More Information

Vessels with non conductive hulls, GRP, Wood, composites etc., need special protection for their metallic parts that are in the water.

That's because 
on GRP and similar craft, the underwater metallic parts, (outboards, sterndrives, cooling inlets etc.),  are typically made from "SOFT" metals such as Aluminium, Brass etc, which corrode VERY easily. That's why it's essential to choose a Galvanic Isolator with the lowest leakage possible. This model is designed with specially selected components to give the very best protection for GRP hulled boats.

AC Bypass Capacitors
how to contact galvanic isolator company
AC Bypass Capacitors - Why you need one
A Galvanic Isolator works by blocking "Corrosion Currents". It's simple and cost effective, and thousands are sold every year.
Unfortunately, some manufacturers try to cut costs by failing to fit an AC Bypass Capacitor. It's definitely a false economy. 
Galvanic Isolators are designed to block Galvanic Currents, (which are Direct Current), whilst allowing Alternating Current to pass. Unless a Capacitor is fitted, those Alternating Currents can defeat the Galvanic Isolator and make it ineffective. An AC Bypass Capacitor directs the Alternating Current around the isolator's internal components, so that it can work effectively in all situations.
Without an AC Bypass capacitor, an isolator may work very poorly, if at all. The value (or size) of the Capacitor must be carefully chosen. If it's too low a value, it won't be effective, and if it's too high a value, it may be physically to large to be practical.
