Victron Galvanic Isolator VDI-64A - GDI000064000

Overview

The Victron Galvanic Isolator VDI Series (VDI-16, VDI-32, and VDI-64) is designed to prevent electrolytic corrosion in marine environments by blocking low-voltage DC currents that can enter a vessel through the shore power earth wire.

Installed directly behind the boat’s 230V shore power connection, the galvanic isolator safeguards underwater metal components while maintaining full electrical safety and compliance.

Key Features

Electrolytic Corrosion Protection

• Blocks galvanic DC currents from shore power earth
• Prevents corrosion of hulls, propellers, shafts, and fittings
• Essential for long-term marine vessel protection

Diode-Based Isolation Technology

• Internal anti-parallel diode configuration
• Allows current flow in both directions only above threshold voltage
• Diode conduction threshold of approximately 1.4 Vdc

Fail-Safe Electrical Safety

• Forward voltage exceeds normal metal potential differences
• Prevents electrolytic current flow under normal conditions
• Allows higher fault voltages to pass through
• Ensures residual-current device (RCD) disconnects the circuit safely

Marine Installation Ready

• Installed directly behind the 230V shore power inlet
• Designed specifically for marine AC electrical systems
