Description
The galvanic isolator prevents electrolytic corrosion. It blocks low voltage direct currents that enter your boat through the shore power ground wire. These currents can cause corrosion of submerged metals in the boat, such as the hull, propeller, shaft, etc.
The galvanic isolator consists of two diodes connected in antiparallel. When connected in this way, the diodes allow current to flow in both directions, but only above a certain voltage threshold. The voltage at which the diodes conduct is approximately 1.4 Vdc.
The isolator is installed directly behind your boat's 230V connection. The forward voltage of the galvanic isolator is greater than the potential difference between the metals. Therefore, this voltage does not allow conduction and the galvanic isolator therefore prevents any electrolytic current. However, if there is an error (higher) voltage in the AC circuit, the diodes will pass current and the RCD will interrupt the circuit.
Delivery
Oversized products such as solar panels or heavy products such as refrigerators are excluded from the free shipping policy for orders of $100 or more, as well as the $10 flat rate shipping for orders of $99.99 or less. If an item in your order is one of the restricted items, we will contact you to let you know.
