The Victron Galvanic Isolator VDI-16A is a compact, marine-grade device that protects underwater metalwork from electrolytic corrosion by blocking DC currents on shore power. It’s designed for boats with standard 120V–230V shore power connections and built for durability in harsh marine conditions.
-
Maximum current rating: 16 A max rating for typical boat shore power connections.
-
Waterproof, potted construction: Engineered for marine durability with a robust waterproof seal.
-
DC galvanic isolation with anti-parallel diodes: Internal two anti-parallel diodes conduct only above ~1.4 V DC, preserving normal operation while preventing harmful currents.
-
Installation position: Installed directly behind the boat’s 120V–230V connection for optimal protection.
-
Marine-grade design: Specifically designed to withstand the tough conditions of marine environments.
-
Shore power compatibility: Seamless compatibility with standard marine shore power setups.
