Victron Energy Galvanic Isolator VDI-16

Victron Galvanic Isolator VDI-16, VDI-32, and VDI-64 – Prevent Electrolytic Corrosion and Protect Your Boat

The Victron Galvanic Isolator is a vital component for preventing electrolytic corrosion in marine environments. Designed to block low-voltage DC currents that enter your boat via the shore power earth wire, it protects underwater metals such as the hull, propeller, and shaft. By installing the galvanic isolator directly behind your boat’s 230V connection, you ensure maximum protection for your vessel’s vital components.

Key Features of the Victron Galvanic Isolator

Prevents Electrolytic Corrosion

Electrolytic corrosion occurs when low-voltage DC currents flow through the shore power earth wire, causing damage to submerged metal parts of the boat. The galvanic isolator blocks these currents, safeguarding the integrity of critical underwater components.

Advanced Diode Technology

The galvanic isolator uses two diodes connected in an anti-parallel configuration. This design allows current flow in both directions but only above a threshold voltage of approximately 1.4V DC, effectively preventing the passage of galvanic currents.

Failsafe Protection

In the event of a higher error voltage in the AC circuit, the diodes allow current to flow, ensuring the residual-current device (RCD) trips to break the circuit. This dual functionality provides an added layer of safety for your onboard electrical system.

Easy Installation

The galvanic isolator is installed directly behind the boat’s 230V shore power connection. Its compact and robust design makes it easy to integrate into your existing electrical setup while ensuring reliable, long-term performance.
