STPRO 4004 180°
This controller ensures that the fins can rotate 180° in a secure way, this allows the ship to sail with a single set of stabilizers in both directions.

In order to turn the stabilizers 180°  in a safe manner, the STPRO4004 180 controls various data of the sailing direction, water depth, speed, etc. These data obtained by different sensors, will be double checked and processed by the STPRO4004 180°, the controller sends  the processed  data to one of the two STPRO4004 controllers.
