BACKUP POWER SUPPLY AND POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To simplify the configuration of a power transformer, and to easily add backup power supply or replace its components.

SOLUTION: Dimensions and a connector of an AC-DC converter is made to be the same as those of a backup power supply to freely replace the AC-DC converter by the backup power supply. Functions are added which allow a secondary battery to charge a potential accumulating means of a backup power supply output side, and collect information about the current of the AC-DC converter and information about failure thereof, when the backup power supply is inserted.
