A power supply which can individually limit the discharge current and the absorbing current as the output current supplied to the load is disclosed. The power supply comprises an amplification circuit for amplifying and supplying an analog voltage value to the load; a limited current switching circuit, connected to a current limiting control terminal of the amplification circuit, for changing the amount of a limited current which controls the output current of the amplification circuit; and a switching control circuit for outputting a switching signal by which the limited current switching circuit changes the amount of the limited current.
