30 Amp Prosafe Isolator FAIL SAFE Galvanic Isolators will interrupt Galvanic current flow with other boats at a marina when installed on a boat which is connected to AC Shore Power. This technology maintains AC safety ground and solves the most common forms of corrosion and premature zinc loss within a boats bonding system. The ProSafe FS Series is UL Certified to meet the parameters of the ABYC A-28 recommendation. ProSafe FS installs easily and does not require a dedicated monitor to verify the operational status of the Galvanic isolator as required by non-Fail-Safe Certified Galvanic isolators. Both the ProSafe 30 and 60 Amp models are built on robust Flat Pack Semiconductor platforms, ensuring that in the event of a failure, the failure is safe by not compromising the ground continuity on-board when connected to AC Shore Power.
