Need a Galvanic Isolator?

Galvanic Isolator - If you are experiencing quick disintegration of the Zincs mounted your boats underwater propulsion system chances are it is being exposed to stray leakage current from the shore power. This electrical phenomenon is usually result of leakage electrical current from the docks or another vessel tied up nearby. In certain circumstances these currents can get excessive causing dangerous waters for nearby swimmers as well as massive damage to the boats drive systems.

It is very difficult to find out who the culprit is that’s causing the problem and it could come back again even if resolved with a new boat shows up to the docks. The simplest and easiest solution to reducing the need to replace your sinks is to install a galvanic isolator is to eliminate the problem on your end. Adding a galvanic isolator is a low cost and simple to install device which will bring a quick conclusion to the problem. Please find below some of the products we offer to help resolve this problem.

Victron Energy Item #: GIV13020 -

The Victron Energy 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 boat’s 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...
