Light aircraft systems are 14v or 28v. This product is rated at 12v and its big brother at 24v. Will the 12-14v and 24-26v discrepancies lead to aircraft systems damage?
No, the 12 volt version can be used on 14 volt systems without damaging the system. Same goes for 24 volt version on 28 volt aircraft systems.
