NAC-3 High Current Course Computer
The NAC-3 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-3 was designed for boats 10M (33′) or greater in length and is rated to operate high-current pumps, mechanical drive units, and solenoid valves (30 Amps continuous/50 Amps peak).
Features:
- Reliable autopilot performance based on Simrad Continuum steering technology
- Recommended for boats above 10M (33′) in length
- High-current output of 30 Amps continuous, 50 Amps peak
- Clutch output (3 Amps maximum)
- Compatible with high-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 and RF300 rudder feedback units
- NMEA 2000® connectivity to heading sensors, rudder feedbacks, dedicated autopilot controllers, and multifunction displays
- NMEA 0183® input
