Buffer power supply - ensures continuity of operationThe buffer power supply unit is an electrical device that converts 230 V mains voltage to DC voltage. Its specificity lies in the fact that we can connect an external battery to it, from which energy will be drawn in case of a 230 V power outage, ensuring the continuity of the receiving device.More efficient cooling of the deviceThe perforated metal casing facilitates airflow, which results in more efficient cooling of the unit. 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 in a given range with a potentiometer.
