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(hù)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(jī)、外設(shè)、POS機(jī)等領(lǐng)域; </p> <p> 在線式UPS結(jié)構(gòu)較復(fù)雜,但性能完善，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,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; 張家界機(jī)房ups不間斷電源UPS

UPS中文為“不間斷電源”。是一種含儲能裝置，以整流器、逆變器為主要組成部分，為變電站內(nèi)監(jiān)控系統(tǒng)、自動化儀表、遠(yuǎn)方通信系統(tǒng)等設(shè)備提供恒壓恒頻的不間斷電源。 </p> <p> UPS系統(tǒng)的主要作用有兩方面： </p> <p> 做為重要設(shè)備的交流供電電源，防止市電突然斷電而影響正常工作，給設(shè)備造成損害； </p> <p> 消除市電中的電涌、瞬間高/低電壓、電線噪聲和頻率偏移等“電源污染”，改善電源質(zhì)量，為計算機(jī)等提供高質(zhì)量的電源。 </p> <p> UPS系統(tǒng)主要有有三種類型：后備式、互動式、在線式。因為UPS裝了防雷充其量只能使配電柜中省一級防雷，但是配電當(dāng)中還是不能省略防雷裝置。張家界機(jī)房ups不間斷電源</p><p
