“Smart” marine battery charging technology for 24 volt systems aboard, workboats, military vessels, commercial vessels, and recreational craft. These chargers interact with batteries providing the optimum three stage charge process for fast recovery and conditioning, maximizing performance and extending battery life.
A selector switch adjusts output voltage to adapt to gel-cell/flooded lead-acid/AGM battery types. An optional temperature compensation sensor also adjusts output for ideal voltage based on changes in the batteries’ ambient temperature. All models are housed in a rugged stainless steel case with a durable white powder coat finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.
