Analytic Systems IBI3-40-200 Ideal Battery Isolator 200A 40V 3-Bank

The Analytic Systems IBI3-40-200 is a 200-amp, 40-volt 3-bank ideal battery isolator designed for marine, RV, and automotive applications requiring multiple battery management. This advanced device allows all batteries to be fully charged from a single alternator while maintaining complete electrical isolation between battery banks or between a vehicle and trailer.

Key Features:

• Ideal Diode technology using MOSFET transistors reduces voltage drop to just 160 millivolts at 200 amps
• Essentially zero voltage drop at low current for maximum charging efficiency
• Waterproof epoxy-sealed construction for harsh marine and outdoor environments
• Simple installation with easy connection terminals
• Maximizes alternator output by minimizing power loss
• Ensures full battery recharge every time
• Three-year parts and labor warranty

Unlike traditional diode-based isolators that waste significant alternator power as heat, the IBI3-40-200 uses intelligent MOSFET control circuitry to apply virtually all alternator power directly to the batteries. This technology also allows the isolator to function as a converter for single-bank battery chargers, transforming them into multi-bank charging systems, or as a pure isolation diode between vehicle and trailer electrical systems.
