The NAC-3 Autopilot Computer is the brains behind your Simrad autopilot system.The NAC-3 Autopilot Computer is recommended for boats above 35' in length. It is rated for high-current output of up to 30A continuous and 50A 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. 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. Key Features Reliable autopilot performance based on Simrad Continuum steering technology Recommended for boats above 35' in length 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 multi-function displays with NMEA 0183 Simrad Continuum steering technology:Every Simrad steering innovation builds upon a legacy encompassing over sixty years of autopilot development, which continues today at Simrad Yachtings autopilot research hub in Norway. This legacy is exemplified by the Continuum algorithm: the software that drives Simrad steering technology. Continuum brings all those years of research and on-water experience to your helm, for a smart pilot you can trust to take the wheel. Virtual Rudder Feedback:Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to install a separate rudder feedback unit aboard outboard and sterndrive boats. This reduces overall autopilot system cost and complexity, and is ideal where a feedback unit is impractical due to mechanical constraints. 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 Simrad Continuum steering algorithm to make the best-informed steering decisions
