US 2015/0316968 A1 · POWER SUPPLY

Abstract

A power supply includes a circuit board, a cable assembly, a voltage conversion component, and a DC voltage conversion component. The circuit board includes a connector. The cable assembly, the voltage conversion component, and the DC voltage conversion component are electrically connected to the circuit board. The cable assembly includes an external connector configured to connect to a peripheral circuit. The voltage conversion component can convert an AC voltage to a first DC voltage. The DC voltage conversion component can convert the first DC voltage to a second DC voltage. The power supply further includes a DC voltage conversion card to convert the second DC voltage to a third DC voltage. The cable assembly outputs the third DC voltage when the DC voltage conversion card is engaged with the connector, and the cable assembly outputs the second DC voltage when the DC voltage conversion card is disengaged from the connector.
