It efficiently distributes charging current from an alternator or charger to up to three independent battery banks while ensuring electrical isolation to prevent mutual discharge. This model is ideal for installations requiring stable power supply and enhanced battery protection.\n\u003c\/p\u003e\n\n\u003ch3\u003eTechnology and performance\u003c\/h3\u003e\n\u003cp\u003e\n    Part of Mastervolt’s BI range, the \u003cstrong\u003eBI 1203-S\u003c\/strong\u003e uses conventional diode technology. It differs from models without the \"S\" suffix by integrating a compensation diode. This feature is critical as it automatically compensates for the voltage drop (approximately 0.6 V) inherent to diodes when the distributor is paired with \u003cstrong\u003eMastervolt Mass\u003c\/strong\u003e battery chargers or \u003cstrong\u003eAlpha Pro\u003c\/strong\u003e charge regulators. This ensures batteries receive their full charging voltage, optimizing their lifespan and performance. In comparison, other \u003cstrong\u003eMastervolt\u003c\/strong\u003e solutions like the \u003cstrong\u003eCharge Mate\u003c\/strong\u003e focus on connecting\/disconnecting two batteries, while the \u003cstrong\u003eBattery Watch\u003c\/strong\u003e provides monitoring and a main switch function. The \u003cstrong\u003eBI 1203-S\u003c\/strong\u003e handles a maximum output current of 80 A for a charger and 120 A for an alternator, with an input voltage range of 6 to 50 VDC, and ground isolation exceeding 500V at 60Hz.\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and installation\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eMastervolt BI 1203-S\u003c\/strong\u003e features a compact design with dimensions of 207 x 140 x 80 mm and a weight of 1.3 kg, making it easy to integrate into confined spaces on board. Its construction is tailored for marine environments: it is made from fully corrosion-resistant materials, includes an aluminum heat sink, and electronic components encapsulated in synthetic materials. This robustness ensures exceptional durability in the most demanding maritime conditions, with an operating temperature range from -40 to +120°C. Installation is simplified by synthetic end plates with terminals, and sturdy threaded connectors with nuts and locking washers that guarantee reliable and quick connections. For \"S\" models, connecting a current source probe (sense-connection) is essential to activate automatic voltage drop compensation.\n\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":53723890188628,"sku":"83012031","price":152.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/repartiteur-de-charge-bi-1203-s_83012031-3.jpg?v=1778089373","url":"https:\/\/skysat.fr\/en-gb\/products\/mastervolt-load-distributor-bi-1203s-120a-12-24v","provider":"Skysat","version":"1.0","type":"link"}
