摘要： An energization control system includes a sensor unit including a magnetic detection portion detecting a magnetic flux density of a magnetic flux generated at a surrounding of a conductor in response to a current flowing in the conductor of an electrical apparatus, a temperature detection portion detecting a temperature level within a package in which the magnetic detection portion is disposed, a correction portion correcting a temperature characteristic of a detection result of the magnetic detection portion based on the detected temperature level, and an output portion outputting temperature information indicating the detected temperature level. The energization control system further includes a control unit including a control portion controlling a current flowing in a heating element of the electrical apparatus based on the temperature information.
