Simrad NAC-2 Low Current Course Computer
Simrad NAC-2 Low Current Course Computer — Product description
Discover the power of effortless navigation with the Simrad NAC-2 Low Current Course Computer, the intelligent core that transforms your boating adventures on vessels up to 10 meters (33 feet). Engineered for precision, this autopilot computer leverages advanced Continuum steering technology to deliver smooth, reliable course-keeping even in choppy waters or shifting winds. Whether you're cruising coastal waters, exploring inland lakes, or tackling weekend fishing trips, the NAC-2 ensures you stay on track without constant helm adjustments, letting you focus on the journey and the views.
Why the NAC-2 Stands Out for Smaller Boats
For owners of outboards, sterndrives, or compact inboards, finding an autopilot that matches your boat's size and power needs can be tricky. The NAC-2 solves this by supporting low-current hydraulic pumps, mechanical drive units, and solenoid valves with up to 8 amps continuous (16 amps peak) output. Its virtual rudder feedback feature eliminates the hassle of traditional installations on outboard and I/O setups, making it a game-changer for DIY enthusiasts or those retrofitting older vessels.
- Superior Steering Control: Continuum algorithms adapt to sea conditions, minimizing rudder movement for fuel efficiency and extended gear life.
- Robust Build: Splashproof IPX5 rating handles spray and splashes, built to withstand the marine environment.
- Energy Efficient: Draws just 140mA plus drive load, ideal for battery-conscious setups on 12V or 24V systems.
- Clutch and Solenoid Ready: Dedicated outputs (3A clutch, solenoid up to 10A) for seamless integration with diverse steering systems.
Effortless Integration into Your Vessel's Network
Plug-and-play simplicity defines the NAC-2. Its Micro-C NMEA 2000 connector links effortlessly with Simrad heading sensors, RF25 rudder feedback units, multifunction displays, and dedicated controllers. No more wrestling with complex wiring—everything snaps together for a clean install. Pair it with variable voltage or resistive feedback (0-5V) for precise positioning, and you're ready to go. Boaters report setups taking under an hour, even without professional help.
Pro Tip: For outboard boats, enable virtual rudder feedback during commissioning to auto-calibrate without physical hardware, saving time and cost while maintaining pinpoint accuracy.
