    • The Yandina GI+ Galvanic Isolator PLUS for Aluminum Boats, blocks electrolysis currents from flowing in the ground conductor of your shore power hookup
    • It provides approximately 2.4 volts of isolation to isolate electrolytic voltages from the dock
      • Still passes safety currents to ground in the event of a short circuit, or power leakage on your boat
    • The Yandina Galvanic Isolator PLUS for Aluminum boats provides approximately +/- 2.5 volts isolation in the ground lead of your shore power supply
      • It isolates DC and AC electrolytic voltages coming from the dock
      • 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
      • Protection is degraded by up to 80% to negative stray AC or DC voltages when used for Aluminum hulls
    • Applications: Any shore power connection up to 50 amps
    • Only (1) required for dual 30 amp connections
    • No heat produced under normal use
    • Minimal temperature rise on maximum load
    • No heatsink mounting base required
    • Optional Capacitor available for AC leakage
    • Mounting and connection hardware included.
