These heavy duty isolators allow charging multiple batteries automatically from one or two alternators, and prevent discharge or "dumping" of one battery into another. Each battery is charged according to its need without overcharging.
Rated for 12-48 volt negative ground DC systems. Feature conservatively rated diodes and a rustproof anodized aluminum heat sink case. Models are available for 70, 120 and 165 amp alternators.
Features:
Heavy duty construction
Rated for systems up to 48 volts DC
Rust-proof anodized aluminum case
Stainless steel mounting hardware provided
Protective covers provided for terminals
