Extralink AD-55B buffer power supply

A buffer power pack is an electrical device that converts 230V mains voltage into DC voltage. Its special feature is that we can connect an external battery to it, from which energy can be drawn in the event of a 230V mains voltage failure in order to ensure continuity of operation of the consumer device.

The perforated metal housing facilitates airflow, resulting in more efficient cooling of the unit. The screw terminals are marked accordingly and serve to connect the cable leads according to electrical principles. The installer can adjust the output voltage within a certain range using a potentiometer.
