Littelfuse Smart Battery Isolator, 12V, 200A Continuous, 750A Inrush, Black Plated Steel
Product Overview
Littelfuse Smart Battery Isolator offers an efficient automotive battery management solution that is smaller, lighter, and more flexible than traditional isolators. Compatible with all alternator types, it generates less heat and eliminates diode efficiency losses. The isolator reduces charging system workload by connecting the auxiliary battery only after the primary battery reaches 13.2 V, extending the life of charging components. It supports bi-directional charging from alternators or shore power chargers and features an LED status indicator for easy monitoring.Smart Battery Isolator, Plated Steel, Black, 200 A, 750 A Current Inrush, Input Terminals: 18 AWG, IP Rating: IP67/IP66, Mounting Hole Size: 5/16 x 19/32 in on 2-13/64 in, -40 to 85 °C, Output Terminals: 5/16-24, 12 V, For Boats, Heavy Trucks, RVs/Campers
