Victron Energy VDI-64 Galvanic Isolator
Protect Your Boat from Electrolytic Corrosion
The Victron VDI-64 Galvanic Isolator is a vital component for safeguarding your boat’s underwater metal parts—such as the hull, propeller, and shaft—from electrolytic corrosion caused by stray DC currents entering through shore power connections.
Key Features:
-
Prevents Electrolytic Corrosion
Blocks low-voltage DC currents that can lead to corrosion of underwater metal components. -
Dual Diode Anti-Parallel Design
Internally equipped with two diodes connected in anti-parallel. This configuration blocks DC current flow below ~1.4 VDC while allowing higher AC fault currents to pass safely. -
Automatic Fault Protection
In case of a higher-than-normal AC error voltage, the diodes conduct and allow the residual-current device (RCD) to trip—ensuring full system safety. -
Simple Inline Installation
Mounts directly behind your boat’s 230V shore power connection. No need for complex rewiring. -
Maintenance-Free Operation
Solid-state construction means no moving parts, no sparks, and no user interaction required.
Why Use a Galvanic Isolator?
Without protection, stray DC currents from shore power can create a galvanic reaction between different metals submerged in water. This leads to rapid corrosion, expensive repairs, and potential safety hazards. The VDI-64 isolates your boat from these currents while still allowing normal AC operation and fault protection.
Extend the life of your marine equipment and prevent costly damage with the trusted protection of the Victron Energy VDI-64 Galvanic Isolator—a must-have for any vessel connected to shore power.
