PURPOSE:To limit a rush current to prevent the breakdown of a host apparatus by supplying a plurality of subordinate apparatus with main power in order at the time of receiving a control power from the AC output service receptacle of the host apparatus. CONSTITUTION:When the power switch 61 of a host apparatus 4 is turned ON, the host apparatus 4 is started and simultaneously power is supplied by an AC output service receptacle 51 from a control power source 12 to an AC distributor 1. The AC distributor 1 is fitted with a DC stabilized power circuit 2 as a control power source to supply a timer circuit 3 with DC power. When the time circuit 3 starts operation and the time set for a timer is reached, a relay contact 21 is turned ON, a plurality of relay contacts are successively turned ON at equal time intervals, and lastly relay contact 22 is turned ON. Power is successively supplied to subordinate apparatus 5, 6 by output connectors 31, 32 and the system starts operation. Thus, it is possible to limit a rush current to prevent the breakdown of a host apparatus 4. |
