Simrad NAC-3 High Current Autopilot Course Computer

Description

The Simrad NAC-3 High Current Autopilot Course Computer resolves heavy steering slippage and tracking fatigue by delivering industrial-strength drive actuation processing to large ocean cruising sailboats, heavy displacement yachts, commercial workboats, and passenger vessels. Operating on an adaptive 12 Volts DC or 24 Volts DC configuration layer, this high-current computing block pipes guidance telemetry straight into heavy-duty helm structures. Fleet captains can navigate shifting shipping channels or cross turbulent harbors safely, letting the computerized motherboard handle massive mechanical steering stresses smoothly.

Featuring an IPX5 jet-spray resistant case housing, the robust external shield isolates internal processing components from high-humidity bilge atmospheres and corrosive marine environments. The high-performance course computer delivers an impressive 30 Amps continuous output to drive high-capacity linear rams, hydraulic pumps, or solenoid valving without power faults. Integrating this standalone computing unit into your device bus network establishes precise rudder alignments, protected securely under a standard 2-Year limited warranty policy to eliminate unexpected mechanical maintenance downtime.
