Abstract

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.
