A multiple DC control for single power supply, including a power supply unit, a plurality of DC output units and a plurality of control units, and a detection unit. Each control unit is connected between the power supply unit and a corresponding one of the DC output units. Each control unit respectively consists of a protection circuit, a DC ON/OFF control circuit and a DC power control circuit. Thereby, in case of short circuit, poor connection, over-current or other irregularity in any one of the DC output units, the respective control unit in connection will switch off power supply to the DC output unit, without influencing normal operation of other DC output units.
