Title:
OUTPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/084225
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an output device with which the impact of a voltage supply fault on an output subject can be reduced even when the fault occurs in the continuous supply of voltage by an output unit. To solve this problem this output device is equipped with a first output unit, a determination unit, a power storage unit, and a second output unit. The first output unit outputs a first DC voltage from an output terminal. The determination unit outputs a prescribed notification when the first DC voltage is less than a prescribed threshold value. The power storage unit is arranged between the output terminal and a ground, and when the first DC voltage falls below the threshold value the power storage unit outputs to the output terminal a DC voltage equal to or greater than the threshold value, by means of power stored when the first DC voltage is equal to or greater than the threshold value. When the notification is input, the second output unit outputs from the output terminal a second DC voltage equal to or greater than the threshold value.
