Newmar Galvanic Isolator with Failsafe

Sacrificial zincs corrode away as they protect metal thru hulls, shafts, and props from damaging electrolysis. Stray, low voltage current flowing between the AC safety ground and DC bonding system is a principal cause of this "galvanic" action.

Installing the Galvanic Isolator between the AC safety ground and DC bonding system blocks a majority of the low voltage currents and corrosive action on the zincs is significantly reduced (while the integrity of the critical safety ground path is maintained.) This means a significant saving in boat haul-out fees and zinc replacement costs. For additional safety, all units feature a large capacitor, providing a secondary low impedance path for sending AC current to the ground. Newmar's latest galvanic isolator meets the latest ABYC A-28 2019 including being failsafe.

This new design is able to meet the strictest temperature and current tests to create a robust solution for galvanic protection.
