Simrad NAC-3 Autopilot RF25N Feedback Core Pack

Description

Use physical rudder-position feedback with the Simrad NAC-3 RF25N Feedback Core Pack, which includes a NAC-3 course computer, Precision-9 nine-axis AHRS, RF25N rudder-feedback sensor, and NMEA 2000 starter kit. The pack supports sailboats, heavy-displacement yachts, and commercial workboats with compatible inboard rudder hydraulic lines, mechanical tiller rams, or solenoid-valve steering. Its physical feedback sensor supports installations requiring measured rudder-position tracking.

The NAC-3 works with hydraulic cylinders from 250 cc to 500 cc, or 15.2 to 30.5 cubic inches. It provides 30A continuous output and up to 50A peak output for compatible linear drives, hydraulic pumps, or solenoids. Power support includes 12V and 24V DC systems, while maximum intermittent draw reaches 40A. The core unit carries an IPX5 rating and the RF25N sensor has an IPX7 rating.

Key Specifications of the Simrad NAC-3 RF25N Feedback Core Pack

• The core pack includes a NAC-3 course computer, Precision-9 nine-axis AHRS, RF25N feedback sensor, and NMEA 2000 starter kit.
• Sailboats, heavy-displacement yachts, and workboats can use compatible tiller, hydraulic, or solenoid-valve steering systems with this pack.
• The RF25N sensor provides physical rudder-position feedback for installations requiring measured steering-geometry synchronization during system commissioning.
• Hydraulic-cylinder capacity ranges from 250 cc to 500 cc, requiring exact cylinder-volume verification before drive selection.
• The NAC-3 provides 30A continuous drive output and up to 50A peak capacity for compatible pumps, linear drives, or solenoids.
• Operating voltage supports 12V or 24V DC systems, while maximum intermittent current draw can reach 40A under load.
• The NAC-3 has IPX5 protection and the RF25N carries IPX7 protection for the documented component environmental ratings.

System Integration and Feedback

This Simrad core pack does not include the separate steering drive or helm display needed for a complete autopilot installation. The NAC-3 course computer manages the selected drive, the Precision-9 supplies heading and attitude data, and the RF25N provides physical rudder-position feedback. Each component must be matched with the vessel’s steering configuration, electrical system, and NMEA 2000 backbone.

Physical rudder-geometry synchronization is part of the stated dockside setup process. Continuum Steering Technology, specialized wind tracking, and thruster-control integration are system functions that depend on the connected drive, heading source, display, vessel steering geometry, and complete commissioning procedure.

Why Choose the Simrad NAC-3 RF25N Feedback Core Pack

The Simrad NAC-3 RF25N Feedback Core Pack combines a NAC-3 course computer, Precision-9 nine-axis AHRS, RF25N rudder sensor, and NMEA 2000 starter kit. Its 250 cc to 500 cc cylinder range, 30A continuous output, 50A peak output, 12V or 24V support, IPX5 and IPX7 component ratings, and physical rudder-feedback configuration provide specific checks for higher-current autopilot system planning.

Setup and Network Considerations

Confirm that the vessel requires physical rudder-position feedback and has a compatible hydraulic, mechanical tiller, or solenoid-valve steering system before selecting this core pack. Verify the steering cylinder volume, choose a matching drive and display, and plan NAC-3, Precision-9, and RF25N mounting locations. Check NMEA 2000 connections, 12V or 24V supply, circuit capacity for up to 40A intermittent draw, and steering geometry before dockside setup.

Warranty and Support

Simrad warranty terms vary by product and region, and the supplied specifications do not provide a named warranty period for this core pack. Mulmarine.com can help you review RF25N feedback requirements, cylinder-volume range, drive selection, NAC-3 output capacity, sensor placement, NMEA 2000 network needs, power capacity, and separate helm-display requirements before purchase. Review the applicable Simrad warranty coverage and documented package contents before ordering.

Before Ordering the Simrad NAC-3 RF25N Feedback Core Pack

Confirm that your vessel requires an RF25N physical rudder-feedback sensor and uses a compatible hydraulic, mechanical tiller, or solenoid-valve steering configuration. You should verify a 250 cc to 500 cc cylinder range where applicable, selected steering drive, NAC-3 and RF25N mounting space, Precision-9 placement, NMEA 2000 capacity, 12V or 24V supply, 30A continuous and 50A peak drive requirements, and circuit capacity for 40A intermittent draw before purchase.
