Note: These battery isolators are not compatible with self exciting alternators. Please consult the manufacturer of your alternator if you are unsure of your configuration.
The Newmar 2-3-70A Isolator is a heavy-duty voltage converter designed for managing multiple battery banks within 12-48 volt negative ground DC systems. This unit facilitates automatic charging of up to three batteries from one or two alternators, preventing current discharge between battery banks. It ensures each battery receives appropriate charge without overcharging, which is critical for maintaining battery health and system reliability in demanding applications. Constructed with a rustproof anodized aluminum heat sink case and conservatively rated diodes, it offers continuous operation up to 50�C. The isolator is suitable for environments requiring robust power management, such as commercial vehicles, marine vessels, or remote power installations. It addresses the challenge of efficiently charging multiple batteries while isolating them to prevent mutual discharge, ensuring critical systems remain powered. The part number for this specific model is 495-2370-1, rated for 70 amp alternators.
