Product Details

Galvanic Isolator VDI-16, VDI-32 and VDI-64
The galvanic isolator prevents electrolytic corrosion. It blocks low voltage DC currents that enter your boat via the shore power earth wire. These currents can cause corrosion to the boats underwater metals, like the hull, propeller, shaft and so on.
The galvanic isolator consists internally of two diodes which are connected in anti-parallel fashion. When they are connected in this way, the diodes allow current in both directions but only above a certain threshold voltage. The voltage at which diodes conduct is about 1.4 Vdc.

The isolator is installed directly behind your boat's 230V connection. The forward voltage from the galvanic isolator is higher than the potential difference between metals. As a result, this voltage will not allow conduction and as such, the galvanic isolator will prevent any electrolytic current. However, if there is a (higher) error voltage in the AC circuit, the diodes will allow current through and the residual-current device will break the circuit.

Installation & Ventilation

  • Mounting Orientation: Must be mounted with its length vertical to ensure maximum cooling through natural convection.
  • Clearance: Maintain a minimum clear space of 10 cm around the product for proper ventilation.
  • Safety Warning: The product must be installed in a heat-resistant environment. Avoid placing chemicals, synthetic components, curtains, or other textiles in the immediate vicinity.
  • Operating Temperature: Under normal conditions, the temperature increase of the heat sink does not exceed 20°C; however, the unit may become hot when conducting a fault ground current.

Safety & Wiring Requirements

  • Correct Wiring: The galvanic isolator must be wired into the green (safety) grounding connection ahead of all other grounding connections to the vessel. This ensures that no ground connections on the vessel can bypass the isolator, which would render it ineffective.
  • Compliance: All connections and safety features must be implemented according to locally applicable regulations.
  • Cabling: Ensure the use of electric cables of the appropriate size for the 32A rating.
