源装置。 In an uninterruptible power supply that supplies power to a computer system, detects a power outage, and outputs a power failure detection signal, there is a switch that instructs the uninterruptible power supply to turn off the power output, and a switch that instructs the computer system to a control unit that sends a shutdown command prepared in advance;
A line that matches the signal level between this control unit and the serial interface of the computer system.
A driver, a relay that turns off power output to the computer system, and a timer section that is provided in the control section and that issues an off signal to the relay after a certain period of time has elapsed since the shutdown command was sent. An uninterruptible power supply featuring:
