This model offers EXTRA Protection over standard Galvanic isolators.

The most obvious benefit is the Status Alert Indicator, which constantly monitors your boats earth connection for faults that could lead to corrosion of the hull, or even life threatening mains voltage earth leakage faults.

Bright, easy to read indicators warn you immediately a problem is detected.

Extra Protection. Under the bonnet, there is our "2-stage Protection System", which protects your hull against electrical noise and Galvanic & Stray Voltages up to twice as high as a normal Galvanic isolator.

Extra Protection is strongly advised - especially if you have electronic items on board.

Most electronic equipment, mobile phones, computers, TV's etc have "switch mode power supplies, and these can introduce electrical "Noise" into your boats electrical system. In extreme cases, the noise can defeat single stage galvanic isolators, so we have developed our Extra - Protection System to give you added protection.

How It Works...

Check your earthing at a glance.

Both Lights OFF: Your Galvanic isolator is operating normally. No action required, so just check back occasionally to ensure that all's well.

One Light ON: If either of the lights are on, it indicates DC leakage. This can cause severe corrosion to your boat. Our instructions give clear basic advice on how to resolve the problem.

BOTH lights ON: If both lights are ON, this indicates AC leakage, usually from the mains wiring or a connected appliance. AC leakage can be a danger to life. Please see instructions for help in rectifying the problem.
