徴とする電源保護装置。 In a power supply device that commonly supplies a single power source to a load group consisting of multiple devices, a current limiting means detects an overcurrent of the load and limits the output current, and when the current limiting means detects an overcurrent. A power protection means is installed separately in front of each of the plurality of devices described above, and includes a comparison means for comparing the obtained voltage with a reference voltage, and a switch control means for controlling opening/closing of the power supplied to the load based on the comparison result of the comparison means. A power protection device characterized in that it is connected.
