Common Concerns Answered
Why is this galvanic isolator more expensive than others?
The ProMariner ProSafe FAILSAFE 30amp Galvanic Isolator features a 'Fail Safe Certified' design, a critical safety innovation that guarantees continued ground continuity even in the unlikely event of isolator failure. This inherent safety mechanism eliminates the need for a separate monitoring system, providing superior protection and peace of mind.
What are the benefits of a 'Fail Safe Certified' galvanic isolator?
The 'Fail Safe Certified' designation means that your vessel's essential ground continuity is never compromised, even if the isolator itself malfunctions. This contrasts with non-fail-safe units, where a failure could leave your boat vulnerable to electrical issues while still appearing functional. It ensures uninterrupted safety grounding for your AC shore power system.
Are there any known issues with this product?
The primary consideration is the initial investment, which may be higher than non-fail-safe alternatives. However, this is offset by the advanced 'Fail Safe' technology and the elimination of the need for a separate monitoring system, offering a comprehensive and ultimately more valuable safety solution.
Frequently Asked Questions
What is a galvanic isolator and why do I need one?
A galvanic isolator prevents galvanic corrosion, a destructive process where dissimilar metals in contact underwater (like your propeller and shaft) create an electrical current that erodes metal. You need one to protect your vessel's underwater gear from premature failure and costly repairs when connected to AC shore power, which can create a path for stray DC current.
How does the ProMariner ProSafe FAILSAFE 30amp Galvanic Isolator work?
It works by blocking stray direct current (DC) electricity from flowing between your boat and the shore ground connection, which is the primary driver of galvanic corrosion. Simultaneously, it allows alternating current (AC) safety ground signals to pass through, maintaining proper electrical safety grounding.
What does 'Fail Safe Certified' mean for a galvanic isolator?
'Fail Safe Certified' signifies that the isolator is designed to maintain essential ground continuity even if the isolator itself ceases to function. This ensures your vessel remains safely grounded at all times, a critical safety feature that non-fail-safe units do not offer.
Is the ProMariner ProSafe FAILSAFE 30amp Galvanic Isolator ABYC compliant?
Yes, this galvanic isolator is ABYC A-28 July '08 compliant, meeting the established industry standards for marine galvanic isolators, ensuring it meets rigorous safety and performance requirements.
Can this galvanic isolator be mounted in an engine compartment?
Yes, this galvanic isolator is ignition protected according to ISO 8846 standards, making it suitable for safe mounting within an engine compartment where flammable vapors may be present.
