The buffer power supply is an electrical device that converts the 230V network voltage into DC voltage. It allows the connection of an external battery, from which energy will be drawn in the event of a 230V power outage, ensuring the continuity of the connected device's operation.

The perforated metal casing facilitates air flow, resulting in more efficient cooling of the device. The terminals are included accordingly and are used for connecting the wires according to electrical principles. The installer can adjust the output voltage within a specific range using a potentiometer.
