<p>PROBLEM TO BE SOLVED: To provide a control unit with a power supply monitoring function which prevents an encapsulation material that encapsulates a component from being deteriorated by heat that is generated in the component by a failure of a power supply circuit.SOLUTION: A control unit 1a with a power supply monitoring function includes: an electric leakage handling section 10a which inhibits power supply from a commercial power source 2 to a power supply circuit 30 when a current equal to or higher than a predetermined upper limit current flows from the commercial power source 2 to the power supply circuit 30; and a control circuit 50a including power supply monitoring sections 51, 57 and 65 which are encapsulated by an encapsulation material and operated by power supplied from the power supply circuit 30 and by which, when an output voltage of the power supply circuit becomes equal to or higher than an upper limit voltage 15 V that is higher than a rating value, the electric leakage handling section 10a is forcibly operated to inhibit power supply from the commercial power source 2 to the power supply circuit 30.</p> |
