PROBLEM TO BE SOLVED: To provide a power unit for effectively suppressing a rush current when a power source is turned on concerning the power unit having a commercial transformer. SOLUTION: Concerning the power unit which is provided with a commercial transformer T equipped with two output systems and respectively connects loads to the respective output systems, this unit has ON/OFF circuits 1 and 2 for turning on/off the respective output systems connected to these respective two output systems and an ON/OFF control circuit 9 for driving the ON/OFF circuits 1 and 2 of respective output systems to asynchronously turn them on. Thus, the rush currents caused by respective loads are prevented from simultaneously flowing. |
