增加電池容量?？梢愿鶕?jù)所需供電的時間長短增加電池的數(shù)量，但是采用這種方法會造成電池充電時間的相對增加，同時也會增加相應的維護設備的數(shù)量、增大產(chǎn)品體積，造成UPS整體成本提高； </p> <p> 選購容量較大的UPS。采用這種方法不僅可以降低維修成本，如果需要擴充負載設備，較大容量的不間斷電源仍可正常工作。 </p> <p> 不間斷電源（UPS）的容量如何計算 </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能夠提從的比較大電流為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設計不佳，在選購UPS時，應考慮功率因數(shù)問題。達州機房**ups不間斷電源價格在線式UPS電源的供電質量明顯優(yōu)于后備式UPS電源。</p><div

市電有時會發(fā)生電壓上涌和下陷或瞬間壓降，這樣的問題會影響設備的精細度，嚴重時會損壞精密設備使用戶遭受損失。UPS系統(tǒng)可以提供穩(wěn)定的電壓，從而保護設備。 </p> <p> 控制橫模和共模噪聲的作用 </p> <p> 橫模噪聲產(chǎn)生在火線與中性線之間;共模噪聲產(chǎn)生在火線、中性線與地線之間。看不見的電力問題防不勝防，時時刻刻危害著儀器設備，給用戶造成損失。UPS電源為儀器和數(shù)據(jù)保駕護航，確保設備的正常運行和延長設備使用壽命。 </p> <p> UPS系統(tǒng)是數(shù)據(jù)中心供電連續(xù)性的重要保障，UPS系統(tǒng)的可靠性直接影響數(shù)據(jù)中心的可靠性，同時，在絕大多數(shù)數(shù)據(jù)中心，UPS系統(tǒng)的損耗可占IT設備能耗的10%以上。因此，提高UPS系統(tǒng)的可靠性，同時降低其損耗，就成為數(shù)據(jù)中心UPS系統(tǒng)架構演變的主旋律。廣元科士達ups不間斷電源廠商</p><p
