| description | The utility model belongs to the field of electricity, and particularly relates to a direct-current power supply overheating protection circuit. The design of the direct-current power supply not only needs to use electronic elements with good high-temperature characteristics, but also needs reasonable design, advanced printed circuit board (PCB) and radiator production process and an overheat protection circuit. The device comprises a temperature relay, an auxiliary power supply VCC, a current-limiting resistor R1 and an execution circuit. The execution circuit is connected with a temperature relay KT1 through a resistor R1; the temperature relay KT1 is connected with the auxiliary power supply VCC, the current-limiting resistor R1 and the filter capacitor C1 are connected in parallel to form an RC filter circuit, and the filter capacitor C1 is grounded. The utility model provides a circuit capable of flexibly and reliably completing an overheat protection function for a direct current power supply.
