Overview

The Garmin 010-13336-00 is a voltage converter unit for Garmin GMR xHD3 series open-array radars. On compatible 4 kW xHD3 versions, this module is used to achieve a 100-knot wind rating.

It is meant for radar installations where the converter is specified as part of the power setup. Once installed, the radar system can better match the wind-load requirements that come with open-array use on faster boats and in rougher conditions.

Key features

• Built for the Garmin GMR xHD3 series of open-array radars
• Used on compatible 4 kW xHD3 versions
• Supports a 100-knot wind rating when used with the compatible radar setup
• Converter-module format intended to be installed as part of the radar power arrangement

Compatibility and fit

This unit is specific to the GMR xHD3 open-array radar family. Confirm your radar model and power requirements before ordering, especially if you are working with a 4 kW xHD3 version where the 100-knot wind rating is part of the install plan.

Installation and setup

Plan for a mounting spot that is dry, protected from direct spray, and supported against vibration. Keep cable runs tidy with strain relief and a drip loop where appropriate, and avoid routing near sharp edges or high-heat areas. After installation, re-check fasteners and cable support after the first few trips, since new wiring and mounts can settle once the boat starts pounding again.

Electrical and system integration

This converter is part of the radar power chain, so clean power and good terminations matter. Follow the radar’s specified fuse protection and wiring practices, keep connections corrosion-free, and avoid tying the radar feed into circuits that see frequent voltage sag from large intermittent loads.

Use on board

This is a good match for owners running a GMR xHD3 open-array radar on a boat that sees higher speeds or heavy weather, where wind loading is a real consideration. Offshore fishing boats, sport cruisers, and performance center consoles are common use cases when the radar installation targets the 100-knot wind rating.
