Abstract
A universal power transformer (101) is for connection to an AC power source and produces a regulated DC voltage at an output thereof. The power transformer includes a power transformer housing (102) with a recess (114). A universal power converter circuit (313) is positioned in the housing. Connector prongs (108, 110) are electrically coupled to the circuit and are movably carried on the housing at a position adjacent the recess. The prongs move between an outwardly extending position, projecting from the housing for connection to a first type of power supply connector, and a retracted position, extending into the recess for storage during transport of the power transformer and for connection to an adapter (103-106) positioned in the recess, to connect to a second type of power supply connector.
