Eliminate the worries of hooking up to unknown shore power—this transformer isolates the boat's AC system from shore, protecting valuable electronics and electrical components from shore-side power surges, transients and spikes. This unit eliminates the need for polarity alarms and galvanic isolators since it stops galvanic current flow without electrical components. Fully encapsulated components and transformers eliminate vibration worries. Also features a thick sheet of copper between the primary (shore side) and secondary (boat side) windings of the transformer for added protection against strong shore-side voltage surges.
