The NAC-3 is thecentre of your autopilot system, containing the electronics needed to operateand interface with other key components. The NAC-3 has been designed for boatsten metres (35 feet) or greater in length and is rated to operate high-currentpumps, mechanical drive units, and solenoid valves.
High-Current OutputThe NAC-3 Autopilot Computer is recommended for boats above 10 metres (35 feet)in length. It is rated to operate high-current drive pumps including the SimradRPU160 and RPU300, mechanical drives such as the Simrad DD15, hydraulic lineardrives such as the HLD2000 series, and solenoid valves.
Virtual Rudder Feedback
Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to installa separate rudder feedback unit aboard outboard and sterndrive(inboard/outboard) boats with planing hulls. This reduces overall autopilotsystem cost and complexity, and is ideal where a feedback unit is impracticaldue to mechanical constraints. For vessels that do require a physical rudderfeedback sensor, the NAC-3 supports SimNet or NMEA 2000® connected Simrad RF25feedback units, and rudder feedback sensors with variable frequency outputincluding the Simrad RF300.
Easy Installation
Industry-standard NMEA 2000® networking and NMEA 0183® input allow simpleconnectivity to heading sensors, rudder feedback units, autopilot controllers,and multifunction displays located anywhere on board.
