The buffer power supply is an electrical device that converts 230V voltage to DC. It has the peculiarity that we can connect an external battery to it, from which energy will be drawn in case of a 230V power outage, in order to ensure the continuity of the device's operation.

The perforated metal case facilitates airflow, resulting in more efficient cooling of the device. The terminals are appropriately labeled and are used for connecting the wires according to electrical standards. The installer can adjust the output voltage within a specific range using a potentiometer.
