Buffer power supply - ensures continuity of operation.

The AD-55B buffer power supply is an electrical device that converts the mains voltage of 230 V to DC voltage. It has the capability to connect an external battery, from which energy is drawn in the event of a failure of the 230 V voltage.

The perforated metal casing facilitates airflow for more effective cooling of the device. The screw terminals are appropriately marked and are used for connecting the output wires in accordance with electrical regulations.

The installation technician can adjust the output voltage within a specified range using a potentiometer.
