Abstract
A power supply device includes a first circuit, a second circuit and a second detector. The first circuit includes an adjustment unit, a first controller which controls the adjustment unit, a first detector which detects a parameter about electric power supplied to a load, a first communication unit. The second circuit includes a second communication unit which performs wireless communication with the first communication unit and a second controller. The second detector detects a temperature of the load. The first controller is operated by electric power supplied thereto by a voltage output to the second communication unit. The first communication unit transmits information about a result of detection by the first detector to the second communication unit. The second controller controls the first controller via the first communication unit and the second communication unit based on the information. In a case where the temperature is higher than a predetermined temperature, supplying of the electric power is blocked off.
