Abstract
This power supply device (100) is provided with a power supply unit (10), a temperature sensor (28) for measuring the internal temperature of the power supply unit (10), a calculation circuit (22) for predicting an end-point temperature from the internal temperature of the power supply unit (10) measured by the temperature sensor (28) and the slope of the internal temperature rise and estimating a surrounding temperature on the basis of the end-point temperature and the load status of the power supply unit (10); and a display circuit (23) for displaying the surrounding temperature estimated by the calculation circuit (22).
