Dairyland (Formarly DEI) Galvanic Isolators (GI) are fail-safe, solid-state DC isolation/AC coupling devices with ratings and characteristics that significantly exceed those of all known galvanic isolators designed for marine applications. The proven fail-safe construction assures that the galvanic isolator never compromises the integrity of the grounding conductor, even in the unlikely case of the product failing.

The 30A Galvanic Isolator is appropriately rated for all 15A through 35A shore power services and has been fully tested to meet the July 2008 publication of ABYC A28, the standard governing galvanic isolators in the US marine industry. The DEI 30A Galvanic Isolator comes in both Fail-Safe Plus® and Fail-Safe MAX® versions, giving the customer increased options for safety. For international use, the 30A device has been rated to 35A to cover applications using 32A shore power connections.
