Description
Raymarine ACU-200 | High-Current Drive Control & SeaTalkng Integration
Optimize your vessel steering response using the Raymarine ACU-200, an actuator control unit engineered to provide reliable power to Type 1 hydraulic, linear, and rotary mechanical drives. This robust interface translates pilot commands into precise mechanical movement, ensuring consistent torque delivery and responsive handling even when navigating through challenging coastal currents or heavy following seas.
Designed for seamless integration within Evolution autopilot systems, this unit connects directly to the SeaTalkng backbone for high-speed data communication. Proper ventilation of the ACU-200 housing is essential to manage thermal loads during continuous operation, preventing internal circuit throttling and ensuring long-term reliability of the drive electronics.
Technical Key Features
- Supports Type 1 mechanical drive units.
- SeaTalkng interface ensures rapid data transit.
- Delivers 15A continuous current output capacity.
- Dual 12V and 24V system compatibility.
- IPX2 rated for protected internal mounting.
- Built-in reference sensor for rudder feedback.
- Compatible with Evolution EV-1 sensor cores.

Raymarine ACU-200 Actuator Control Unit Technical Guide
The ACU-200 is a versatile power interface designed to drive Raymarine Type 1 hydraulic pumps, as well as Type 1 linear and rotary mechanical drives. It acts as the command center that translates electronic signals from the EV-1 sensor into physical movement for vessels with mid-range steering loads.
Yes, the ACU-200 is dual-voltage compatible, operating on both 12V and 24V DC. However, you must ensure that the drive unit (pump or motor) connected to it matches the vessel's voltage bank to prevent electrical damage or insufficient steering torque.
One of the primary advantages of the ACU-200 is its ability to supply backbone power to the SeaTalkng network. This eliminates the need for a separate power cable for your EV-1 sensor and p70 series control heads, simplifying the overall wiring architecture.
The unit provides a continuous 15A output, which is the industry standard for Type 1 actuators. It also features a dedicated clutch connection for mechanical drives, ensuring the autopilot can safely disengage for manual steering at the touch of a button.
While the Evolution system supports virtual rudder feedback, the ACU-200 includes a dedicated terminal block for a physical rudder reference. Using a physical sensor is highly recommended for inboard yachts to achieve the most stable and precise course keeping in rough seas.
