Řídicí jednotka autopilota NAC-3

The NAC-3 autopilot computer is designed for larger boats, typically over 10 metres (35 feet), which require high-current power units such as hydraulic pumps or powerful mechanical actuators.

The NAC-3 processor is compatible with 12V DC and 24V DC electrical systems. It can operate within a voltage range of 10 to 30 V DC.

The NAC-3 is very versatile in terms of connectivity. It has the following ports:

NMEA 2000 (via a Micro-C port) for modern integration. NMEA 0183 (bidirectional port) for compatibility with older equipment. SimNet compatibility to integrate with existing Navico systems.

The NAC-3 processor is designed to manage power units (pumps, actuators) with a maximum consumption of 750 W. It can supply high continuous current for demanding applications.

It is recommended to install a 30 Amp fuse on the power line of the NAC-3 computer to ensure adequate system protection.

The NAC-3 processor is part of the Navico ecosystem and is designed to integrate seamlessly with the multifunction displays from Simrad, Lowrance, and B&G brands.

The NAC-3 autopilot computer is designed to operate within a temperature range of -25°C to +55°C (-13°F to 131°F).

The NAC-3 is a more powerful version than the NAC-2. It is designed for larger vessels and can handle higher-power units (pumps and actuators) with a higher output current and a maximum consumption of 750 W.

During installation, ensure the NAC-3 computer is placed at least 500 mm (20 inches) away from any magnetic compass to avoid interference.

Yes, the NAC-3 integrates advanced autopilot algorithms for sailing, including an intelligent wind mode that automatically switches between apparent wind angle (AWA) and true wind angle (TWA) for optimal performance.

The NAC-3 autopilot computer weighs 0.7 kg (1.6 lbs).

SteadySteer is a technology that allows manual control of the helm without having to disable the autopilot. The autopilot automatically disengages when you turn the helm and re-engages when you hold it steady.

Yes, the NAC-3 includes pre-programmed turning patterns that can be activated from a compatible display. These patterns include maneuvers such as circles or zigzags, useful for certain fishing or search activities.

The typical electrical consumption of the NAC-3 depends entirely on the power unit (pump or cylinder) connected to it. The computer itself has very low power consumption, as the power is primarily drawn by the rudder actuator.

The NAC-3 has a Load Equivalency Number (LEN) of 1 on the NMEA 2000 network. This corresponds to the standard electrical load of a device on the network, useful information for designing your NMEA 2000 network.

The NMEA 0183 port of the NAC-3 is versatile and supports multiple communication speeds (baud rates): 4.8, 9.6, 19.2 and 38.4 kbaud, ensuring compatibility with a wide range of devices.

The NAC-3 autopilot computer comes with a 2-year manufacturer's warranty.

The NAC-3 processor is specifically designed for large vessels requiring high-power consumption units.

Maximum consumption: up to 750 W for hydraulic rams and pumps. Power supply: compatible with 12 V and 24 V DC systems. Protection: requires a recommended 30 A fuse.

The NAC-3 processor integrates seamlessly with Simrad, Lowrance, and B&G multifunction displays.

In terms of network connectivity, it supports:

NMEA 2000: via a standard Micro-C port.
NMEA 0183: bidirectional port for communication with older equipment.
SimNet: compatibility ensured for existing installations.

The computer housing has an IPX5 waterproof rating, effectively protecting it against water spray in a marine environment.

During installation, it is important to maintain a minimum safe distance of 500 mm (50 cm) from any magnetic compass to avoid interference.
