Newmar Battery Isolator

This heavy-duty isolator allows charging multiple batteries automatically from one or two alternators and prevents the discharge or 'dumping" of one battery into another. Each battery is charged according to its need without overcharging and is rated for 12-, 24-, or 36V negative ground DC systems.

Features:

• Conservatively rated diodes and a rustproof anodized aluminum heat sink case
• Heavy-duty construction
• Rated for systems up to 48V DC, negative ground
• Rust-proof anodized aluminum case
• Stainless steel mounting hardware is provided
• Protective covers are provided for terminals
