Unlock Precise Steering Control with the Raymarine ACU-200

Imagine gliding through choppy waters or navigating long passages without constantly adjusting the helm. The Raymarine ACU-200 Actuator Control Unit makes this a reality for small to mid-sized vessels equipped with mechanical or hydraulic steering systems. As the powerhouse behind Evolution autopilot setups, it seamlessly interfaces with Type 1 hydraulic pumps, linear drives, and rotary mechanical drives, ensuring responsive and reliable performance where it matters most—on the open sea.

What sets the ACU-200 apart is its robust engineering, tailored for real-world boating demands. It not only supplies steady drive power to your autopilot but also energizes the SeaTalk^ng network, keeping all connected devices humming efficiently. Boaters trust it for its ability to handle the rigors of saltwater exposure, sudden weather shifts, and extended voyages, delivering autopilot precision that feels almost intuitive.

Standout Features That Drive Performance

• Powerful Drive Output: Rated for a maximum continuous 15 amps at supply voltage, it provides the muscle needed for smooth, accurate steering corrections even in demanding conditions.
• Versatile Clutch Control: Supports up to 2 amps continuous output, configurable for 12V or 24V systems, giving you flexibility across different vessel setups.
• Network Powerhouse: Supplies up to 3 amps at 12V to the SeaTalk^ng bus (fuse-protected), ensuring your EV-1 sensor core, control heads, and instruments stay powered without additional wiring hassles.
• Harsh Environment Ready: From freezing decks to sweltering tropics, it operates flawlessly from -20°C to +55°C (-4°F to +131°F), with drip-resistant protection to shrug off spray and condensation.
• Effortless Integration: Plug-and-play connections for rudder reference (includes M81105 rotary unit), sleep switch, power, drive motor, clutch, and ground—simplifying installation on boats with hydraulic or mechanical steering.

These features translate to tangible benefits: less fatigue on long watches, pinpoint course-holding, and peace of mind knowing your autopilot won't falter when you need it most.

Detailed Technical Specifications

Built for compatibility and efficiency, the ACU-200 fits perfectly into 12V or 24V DC systems with an operating range of 10.8V to 31.2V. Standby power draw is minimal at 300mA from the main supply and just 20mA from SeaTalk^ng, preserving battery life during anchored nights or offshore adventures.

Compact yet capable, its footprint allows easy mounting in tight console spaces, while conformance to European EMC standards (2004/108/EC) and C-Tick ensures global reliability.

Perfect Fit for Your Vessel's Needs

For boats under 10 meters (33 feet) with Type 1 drives, the ACU-200 strikes the ideal balance between power and efficiency. Pair it with an Evolution EV-1 sensor core for advanced nine-axis heading and attitude sensing, and you've got an autopilot system that adapts to waves, wind, and heel like no other. Skip the guesswork—its SeaTalk^ng backbone enables seamless integration with multifunction displays, instruments, and even third-party NMEA 2000 gear via adapters.

Skip lighter-duty units like the ACU-100 (7A output, core-only power) and reserve heavier options like the ACU-400 (30A) for larger hulls. The ACU-200? It's the sweet spot for most recreational sailors chasing worry-free autonomy.
