This isolator automatically manages charging from up to two alternators, ensuring each battery receives the appropriate charge level without overcharging or discharging into one another. It is compatible with 12-, 24-, or 36-volt negative ground DC systems, making it versatile for various electrical setups. Crafted with conservatively rated diodes and housed in a rustproof anodized aluminum heat sink case, this unit offers durability and efficient heat dissipation for reliable performance in demanding environments. Its robust construction supports continuous operation at voltages up to 48 volts DC, making it suitable for demanding applications where reliability is critical. The package includes stainless steel mounting hardware and protective covers for terminals to ensure safe and secure installation. The isolator features a maximum input capacity of 70 amps and is designed to operate effectively across a wide temperature range from -40°F to +176°F, accommodating extreme weather conditions. Its compact dimensions and lightweight design make it easy to install in tight spaces without compromising performance. The voltage drop at half load is approximately 0.7 volts, with an increase to 0.9 volts at full load, ensuring efficient energy transfer during operation. Note that this isolator requires an external excitation lead from the alternator, so it is not compatible with self-exciting alternators. Proper compatibility should be confirmed with your alternator manufacturer to ensure optimal functionality. This product is intended for professional installation and should be handled with care to maintain safety and performance standards. For any issues or concerns, contact the manufacturer directly, as returns to the original retailer may not be possible. Ideal for marine, RV, or utility vehicles, the Newmar Power 2-3-70 Battery Isolator ensures your batteries are charged efficiently and safely, providing peace of mind during extended trips or demanding operational conditions.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eConservatively rated diodes and rustproof anodized aluminum heat sink case for durability and efficient heat dissipation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty construction suitable for continuous operation in demanding environments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRated for systems up to 48 volts DC with negative ground, ensuring compatibility with various electrical setups\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes stainless steel mounting hardware and protective terminal covers for safe installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMaximum input capacity of 70 amps to handle multiple battery charging needs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOperates effectively across a temperature range from -40°F to +176°F for versatile outdoor use\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for 2 alternator sources and up to 3 battery banks, optimizing charging management\u003c\/li\u003e\u003c\/ul\u003e","brand":"Newmar Power","offers":[{"title":"Default Title","offer_id":44624003268650,"sku":"102299","price":280.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/102299XL.jpg?v=1785203051","url":"https:\/\/atticusgoods.com\/products\/newmar-power-2-3-70-battery-isolator-for-dual-battery-systems","provider":"Atticus Goods","version":"1.0","type":"link"}
