Description

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 protects underwater metal components while maintaining full electrical safety and compliance.

Key Features

Electrolytic Corrosion Prevention

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

  • Forward voltage exceeds potential differences between metals
  • Prevents normal electrolytic current flow
  • Allows higher fault voltages to pass through
  • Ensures residual-current device (RCD) can disconnect the circuit safely

Marine Installation Ready

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