NAC-2 Low Current Course Computer
The NAC-2 Autopilot Computer is the brains behind your Simrad autopilot system. It contains the electronics needed to operate a hydraulic steering pump or mechanical drive unit, while also interfacing with other components including heading sensors and rudder feedback units. The NAC-2 was designed for boats up to 10M (33′) in length and is suitable for low-current pumps, mechanical drive units, or solenoid valves (8 Amps continuous/16 Amps peak).
Features:
- Reliable autopilot performance based on Simrad Continuum steering technology
- Recommended for boats up to 10M (33′) in length
- Output of 8 Amps continuous, 16 Amps peak
- Clutch output (3 Amps maximum)
- Compatible with low-current drive pumps, mechanical drives, hydraulic linear drives, and solenoid valves
- Virtual rudder feedback for simplified installation aboard outboard and sterndrive (inboard/outboard) boats
- Supports Simrad RF25 rudder feedback units
- Plug-and-play connectors for easy installation
- NMEA 2000® connectivity to heading sensors, rudder feedbacks, dedicated autopilot controllers, and multifunction displays
