The Raymarine ACU-300 is a specialized Actuator Control Unit designed for solenoid-controlled steering systems and Raymarine hydraulic linear drives. Operating as part of the Evolution autopilot series, it interfaces directly with solenoid drive units, constant running hydraulic pumps, and rudder reference units, routing command signals across the SeaTalkng / NMEA 2000 network to the EV-1 sensor core and control heads.
