合肥大功率UPS不間斷電源價(jià)格</p><p
