Equal to two conventional isolators in series.

   The Galvanic Isolator PLUS for Aluminum boats blocks electrolysis currents from flowing in the ground conductor of your shore power hookup. It provides approximately 2.5 volts of isolation to isolate electrolytic voltages from the dock but still pass safety currents to ground in the event of a short circuit, or power leakage on your boat.

Aluminum hulls have a built-in electric potential of -0.75 to -1.0 depending on the alloy, temperature, salinity and water movement. Conventional Galvanic Isolators provide only about -1.2 volts of negative isolation so protection is degraded by up to 80% to negative stray AC or DC voltages when used for Aluminum hulls.

The Yandina Galvanic Isolator PLUS for Aluminum boats provides approximately +/- 2.5 volts isolation in the ground lead of your shore power supply to isolate DC and AC electrolytic voltages coming from the dock.
