Garmin GMR™ Voltage Converter Unit f/xHD3 Radars

The Garmin GMR Voltage Converter Unit for xHD3 Radars is a specialized power conditioning module designed to expand the operational capability of Garmin's 4 kW xHD3 open-array radar systems. This optional equipment enables compatible 4 kW xHD3 radars to achieve an enhanced 100-knot wind rating, making it an essential upgrade for marine operators who require extended environmental performance specifications beyond standard configurations.

The converter module handles the voltage regulation and power delivery optimization required to support the xHD3 radar's full operational envelope in higher wind conditions. By conditioning the electrical input to the radar unit, this converter allows mariners to maintain consistent radar performance during severe weather events and challenging sea states where wind speeds approach or exceed typical operational thresholds. The compact module measures 9 × 4 × 13 inches and weighs 3.3 pounds, making it straightforward to integrate into existing radar installations without significant spatial constraints.

This upgrade is particularly valuable for commercial fishing vessels, offshore patrol operators, and serious recreational cruisers whose vessels operate in coastal or deep-water environments where wind conditions frequently exceed standard radar operating parameters. The GMR xHD3 series is recognized for its solid-state technology and digital signal processing, and this voltage converter directly enables that hardware to perform at its design limits. Original Garmin part number 010-13336-00, this converter ensures authentic compatibility and maintains warranty integrity across GMR xHD3 4 kW radar installations.
