    Argo FET Battery Isolator - 200AMP - 2 BatteriesSimilarly to diode battery isolators, FET 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 diode battery isolators, FET 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.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.

    Galvonic Isolator VDI-32A 32A Max Waterproof (Potted)The 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 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.Terminal posts are 6mm (1.4")This item is not ABYC A-28 approvedPlease contact your dealer for any returns, repairs or support issues related to this product.

    GI-30-FS Galvanic Isolator 30A Fail SafeInstalling the Galvanic Isolator between the AC safety ground and DC bonding system blocks most of the low-voltage currents and corrosive action seen on the vital metallic components in the saltwater. With the low voltage current blocked, the galvanic corrosion effect on the sacrificial anodes is significantly reduced, while the integrity of the critical safety ground path is maintained. This means a significant saving in boat haul-out fees and zinc replacement costs. For additional safety, all units feature a large capacitor, providing a secondary low-impedance path for sending AC current to the ground.Newmar’s latest galvanic isolator meets the latest ABYC A-28 2019 requirements, including being a failsafe. This design can meet the strictest temperature and current tests to create a robust solution for galvanic protection.Features: Protects against corrosion Maintains a safe environment Certified to the UL1500 standard for Ignition Protection Tested to a 50 degrees C ambient temperature The 30A fail-safe feature ensures ground maintenance Connection in the event of isolator failure Specifications: Shore Power Voltage: 115–230V    Maximum Short Circuit: 5000 Amps Stray Current Protection: Up to 1.4 VDC Dimensions (LxWxH): 200 x 189 x 68.5 mm This product may not be returned to the original point of purchase.

    12 in stock

    Argodiode Battery Isolator 80-2SC - 2 Batteries - 80AArgodiode Battery Isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries. Discharging the accessory battery for example will not result in also discharging the starter battery. Low voltage drop due to the use of high-efficiency Schottky diodes.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 of 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. Simply inserting the isolator in the cabling between the alternator and the batteries will slightly reduce charge voltage. The result can be that batteries are not charged to the full 100% and age prematurely. Alternator energize input Some alternators need DC voltage on the B+ output to start charging. Obviously, DC will be present when the alternator is directly connected to a battery. Inserting a Diode or FET splitter will however prevent any return voltage/current from the batteries to the B+, and the alternator will not start. The new ‘AC’ diode isolators feature a special current limited energize input that will power the B+ when the engine run/stop switch is closed.Please contact your dealer for any returns, repairs or support issues related to this product.
