The NAC-3 autopilot computer contains the electronics required to operate a hydraulic steering pump or mechanical drive unit, while also interfacing with rudder feedback units and NMEA 2000 devices.

Designed for vessels above 10 metres (33 feet) in length, the NAC-3 is rated to operate high-current drive pumps including the Simrad RPU160 and RPU300, mechanical drive units including the Simrad DD15, hydraulic linear drives such as the HLD2000 series and solenoid valves (30 amps continuous/50 amps peak).

The NA-3 can be controlled by various Simrad and B&G control units, such as dedicated autopilot controllers, Multifunction displays (MFDs) and autopilot remote controllers (used in combination with instrument systems, or any combination of the above).

PLEASE NOTE: A drive unit, heading sensor, NMEA 2000® network, and compatible autopilot controller or multifunction display are required to create a complete autopilot system. Some vessels may also require a rudder feedback unit.
