UPS能在電力異常時有足夠的時間實(shí)施應(yīng)急措施。一般而言5-10分鐘的后備時間就足夠了。如果需要較長的后備時間，可以購買具有長延時功能的UPS。 </p> <p> 不間斷電源的容量如何計(jì)算 </p> <p> 目前市場上銷售的不間斷電源（UPS）多以VA作為容量單位。V是電壓，A是電流，V×A就等于功率，即不間斷電源的容量。例如，一臺425VA的不間斷電源，如果其輸出電壓為110V，則該UPS能夠提供的比較大電流為3.86A，超過此電流值就是超載（Overload）。另一種表示功率的方法是W，W表示實(shí)功，VA表示虛功。兩者之間的差別在于功率因數(shù)。功率因數(shù)一般在為0.6到0.8之間，若低于0.5則UPS設(shè)計(jì)不佳，在選購UPS時，應(yīng)考慮功率因數(shù)問題。 </p><p> UPS作為保護(hù)性的電源設(shè)備，它的性能參數(shù)具有重要意義，應(yīng)是我們選購時的考慮重點(diǎn)。市電電壓輸入范圍寬，則表明對市電的利用能力強(qiáng)（減少電池放電）。輸出電壓、頻率范圍小，則表明對市電調(diào)整能力強(qiáng)，輸出穩(wěn)定。波形畸變率用以衡量輸出電壓波形的穩(wěn)定性,而電壓穩(wěn)定度則說明當(dāng)UPS突然由零負(fù)載加到滿負(fù)載時，輸出電壓的穩(wěn)定性。 </p> <p> 還有UPS效率、功率因數(shù)、轉(zhuǎn)換時間等都是表征UPS性能的重要參數(shù)，決定了對負(fù)載的保護(hù)能力和對市電的利用率。性能越好，保護(hù)能力也越強(qiáng)，總的來說，離線式UPS對負(fù)載的保護(hù)很差，在線互動式略優(yōu)之，在線式則幾乎可以解決所有的常見電力問題。當(dāng)然成本也隨著性能的增強(qiáng)而上升。因此用戶在選購UPS時，應(yīng)根據(jù)負(fù)載對電力的要求程度及負(fù)載的重要性不同,而選取不同類型的UPS。 UPS在機(jī)房工程中重要設(shè)備，它能保證正常市電中斷后為弱電系統(tǒng)提供有效的電力保障。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州伊頓ups不間斷電源報(bào)價,ups不間斷電源"
