Galvanic Isolators
Our Galvanic Isolators reduce the galvanic corrosion that results from stray power on the AC ground wire, protecting your boat and reducing maintenance costs. They are the only devices permitted to interrupt a boat's AC ground.
Battery Isolators
Designed for DC power systems, our Battery Isolators split power from charging sources, such as alternators and solar chargers. This ensures one battery cannot discharge into another and enables users to charge multiple batteries from a single alternator.
Galvanic Isolators
ProSafe™ FailSafe Galvanic Isolators
The ProSafe FailSafe series of galvanic isolators prevents the most common forms of corrosion and premature zinc loss. When installed on a boat connected to AC shore power, ProSafe FailSafe isolators interrupt galvanic current flow with other boats at a marina.
ProSafe FailSafe models are compatible with 30 and 50 amp shore cord applications.
