{"product_id":"navico-calculateur-pilote-automatique-nac-3","title":"NAC-3 Autopilot Computer","description":"\u003cp\u003eThe Navico \u003cstrong\u003eNAC-3\u003c\/strong\u003e autopilot computer is the brain of steering systems designed for larger vessels requiring high-power consumption units. It represents a significant upgrade over the NAC-2, capable of handling hydraulic rams and pumps with a maximum power draw of 750 W and high continuous current, protected by a recommended 30 A fuse.\u003c\/p\u003e\n\n\u003ch3\u003eSteering performance and algorithms\u003c\/h3\u003e\n\u003cp\u003eIntegrating Navico’s advanced steering algorithms, the NAC-3 is compatible with Simrad, Lowrance, and B\u0026G multifunction displays. It provides precise helm control and supports sophisticated navigation modes, including an intelligent wind mode that switches between apparent wind angle (AWA) and true wind angle (TWA) based on angle. Preprogrammed turning patterns (circle, zigzag) are also available. The computer is compatible with SteadySteer technology for assisted manual control.\u003c\/p\u003e\n\n\u003ch3\u003eConnectivity and system integration\u003c\/h3\u003e\n\u003cp\u003eThe NAC-3 is designed for seamless integration into both modern and legacy navigation networks. It features a \u003cstrong\u003eNMEA 2000\u003c\/strong\u003e port (Micro-C, 1 LEN) for easy communication with sensors and modern displays, as well as a bidirectional \u003cstrong\u003eNMEA 0183\u003c\/strong\u003e port (4.8 to 38.4 kbaud). Compatibility with the SimNet network is also ensured for older installations. It accepts a rudder angle sensor (rudder feedback) of variable voltage or resistive type (0-5 V) and includes an output for external alarms (100 mA max).\u003c\/p\u003e\n\n\u003ch3\u003eDesign and robustness\u003c\/h3\u003e\n\u003cp\u003eBuilt for the marine environment, the NAC-3’s housing has \u003cstrong\u003eIPX5\u003c\/strong\u003e waterproofing, protecting it from water spray. It is certified to EN60945 for shock and vibration resistance. Its operating temperature range is -25°C to +55°C, ensuring reliability in extreme conditions. The computer operates on 12 or 24 V DC and weighs 0.7 kg.","brand":"Navico","offers":[{"title":"Default Title","offer_id":53723743453524,"sku":"000-13250-001","price":1098.76,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/main_191f25f8-ccaf-4268-ae46-5a4db869bcc7.jpg?v=1772639219","url":"https:\/\/skysat.fr\/en-gb\/products\/navico-autopilot-computer-nac-3","provider":"Skysat","version":"1.0","type":"link"}
