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。 </p><p
