Details

The NAC-3 Autopilot Computer is the brains behind your B&G 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 ten metres (35 feet) or greater in length and is rated to operate high-current pumps, mechanical drive units, and solenoid valves (30 amps continuous/50 amps peak).

B&G Reflex steering technology

Every B&G steering innovation builds upon a legacy encompassing over sixty years of autopilot development, which continues today at Navico's autopilot research hub in Norway. This legacy is exemplified by the Reflex algorithm: the software that drives B&G steering technology. Reflex brings all those years of research and on-water experience to your helm, for a smart pilot you can trust to take the wheel.

High-Current Output

The NAC-3 Autopilot Computer is recommended for boats above 10 metres (35 feet) in length. It is rated for high-current output of up to 30 amps continuous and 50 amps peak, plus a clutch output; this is suitable to operate high-current drive pumps including the Simrad RPU160 and RPU300, mechanical drives such as the Simrad DD15, hydraulic linear drives such as the HLD2000 series, and solenoid valves.

Rudder Feedback Units

Rudder feedback units are sensors that connect to your rudder via a mechanical linkage and continuously report actual rudder position to your autopilot computer allowing the B&G Reflex steering algorithm to make the best-informed steering decisions possible. The NAC-3 supports SimNet or NMEA 2000 connected RF25 feedback units, and rudder feedback sensors with variable frequency output including the RF300.

Easy Installation

Industry-standard NMEA 2000 networking and NMEA 0183 input allow simple connectivity to heading sensors, rudder feedback units, autopilot controllers, and multifunction displays located anywhere on board.
