<p>PURPOSE:To reduce the man-hour of system design, by monitoring the rush current of the system and determining automatically intervals of power supply to each device on a basis of this value. CONSTITUTION:An electric current detecting circuit 15 is provided on a power line 13, and a current value information signal line 16 which sends the output of the current detecting circuit 15 to a power supply controller 12 is provided. Electric power is sent from a power source 11 for system to devices 1-(n) through the power line 13. First, the power supply controller 12 sends a power- on command signal to the device 1 through a power supply control signal line 14 to turn on the device 1. Simultaneously, the rush current is detected by the current detecting circuit 15; and when the rush current is lowered to a prescribed value, the device 2 is turned on similarly. Devices are turned on similarly hereafter up to the device (n) to terminate the power supply to the system.</p> |
