Victron Argodiode Battery Isolator 140-3AC

Introducing the Victron Argodiode Battery Isolator 140-3AC, a cutting-edge solution for managing your vehicle's battery system. This isolator is designed to facilitate simultaneous charging of two or more batteries from a single alternator without the need for direct battery connections. With its advanced features, it ensures that discharging an accessory battery won't inadvertently drain your starter battery. The use of high-efficiency Schottky diodes minimizes voltage drop, enhancing the overall efficiency of your charging system.

Technical Specifications and Features

The Argodiode Battery Isolator 140-3AC is equipped with a low voltage drop, which is crucial for maintaining optimal battery health. At low current, the voltage drop is approximately 0.3 V, and at the rated output, it is approximately 0.45 V. This isolator also comes with a compensation diode that can be utilized to slightly increase the output voltage of the alternator, effectively compensating for voltage drop across the diodes. This feature ensures that your batteries receive the most efficient charging possible, reducing wear and tear and extending their lifespan.

Practical Applications and Benefits

Whether you're a professional mechanic or a DIY enthusiast, the Victron Argodiode Battery Isolator 140-3AC is an invaluable tool for maintaining your vehicle's electrical system. Its ability to prevent accidental drainage of the starter battery while using accessory batteries is particularly beneficial for those who rely on their vehicle's electrical systems for a variety of tasks. The isolator's compatibility with alternators that require DC voltage on the B+ output ensures seamless operation, even when the engine run/stop switch is engaged. With this isolator, you can enjoy peace of mind knowing that your battery system is optimized for performance and longevity.
