It is suited to marine, vehicle and off-grid installations where independent battery banks must be charged in parallel without risk of cross-discharge.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharges three independent battery banks from a single input source at up to 200A continuous current.\u003c\/li\u003e\n  \u003cli\u003eMOSFET technology eliminates the 0.6V to 0.7V voltage drop associated with conventional diode isolators, so batteries receive the full alternator or charger output voltage.\u003c\/li\u003e\n  \u003cli\u003eIntegrated voltage equalisation circuit ensures the alternator regulator senses the correct battery voltage, preventing undercharging.\u003c\/li\u003e\n  \u003cli\u003eCompact, aluminium heatsink construction dissipates heat without requiring a fan or active cooling.\u003c\/li\u003e\n  \u003cli\u003eEach output is fully isolated, preventing discharge from one battery bank to another when the input source is disconnected.\u003c\/li\u003e\n  \u003cli\u003eSuitable for 12V, 24V and 48V battery systems.\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.37 kg.

In practice, this means batteries are chronically undercharged unless the alternator regulator is manually adjusted. The Argofet 200-3 uses MOSFET field-effect transistors instead of diodes. The voltage drop across a MOSFET in conduction is negligible, so the full charge voltage reaches each battery bank without modification to the charging source.\u003c\/p\u003e\n\n\u003cp\u003eThe unit includes a dedicated voltage sensing wire that feeds the actual battery voltage back to the alternator regulator. This is important in systems where the regulator would otherwise sense voltage at the alternator output rather than at the battery terminals. Without this correction, even a low-drop isolator can result in inaccurate charge termination. The Argofet handles this automatically, making it straightforward to integrate into existing alternator charging circuits.\u003c\/p\u003e\n\n\u003cp\u003eWith a 200A continuous rating across three outputs, the Argofet 200-3 covers the majority of marine and commercial vehicle applications. The aluminium body acts as a passive heatsink and should be mounted on a flat, thermally conductive surface for best performance at high sustained currents.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eARG200301020R\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eMaximum Input Current\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e200A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eNumber of Outputs\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e3\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eIsolator Type\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eMOSFET (FET)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eCompatible Voltages\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e12V, 24V, 48V\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e1.37 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076019169\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMarine vessels with separate starter, domestic and bow thruster battery banks.\u003c\/li\u003e\n  \u003cli\u003eMotorhomes and campervans requiring isolation between the vehicle starter battery and one or more leisure battery banks.\u003c\/li\u003e\n  \u003cli\u003eCommercial vehicles with auxiliary battery systems for refrigeration, tail lifts or other equipment.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins or vehicles where a single alternator or DC charger must serve multiple battery banks independently.\u003c\/li\u003e\n  \u003cli\u003eRetrofit installations replacing diode isolators where voltage drop has caused persistent undercharging.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eVictron Argofet 200-3 FET battery isolator unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Argofet 200-3 should be installed by a qualified electrician or marine electrical engineer familiar with high-current DC systems.
