Raymarine ACU 400 Evolution Modules

Raymarine ACU-400 Evolution Autopilot Actuator Control Unit

Experience unparalleled autopilot performance and unwavering command on the water with the Raymarine ACU-400 Evolution Actuator Control Unit. As the powerful core of the award-winning Evolution autopilot system, the ACU-400 is engineered to provide robust, reliable power and precise control for larger vessels with higher-capacity steering systems. Designed for the most demanding marine environments, this essential component translates the intelligent commands from the EV-1 sensor core into powerful, decisive action at the rudder, ensuring your vessel stays true to its course in any sea state.

The ACU-400 is one of the key modules in the Evolution ecosystem, serving as the muscular link between the system´s brain and the vessel´s steering mechanism. It delivers ample, consistent power to a wide range of Raymarine hydraulic, mechanical linear, and rotary drive units. This makes it the ideal choice for larger sailboats and motor yachts that require significant force to manage their steering systems effectively. Its rugged construction ensures long-lasting durability, giving you the confidence to navigate coastal waters or embark on long-distance offshore passages. The intelligent design of the ACU-400 integrates seamlessly into your boat´s network, providing a stable and highly responsive autopilot experience that feels like a seasoned helmsman is at the wheel.
