制御装置の電源装置。[Claims for Utility Model Registration] Power is applied to a control device that stores identification information for identifying its own power save state, and a RAM write inhibit signal, an operation stop signal, and a reset signal are derived to the control device. In the power supply device, when the RAM write inhibit signal and the operation stop signal are input, the identification information of the control device is forced into a power save state, and the power supply device detects the voltage level supplied to the control device and sets the predetermined voltage level. Comparing the voltage level with a third setting level that generates a RAM write inhibit signal, comparing the voltage level with a first setting level that generates the operation stop signal determined in advance, and further generating the reset signal. A second set level to be generated is compared with the voltage level, and a control device is controlled based on the result,
The first setting level and the second setting level are chosen equally, and the third setting level is equal to the first setting level and the second setting level.
A power supply device for a control device, characterized in that the level is selected higher than a set level.
