PURPOSE:To ensure safety for a power supply having an output voltage setting switch by providing a protector for preventing supply of incorrect output voltage thereby interrupting output voltage supply when a target output voltage is not set. CONSTITUTION:A power supply 21 is provided with a device connector 21c to be connected with an external connector 21d, a section 21b comparing a signal for selecting an output voltage from a switch 21a for setting an output voltage with a signal for confirming the output voltage to be set from the device connector 21c to control the output of power supply only when the signals match each other, and means for receiving an output signal from the section 21b and interrupting the output voltage from the power supply 21. |
