Abstract (en)
[origin: WO9622626A1] An uninterruptible power supply has a power supply housing (11) containing an input for receiving AC utility power, and an AC to DC converter (2) and a switching means (4) for supplying a chopped DC signal to a primary winding (5) of a transformer (6). A pair of secondary windings (7, 8) supply DC power to a pair of regulated DC outputs. The housing (11) also contains a high power FET switch (12) which is connected between one of the secondary windings (6, 7) and a terminal of a connector provided in a wall of the housing (11). An external control module (10) is arranged to be coupled to the connector to complete an auxiliary power supply circuit. When the AC utility power fails, power is coupled from a rechargeable battery, through the control module (10) and the FET switch (12), to the regulated DC outputs of the supply.
