It is designed for professional installations where electrical isolation between two DC systems is required, such as powering 12V auxiliary loads from a 48V battery bank or vehicle system.\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 eliminates ground loop issues and protects sensitive equipment from voltage spikes on the source circuit.\u003c\/li\u003e\n  \u003cli\u003e48V input to 12V output conversion at 20A continuous, delivering up to 240W of regulated DC power.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates real-world battery voltage fluctuations across 48V systems.\u003c\/li\u003e\n  \u003cli\u003eCompact, enclosed housing suitable for fixed installation in vehicles, vessels and off-grid enclosures.\u003c\/li\u003e\n  \u003cli\u003eOutput voltage is adjustable, allowing fine-tuning to suit specific load or charging requirements.\u003c\/li\u003e\n  \u003cli\u003eHigh conversion efficiency reduces heat generation and minimises power loss in the conversion stage.\u003c\/li\u003e\n  \u003cli\u003eVictron Orion-Tr range is widely used in marine, automotive and off-grid applications where dual-voltage DC architectures are common.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr isolated DC-DC converters differ from non-isolated units in that the input and output circuits share no common ground. This matters in practice when integrating a 12V auxiliary system into a 48V main system, particularly on vessels or vehicles where chassis grounds, bonding requirements and sensitive electronics make ground loops a genuine risk. The galvanic isolation barrier prevents fault currents from passing between the two circuits and allows each side to be referenced independently.\u003c\/p\u003e\n\n\u003cp\u003eAt 240W output, this unit is capable of running 12V lighting circuits, control electronics, communication equipment, water pumps and similar auxiliary loads directly from a 48V battery bank. The output voltage can be adjusted from its nominal 12V setting, which is useful when the converter is used to top-charge a 12V battery rather than simply power a fixed load. The unit does not require a remote on\/off connection to operate, though the Orion-Tr range supports this feature where wiring it in is practical.\u003c\/p\u003e\n\n\u003cp\u003eWeighing 1.3kg, the unit is straightforward to mount in a panel, enclosure or under a dashboard. It carries Victron's standard build quality and is backed by their global support network, making it a practical choice for installers who need a reliable, isolated voltage conversion solution without over-specifying the installation.\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  \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  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eORI481224110\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;\"\u003e48V 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;\"\u003e12V DC\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;\"\u003e20A\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Power (maximum)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e240W\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 (isolated)\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;\"\u003e1.3 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;\"\u003e8719076035282\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePowering 12V auxiliary loads (lighting, pumps, control systems) from a 48V off-grid battery bank.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring galvanic isolation to prevent corrosion and protect onboard electronics.\u003c\/li\u003e\n  \u003cli\u003eElectric vehicle or converted vehicle builds with a 48V main bus and 12V accessory circuits.\u003c\/li\u003e\n  \u003cli\u003eTelecom and industrial enclosures where isolated DC power rails are required for control equipment.\u003c\/li\u003e\n  \u003cli\u003eBackup power systems combining a 48V battery system with legacy 12V loads or instrumentation.\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 48\/12-20A (240W) 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 should be installed by a qualified electrician or experienced systems integrator familiar with DC power systems. Ensure correct fusing on both the input and output sides in accordance with the wire gauges used. On marine installations, follow NMEA or flag-state wiring standards as applicable.
