Protect your vessel’s underwater metals from costly damage with the Victron Galvanic Isolator VDI-16 A. This essential marine safety device effectively prevents electrolytic corrosion by blocking low-voltage DC currents that enter your boat through the shore power earth wire. These stray currents are a major cause of corrosion to components like your hull, propeller, and shaft. The VDI-16 A features an internal anti-parallel diode configuration, allowing current flow only above a 1.4 Vdc threshold. This deliberately higher forward voltage prevents the smaller potential difference between your boat’s metals from causing conduction and thus halts electrolytic current. For your safety, if a higher AC error voltage occurs, the diodes will conduct, allowing your residual-current device (RCD) to safely break the circuit. Rated for a maximum current of 16 A and housed in a fully waterproof (IP67) anodised aluminium enclosure, this isolator is a reliable, high-quality solution for marine power protection. Install it directly behind your boat's 230 V shore connection for immediate peace of mind.
