Overview

The Raymarine E52091 is a VCM100 voltage converter module for Raymarine HD and Magnum open array radar pedestals. It takes 12 V or 24 V DC from the boat's electrical system and feeds the radar through the converter module, which is the required power path for these scanners.

This is the dedicated converter used between vessel power and the radar pedestal, not a general-purpose power supply for mixed onboard electronics. In a single-scanner installation, each radar requires its own VCM100.

For buyers replacing an existing unit, the key fit point is straightforward: this module belongs in Raymarine open array radar systems that call for the VCM100 in the power circuit. It is intended for below-decks installation, close to the DC source, where cable runs can be kept short and well supported.

Key features

• Replacement VCM100 converter module for Raymarine HD and Magnum open array radar systems
• Works with 12 V and 24 V DC vessel power systems
• Radar scanner power is routed through the VCM100 rather than direct from the battery
• One converter module is used per radar scanner
• Splashproof housing for below-decks mounting
• Vertical mounting position helps with heat dissipation and cable management
• Includes dedicated POWER IN, POWER OUT, and SCREEN connections for proper integration with the radar power circuit and vessel RF ground

Installation and setup

The module should be mounted vertically on a solid surface in a ventilated below-decks space. Keeping it near the battery isolator switch or DC distribution panel helps reduce voltage drop and keeps the installation cleaner.

Power should be brought into the VCM100 from the vessel supply with suitable circuit protection, and the SCREEN terminal should be connected to the vessel's RF ground system. It should also be kept at least 1 m from a magnetic compass and away from equipment that can introduce electrical interference.

Compatibility and fit

This module fits Raymarine HD and Magnum open array radar installations that use the VCM100 between the scanner and the boat's DC supply. It is a practical replacement when an existing converter has failed, or when a radar installation is being completed with the matching power component the scanner requires.

It suits boaters running an open array radar on cruising boats, sportfishing boats, and other vessels where the radar pedestal is powered from a 12 V or 24 V DC system through a dedicated converter module.
