NAC-3 Autopilot Computer

SKU: 000-13250-001

Autopilot Comptuer

Product details

The NAC-3 Autopilot Computer is the brain behind your autopilot system. NAC-3 contains the control algorithms developed to drive a boat across a broad range of weather conditions and sea-states, alongside the electronics needed to operate a hydraulic or mechanical drive unit, while also interfacing with other components including heading sensors and rudder feedback units. The NAC-3 was designed for boats 33 feet or greater in length and is rated to operate high-current hydraulic drives, mechanical drive units, and solenoid valves with a current rating of 30 Amps continuous (50 Amps peak).

Key Features

  • Recommended for boats above 10 metres (35 feet) 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 RF25 rudder feedback units
  • NMEA 2000® connectivity to heading sensors, rudder feedbacks, dedicated autopilot controllers, and multifunction displays
  • NMEA 0183® input
