Claim:
1. A power supply unit including a power source and a plurality of loads receiving power from the power source, the power supply unit comprising: a branching circuit branching one power line connected to the power source into a plurality of branch lines for providing the plurality of loads with power source line, the branching circuit being located adjacent to the loads; and a connector including a connector housing, a first terminal fitting , and a plurality of second terminal fittings, the first terminal fitting being connected to the power source, the plurality of second terminal fittings being connected to the loads, the branching circuit being housed in the connector housing, in connection with the first terminal fitting and the second terminal fittings, wherein the connector housing further houses a plurality of switching elements each disposed on the branch lines, a voltage detector detecting a supply voltage supplied to each of the loads inputted from the first terminal fitting, and an on/off controller intermittently switching on the switch elements and decreasing a duty ratio of an on-period of the switching elements as the supply voltage detected by the voltage detector rises.
