路付電源回路。[Scope of Claim for Utility Model Registration] A starting circuit that rectifies AC input through a rectifier and a capacitor, supplies power to a DC/DC converter, and inserts a starting resistor at startup to reduce inrush current, and then short-circuits the starting resistor. In the provided power supply circuit, a capacitor voltage monitoring circuit consisting of a resistor, a constant voltage diode, and a light emitting diode coupler is provided in parallel with the capacitor, and a failure of the starting resistor is detected depending on whether or not the light emitting diode coupler of the capacitor voltage monitoring circuit is lit. A power supply circuit with a starting circuit characterized by detecting the presence or absence of the power supply circuit.
