The buffer power supply is an electrical device that converts 230V mains voltage into DC voltage. Its specificity is that we can connect an external battery to it, from which energy will be drawn in case of a 230V power outage, so as to ensure the continuity of the receiving device.
The perforated metal casing facilitates the airflow, which results in more efficient cooling of the device. The screw terminals are marked accordingly and are used to connect the cable entries in accordance with electrical principles. The installer can adjust the output voltage within a certain range using a potentiometer.
