| This power supply is used to supply power, but also to charge and maintain the charged battery. It can be operated, subject to the conditions described below, with all Unipi units and other selected Unipi equipment. In the event of a mains power failure, the power supply switches seamlessly to battery power mode. This achieves an uninterruptible power supply. | This power supply is used to supply power, but also to charge and maintain the charged battery.
