制御装置。[Scope of claim for utility model registration] An uninterruptible power supply that receives a commercial AC power supply as input, a CPU power supply power supply that receives power from this uninterruptible power supply, and a CPU that receives power from this CPU power supply power supply. , has two opening/closing contacts, one contact is connected between the terminal for controlling the operation of the power supply for supplying CPU power and the ground, and the other contact is connected between the two terminals for controlling the operation of the uninterruptible power supply. is,
Equipped with a power switch that both contacts are open when the power is turned on, and both contacts are closed when the power is turned off, and when the power switch is turned on, the uninterruptible power supply and the CP
In a power supply control device configured such that the power source 2 for supplying power to the CPU is activated and stopped when turned off, one contact 5a is connected to the power source 2 for supplying power to the CPU.
The other contact 5b is connected in series with the contact 4b of the power switch 4 between the operation control terminals A and B of the uninterruptible power supply 3. It is equipped with a relay switch 5 having interlocking contacts, and a driver 6 that drives the relay switch 5 based on a signal from the CPU 1.
The PU 1 is configured to be able to give a drive signal to the driver 6 based on the state signal of the common connection point between the contacts 5a and 4a, and when the power switch 4 is turned on, the CP
When the U power supply power supply 2 and the uninterruptible power supply 3 are activated and the power switch 4 is turned off, the CPU 1 executes the shutdown sequence and then activates the relay switch 5 based on the status signal to activate the CPU power supply power supply. 2 and an uninterruptible power supply 3 are stopped.
