PURPOSE:To suppress power consumption efficiently according to mission by additionally providing an overcurrent protective circuit for turning an output line OFF to each output line at load side while furthermore providing a power source stabilizing circuit and disconnecting the output line selectively for unnecessary mission. CONSTITUTION:A power source equipment used in space comprises a plurality of overcurrent protective circuits 6-1 to 6-n connected with respective output source lines on the load side and disconnecting a load from each output source line upon occurrence of overcurrent, an external interface circuit 7 for receiving external control signals necessary for selective function of the plurality of overcurrent protective circuits 6-1 to 6-n, a plurality of stabilizing circuits 8-1 to 8-n connected between the protective circuits 6-1 to 6-n and loads 9-1 to 9-n in order to stabilize fluctuation of power source due to selective function of the protective circuits 6-1 to 6-n, and the like. By such arrangement, power consumption can be suppressed efficiently according to the mission of space flying object. |
