The AD-55B is a buffer switch mode power supply with a separate charging circuit. This type of device is a good solution for a backup power supply system. In the event of a power outage, the product begins to provide power from the connected battery (battery not included, must be purchased separately).  Thanks to this, in the event of a failure, you can provide power supply even for a long time (the duration depends on the battery).
