UPS帶載過輕（如1000VA的UPS帶100VA負(fù)載）有可能造成電池的深度放電，會(huì)降低電池的使用壽命，應(yīng)盡量避免。 </p> <p> 適當(dāng)?shù)姆烹姡兄陔姵?，如長期不停市電，每隔三個(gè)月應(yīng)人為斷掉市電用UPS帶負(fù)載放電一次，這樣可以延長電池的使用壽命。 </p> <p> 對(duì)于多數(shù)小型UPS，上班再開UPS，開機(jī)時(shí)要避免帶載啟動(dòng)，下班時(shí)應(yīng)關(guān)閉UPS；對(duì)于網(wǎng)絡(luò)機(jī)房的UPS，由于多數(shù)網(wǎng)絡(luò)是24小時(shí)工作的，所以UPS也必須全天候運(yùn)行。 </p> <p> UPS放電后應(yīng)及時(shí)充電，避免電池因過度自放電而損壞。 UPS主機(jī)現(xiàn)場應(yīng)放置操作指南，指導(dǎo)現(xiàn)場操作。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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(dòng)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(shí)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(jià)格便宜,可靠性高等優(yōu)點(diǎn),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(diǎn)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(duì)電力要求苛刻的環(huán)境中; 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。南充愛克賽ups不間斷電源廠商</p><p style="text-indent:25px">在線式UPS電源的供電質(zhì)量明顯優(yōu)于后備式UPS電源。南充愛克賽ups不間斷電源廠商</p><p> 瞬間保護(hù)作用 </p> <p>
