Autopilot Core Pack
This pack includes the Simrad NAC-3 autopilot computer, RF25N rudder feedback
unit, Precision-9 solid-state compass, plus all cabling and connectors required
to build an NMEA 2000 network backbone or connect your autopilot system to an
existing NMEA 2000 network. To create a complete Simrad Continuum autopilot
system, just add a hydraulic pump or mechanical drive unit to suit your steering
system, and choose a dedicated autopilot controller or Simrad multifunction
display.
NAC-3 Autopilot Computer
The NAC-3 Autopilot Computer is recommended for boats above 10 metres (35
feet) in length. It is rated for high-current output of up to 30 amps continuous
and 50 amps 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.
Multiple Control Options
Choose from a range of dedicated autopilot controllers, or control your
autopilot from your existing multifunction display or glass bridge with full
Simrad display integration. Install extra autopilot stations, ideal for
dual-helm vessels, or add the Simrad WR10 wireless remote for instant steering
and autopilot control from anywhere on board.
RF25N Rudder Feedback Unit
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 possible. These sensors are typically used
on boats with inboard engines, on larger vessels, and in special applications
where Virtual Rudder Feedback may not be suitable. The RF25N included in this
pack connects directly to your boats NMEA 2000 network, simplifying the
cabling required for installation.
Simrad Precision-9 Compass
The Precision-9 Compass supplies accurate heading and rate-of-turn
information to your autopilot and other onboard systems over an NMEA 2000 connection. Heading is determined by an internal array of solid-state sensors
that constantly measure motion and orientation on nine axes. The Precision-9's
solid state technology is not only accurate and precise, but also exremely
reliable with no internal moving parts. An easily adjustable mounting bracket
and single-cable connection allow simple installation aboard any vessel,
including up-mast mounting suitable for interference-free operation with steel
hulls.
Automatic Tuning and Calibration
Auto-tuning simplifies setup and ensures optimal steering performance.
Automatic compass calibration improves heading accuracy as you travel, using
data gathered by the Simrad Precision-9s internal array of solid-state sensors.
Easy Installation
Industry-standard NMEA 2000 networking and NMEA 0183 input allow simple
connectivity to sensors, autopilot controllers, and multifunction displays
located anywhere on board.
