When correctly installed, the Galvanic Isolator blocks galvanic currents in the shore earth connection of up to 1.1V. Once the voltage exceeds this level, current is allowed to pass through, maintaining a safe earth connection.
For almost every combination of metals found at a typical mooring, the 1.1V threshold is sufficient to block corrosive currents. However, when the voltage at the earth connection rises above 1.1V, current can flow through the Galvanic Isolator, potentially leading to corrosion of submerged metals on the boat. In this situation, the shore power should be disconnected to help prevent hull corrosion.
D.C. galvanic currents can also be caused by other shore earth connections, such as telephone or cable TV systems.
The galvanic isolator is designed, manufactured, and tested to meet the ABYC A-28 standard and complies with the requirements of the British Marine Industry Federation. It is CE marked, fully encapsulated, and includes built-in RF suppression.
An analogue indicator clearly displays any DC current flowing, using an easy-to-read scale. Suitable for use with 120/240V 50/60Hz systems.
