The Victron Galvanic Isolator VDI-32 A is an essential component for protecting your boat’s electrical system from electrolytic corrosion caused by galvanic currents. It features two diodes connected in an anti-parallel configuration, allowing current flow only when the voltage exceeds approximately 1.4 Vdc. This ensures that safe, harmless currents pass through while blocking the damaging electrolytic currents that can cause serious corrosion to metal components in marine environments.
Installed directly behind your boat’s 230V AC connection, the isolator prevents electrolytic currents by maintaining a higher voltage threshold than the potential difference between metals. In the event of a higher error voltage in the AC circuit, the diodes safely allow the current through, causing the residual-current device to trip the circuit. With a robust IP67 protection rating, it’s built to withstand harsh marine conditions and is backed by a 5-year warranty for your peace of mind.
