Description

The control unit AHD 502 is a microprocessor-controlled device for operation and indication of measuring point data of power of a bow thruster, consisting of a 3-phase-asynchronous motor (slip-ring rotor) with fixed propeller. As a standard, control units are installed in wheelhouse control console (master control unit) and in wing control stands (slave control units) of the ship.
