ProMariner ProIsoCharge Battery Isolator: Advanced Power Management

The ProMariner ProIsoCharge Battery Isolator is a cutting-edge solution for ensuring optimal battery health and efficient power distribution in marine applications. This isolator is designed to deliver intelligent and zero voltage loss isolation, making it a game-changer in the industry. With its ability to charge up to three additional battery banks from a single alternator, it is particularly beneficial for dual engine applications. The ProIsoCharge250 1-3 model, part number 23123, is a testament to ProMariner's commitment to innovation and quality. Its all-in-one design eliminates the need for multiple voltage-sensitive relays, saving space, installation time, and cost.

Key Specifications and Technical Details

The ProIsoCharge250 1-3 model offers a robust 12V system with a maximum DC current of 250 Amps. It features one alternator input and two battery outputs, making it highly versatile for various marine setups. Measuring 6.95" in length, 5.875" in width, and 3.125" in height, this isolator is compact yet powerful. Weighing just 4 lbs, it is easy to install and maintain. Key features include intelligent alternator power distribution, zero voltage loss isolation, and advanced regulator readiness. The modular design ensures easy installation, and the product is ignition protected and waterproof to IP66 standards, providing long-lasting durability and safety.

Practical Applications and Benefits

The ProMariner ProIsoCharge Battery Isolator is an essential tool for boat owners looking to maximize their time on the water. Its intelligent charging capabilities ensure that fully charged batteries are taken off-line, providing priority charging to battery banks under load. This not only extends battery life but also enhances overall system performance. The real-time LED status indicators provide clear visibility into the charging status and any potential faults, such as high or low alternator output, over-voltage protection, and high voltage conditions. By eliminating the typical alternator voltage loss of 0.6VDC, the ProIsoCharge ensures faster charge times and fully charged batteries, allowing boat owners to enjoy more time boating and less time worrying about battery maintenance. With the ProNauticP Series, the ProIsoCharge offers the full benefit of shore power and on-the-water charging, making it an indispensable addition to any marine electrical system.
