PROBLEM TO BE SOLVED: To provide power supply with many outputs which can reduce standby power using simple constitution. SOLUTION: This power supply is provided with an output current detecting circuit 12 for detecting the load current, supplied to a load 8 which needs power on a steady basis, and a relay 14 which is subjected to on/off control, on the basis of an output signal of the detecting circuit 12. When the load current is smaller than a prescribed value, the relay 14 turns to off-state, thereby eliminating the standby power of an output system (output system connected with a load 9), except an output system which is connected to the load 8, which needs the stationary power on a steady basis. |
