Pro Mariner 12073 Battery Isolator 2 Alternator 3 Battery 70 Amp

The Pro Mariner 12073 is a high-performance battery isolator designed to manage charging for multiple battery banks from dual alternator sources. This robust 70-amp unit allows two alternators to charge three separate battery banks simultaneously while preventing batteries from discharging into one another when the engine is off.

Key Features:

• Dual alternator input capability for maximum charging flexibility
• Three battery bank outputs for independent charging of separate systems
• 70-amp continuous duty rating for reliable high-current performance
• Gold-plated terminals for superior conductivity and corrosion resistance
• Improved efficiency design minimizes voltage drop during charging
• Solid-state construction with no moving parts for long-term reliability

Ideal for marine vessels, RVs, and commercial vehicles with complex electrical systems requiring simultaneous charging of house, engine start, and auxiliary battery banks. The isolator ensures each battery bank receives optimal charging while maintaining complete electrical isolation between banks.
