It suits boats, RVs and trucks where one alternator has to charge an engine battery plus one or more house or thruster banks.\u003c\/p\u003e\u003cp\u003eTraditional split-charge diodes lose around a volt, which leaves house batteries undercharged, and compensating for that loss can overcharge the starter battery. The Pro Split R uses micro-processor controlled switching with almost no voltage drop, and it can briefly isolate a full engine battery so the alternator's regulator sees only the empty house bank and charges it harder. Sterling states it is not suitable for modern European vehicles or any vehicle with an advanced ECU; use a battery to battery charger there.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMicro-processor controlled zero-volt-drop splitting\u003c\/li\u003e\n\u003cli\u003eSends the most current to the bank that needs it\u003c\/li\u003e\n\u003cli\u003eTemporarily isolates a full engine battery so the house bank charges faster\u003c\/li\u003e\n\u003cli\u003eBlocks back-feed between banks under heavy load\u003c\/li\u003e\n\u003cli\u003eDisconnects the alternator if its own regulator fails, so batteries are not boiled\u003c\/li\u003e\n\u003cli\u003eIsolates any bank being back-fed a high voltage from a faulty charger\u003c\/li\u003e\n\u003cli\u003eLED display shows which channels are active\u003c\/li\u003e\n\u003cli\u003eFail-safe: engine battery and alternator stay connected if the unit fails, and the engine battery is charged first\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem voltage:\u003c\/strong\u003e 12V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax alternator output:\u003c\/strong\u003e 120A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery bank outputs:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 150 x 80 x 140 mm (5.9 x 3.1 x 5.5 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.6 kg (1.32 lb)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Sterling Power with Sterling Power's warranty.
