It is designed for professional mobile, marine and off-grid installations where two battery banks must remain electrically isolated from one another.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanic isolation between input and output, preventing ground loops and protecting sensitive electronics in dual-battery systems.\u003c\/li\u003e\n  \u003cli\u003e12V input to 48V output conversion at up to 8A continuous output current, rated at 380W.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range suitable for 12V lead-acid and lithium battery systems with varying state of charge.\u003c\/li\u003e\n  \u003cli\u003eOutput voltage is adjustable, allowing fine-tuning to match the charge requirements of the destination battery bank.\u003c\/li\u003e\n  \u003cli\u003eCompact, enclosed metal housing rated for demanding environments, with a weight of 1.8 kg.\u003c\/li\u003e\n  \u003cli\u003eCan be used in parallel with additional Orion-Tr units to increase total output current where higher power is required.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron's broader ecosystem, including integration into systems monitored via VE.Smart Networking (where supported by the wider installation).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr isolated series uses a transformer-based topology to provide true galvanic isolation between the source and destination circuits. This is a practical requirement in many marine and vehicle installations, where chassis grounds, shore power references or multiple battery banks would otherwise create unwanted current paths or interference. The isolation also adds a layer of protection against fault propagation between battery banks.\u003c\/p\u003e\n\n\u003cp\u003eStepping up from 12V to 48V makes this converter well suited to installations where a 48V service bank, traction system or telecom load must be charged or powered from a 12V alternator or house battery. The adjustable output voltage means the unit can be set to deliver the correct absorption or float voltage for the connected battery chemistry, whether lead-acid, AGM, gel or lithium. At 380W continuous, the 8A output is sufficient for moderate charging duties or powering 48V DC loads directly.\u003c\/p\u003e\n\n\u003cp\u003eThe Orion-Tr 12\/48-8A can be mounted in any orientation and does not require forced cooling under normal operating conditions. Multiple units can be wired in parallel on the output side if the application demands more than 8A at 48V, giving installers a scalable solution without requiring a larger single converter.\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;\"\u003eORI124838110\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eInput Voltage (nominal)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e12V DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Voltage (nominal)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e48V DC (adjustable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Current (maximum)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eRated Output Power\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e380W\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eIsolation\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGalvanic (transformer-based)\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;\"\u003e1.8 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;\"\u003e8719076063650\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\u003eCharging a 48V lithium or lead-acid battery bank from a 12V vehicle or vessel alternator system.\u003c\/li\u003e\n  \u003cli\u003ePowering 48V DC telecom or data equipment from a 12V house battery in off-grid cabins or remote installations.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-battery installations where galvanic isolation is required to prevent corrosion and ground loop issues.\u003c\/li\u003e\n  \u003cli\u003eMotorhome and campervan conversions with mixed-voltage DC systems requiring isolated voltage step-up.\u003c\/li\u003e\n  \u003cli\u003eIndustrial and mobile applications where a 48V load must be fed from a 12V source without a shared ground reference.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x Victron Orion-Tr 12\/48-8A (380W) Isolated DC-DC Converter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis converter handles significant DC currents on the 12V input side. Correct cable sizing and fusing on both the input and output circuits is essential. Installation should be carried out by a qualified electrician or experienced marine\/vehicle systems installer familiar with DC power systems. Ensure the input supply is adequately protected and that the output voltage is set correctly for the connected battery chemistry before commissioning. In marine installations, follow NMEA or relevant national wiring standards for DC systems.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60190996365646,"sku":"ORI124838110","price":163.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI124838110_-_Orion-Tr_12-48-8A_380W_Isolated_DC-DC_converter.webp?v=1784715774","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-12-48-8a-380w-isolated-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
