    1-3-70 Battery IsolatorThis heavy-duty isolator allows charging multiple batteries automatically from one or two alternators and prevents the discharge or ‘dumping” of one battery into another. Each battery is charged according to its need without overcharging and is rated for 12-, 24-, or 36-volt negative ground DC systems. Features: Conservatively rated diodes and a rustproof anodized aluminum heat sink case. Heavy-duty construction Rated for systems up to 48 volts DC, negative ground Rust-proof anodized aluminum case Stainless steel mounting hardware is provided Protective covers are provided for terminals Specifications: Alternator Sources: 1 Battery Bank: 3     Max. Amperage Input Capacity: 70 Stud Terminal Size: 6mm     Dimensions (L x W x H): 3.25 x 4.5 x 3.1 inches Weight: 2 lbs. Operating Temperature: -40 to +80 degrees Duty Cycle: Continuous rating to 50 degrees C Derate linearly to 70% @ 80 degrees C. Temp. Rise: 5 degrees C at full rated current (mount vertically for optimum cooling) Voltage Drop: 0.7V @ 50% load, 0.9V @ full load *Note: These battery isolators are not compatible with self-exciting alternators. The alternator must have an external excitation lead. Please consult the manufacturer of your alternator if you are unsure of your configurationThis product may not be returned to the original point of purchase. Please contact the manufacturer directly with any issues or concerns. Quick Guide (pdf)

    Galvanic Isolator VDI-16A, 16 AMP Max Waterproof PottedThe galvanic isolator prevents electrolytic corrosion. It blocks low-voltage DC currents that enter your boat via the shore power earth wire. These currents can cause corrosion to the boat’s underwater metals, like the hull, propeller, shaft, and so on.The galvanic isolator consists internally of two diodes which are connected in an anti-parallel fashion. When they are connected in this way, the diodes allow current in both directions but only above a certain threshold voltage. The voltage at which diodes conduct is about 1.4 Vdc.The isolator is installed directly behind your boat's 120V - 230V connection. The forward voltage from the galvanic isolator is higher than the potential difference between metals. As a result, this voltage will not allow conduction and as such, the galvanic isolator will prevent any electrolytic current. However, if there is a (higher) error voltage in the AC circuit, the diodes will allow current through and the residual-current device will break the circuit.Please contact your dealer for any returns, repairs or support issues related to this product.

    Argofet Battery Isolator 100-3 3 Batteries - 100AMPSimilarly to Argodiode battery isolators, Argofet isolators allow simultaneous charging of two or more batteries from one alternator (or a single output battery charger), without connecting the batteries together. In contrast with Argodiode battery isolators, Argofet isolators have virtually no voltage loss. Voltage drop is less than 0,02 Volt at low current and averages 0,1 Volt at higher currents.

    200A, 40V 3-Bank Ideal Battery IsolatorFeatures: Waterproof Expoxy Sealed Construction Easy Connection Most Efficient use of Available Alternator Output Maximize Battery Performance Three year parts and labour warranty Analytic Systems introduces the IBI (Ideal Battery Isolator) for 1, 2 and 3 bank battery systems, allowing all the batteries to be fully charged from a single alternator while maintaining electricalisolation between the battery banks or between a vehicle and trailer.Ideal Diode technology uses MosFet Transistors and control circuitry to replace the diode used in a traditional battery isolator and reduces the voltage drop across the isolator to a mere 160 millivolts at 200 Amps of charging current and essentially zero volts at low current, so all the power of the alternator is applied to the batteries ensuring a full recharge every time.While the Ideal Battery Isolator is designed to be used with an alternator, it can also be used to convert a single bank battery charger to a 2 or 3 bank charger or as a pure diode between a vehicle and trailer or other remote load.

    Argo Diode Battery Isolator - 160AMP - 2 BatteriesDiode battery isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Discharging the accessory battery for example will not result in also discharging the starter battery. The Argo Battery Isolators feature a low voltage drop thanks to the use of Schottky diodes: at low current the voltage drop is approximately 0,3 V and at the rated output approximately 0,45 V. All models are fitted with a compensation diode that can be used to slightly increase the output voltage of the alternator. This compensates for the voltage drop over the diodes in the isolator.Warranty InfoWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
