Document Type and Number:
Japanese Patent JP6330781
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To help determine necessity for reuse of a power source substrate or a component interchange by notifying information on a lifetime of each photocoupler on the basis of an actual lighting sate of a light emitting element.SOLUTION: A power lifetime determination device includes: a notification unit; a power source substrate that includes a controller controlling a switching element to adjust an output voltage, a light emitting element and a light reception element, in which the light reception element includes a plurality of photocouplers to be connected to the controller; a time counting unit that counts a lighting time of each light emitting element; a storage unit that stores a cumulative lighting time of each light emitting element; an operation panel that receives a lifetime determination execution instruction of the photocoupler; and a control unit that decides a lighting possible time of each light emitting element, subtracts the corresponding cumulative lighting time from the lighting possible time, obtains an estimation residual time until the lifetime of each photocoupler goes dead, and causes the notification unit to notify each estimation residual time as a lifetime determination result.SELECTED DRAWING: Figure 7
