Furuno NavNet 3D Radar External Power Supply Unit

The Furuno NavNet 3D Radar External Power Supply Unit is a dedicated PSU-012 power module for specific Furuno DRS radar and NavNet 3D, TZtouch, or TZtouch2 multifunction-display installations. It is a radar-system power component that provides the required regulated supply for compatible radar scanners. It is not a radar scanner, chartplotter, display, GPS receiver, heading sensor, general-purpose DC converter, or standalone navigation device.

The PSU-012 is used with compatible Furuno DRS2D, DRS4D, DRS4A, DRS6A, DRS12A, and DRS25A radar scanners in specified NavNet system configurations. Exact power-supply requirements depend on the selected scanner, display, radar cable, and installation architecture. Confirm the exact Furuno radar model and system documentation before purchase, as some lower-power scanners may use direct DC input rather than an external PSU-012.

Radar Integration

The PSU-012 is part of a compatible Furuno NavNet radar system and does not carry radar video or control commands. The complete installation requires the appropriate Furuno radar scanner, radar cable, compatible NavNet display or processor, power source, and supporting GPS or heading data for radar overlay and tracking features where applicable.

Do not substitute the PSU-012 for another Furuno power module without consulting the radar installation manual. Radar is a navigation aid and does not replace a proper lookout, safe speed, official charts, local notices, or collision-regulation compliance.

Warranty and Saltwater Care

Furuno warranty coverage varies by region, distributor, proof of purchase, installation method, commissioning status, and intended use. Confirm applicable local warranty terms, exclusions, and authorized-service requirements before purchase.

The PSU-012 is intended for protected internal installation. Its enclosure should not be treated as salt-spray or corrosion proof. Keep the compartment dry, inspect terminals, cable glands, mounting hardware, and electrical connections regularly, and address any moisture, corrosion, overheating, or cable damage promptly. Follow Furuno grounding and maintenance guidance for the complete radar installation.

Before Ordering

Confirm exact compatible Furuno DRS scanner and NavNet 3D, TZtouch, or TZtouch2 display configuration, PSU-012 requirement, 12V or 24V supply, correct factory cable arrangement, protected mounting space, circuit protection, radar-network architecture, heading and GPS-source needs for supported functions, and qualified installation requirements before purchase.
