PROBLEM TO BE SOLVED: To suppress the cost penalty or malfunction of electronic equipment and to stably operate a DC stabilizing power source. SOLUTION: A multi-output power supplying device 1 is provided with a 1st output system for always outputting DC power while dividing the DC output of a DC stabilizing power source 10 into systems more than two and plural 2nd output systems for turning on/off the DC output according to a control signal from the outside (load 9a) and at the same time, an integration circuit 3 of the 2nd output system envelopes the rise and fall of the control signal. Then, a switch circuit 4 smoothly turns on or off the DC output of the 2nd output system according to the output of the integration circuit 3. At such a time, in order to supply the DC outputs of the respective 2nd output systems to plural loads 9b, 9c...9n in required order, control signals for turning on/off the correspondent switch circuits 4 are impressed from a sequence control circuit 5 to the respective integration circuits 3 of the respective 2nd output systems in that required order. |
