    UPS = Uninterruptible Power Supply

    分 Online UPS / OFF Line UPS

    先講Online UPS

    Utility Power ON ---> Regulated /Rectifier /Charger ---> Battery And Inverter

    --> Transfer Switch ---> Loading

    如果"Utility Power" OFF

    Battery ---> Inverter ----> Transfer Switch---> Loading

    (供電冇間斷)

    OFF Line UPS

    Loading 接駁到 Transfer Switch的Utility Power ,如果停電再轉回電池供電.

    (供電有間斷)
