Power supplying equipment



PROBLEM TO BE SOLVED: To provide a power supplying equipment capable of being miniaturized and reduced in weight and switching powers, without causing power cut-off. SOLUTION: This power supplying equipment is provided with a voltage measuring section 2 for measuring voltages of specified power and the other powers, which are input independently, separately, a power selecting section 3 for selecting a power which has a voltage level required by a load or higher, as operating power from the powers detected by the voltage measuring section 2 and outputting it to a load, a voltage dropping section 5, which when the power selected by the power selecting section 3 is the specified power, drops the other powers to a voltage level which is lower than that of the specified power and then outputs the dropped powers to the output side of the power selecting section 3, a switching section 7 for switching the power output to the load to either a cut-off state or an output state, and a supply state holding section 7b which keeps a re-input state in a cut-off state after a non-input state in which the inputs, including the specified power and the other powers, have all stopped in the cut-off state.
