It is suited to professional off-grid, marine, vehicle and industrial installations where two separate 48V systems must be connected without a shared ground reference.\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, eliminating ground loop issues and protecting sensitive equipment on either circuit.\u003c\/li\u003e\n  \u003cli\u003e48V input to 48V output at up to 8A continuous output current, delivering 380W of regulated DC power.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range typical of the Orion-Tr series, accommodating real-world battery voltage fluctuations across charge and discharge cycles.\u003c\/li\u003e\n  \u003cli\u003eCompact, enclosed aluminium housing with a weight of 1.8kg, suitable for fixed installation in confined spaces.\u003c\/li\u003e\n  \u003cli\u003eDesigned for continuous duty, making it appropriate for permanent installations rather than occasional or intermittent use.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron's broader 48V system ecosystem, including lithium and lead-acid battery banks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eGalvanic isolation is the key distinction of the Orion-Tr range over non-isolated DC-DC converters. When two battery systems share a common ground, faults, leakage currents and noise can pass between them. The Orion-Tr's transformer-based isolation breaks this path entirely, which matters in applications such as split charging on vehicles with sensitive electronics, marine installations with corrosion concerns, or industrial systems where regulatory or safety requirements demand isolated circuits.\u003c\/p\u003e\n\n\u003cp\u003eThe 48\/48-8A variant maintains the same nominal voltage on both sides, which may seem counterintuitive for a converter. In practice, this is used where a regulated, isolated 48V supply is needed from a 48V source that may vary in voltage. Battery voltage under load or during charging can swing considerably, and the Orion-Tr conditions that input into a stable, regulated output voltage. This protects downstream loads and ensures consistent performance regardless of the state of charge of the source battery.\u003c\/p\u003e\n\n\u003cp\u003eAt 380W continuous output, this unit is appropriate for powering 48V loads such as DC equipment, secondary battery banks or auxiliary systems. The enclosed housing and passive cooling design keep installation straightforward, with no fan noise or moving parts to maintain.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI484841110\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 48V nominal\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 48V nominal\u003c\/li\u003e\n  \u003cli\u003eOutput current: 8A continuous\u003c\/li\u003e\n  \u003cli\u003eOutput power: 380W\u003c\/li\u003e\n  \u003cli\u003eIsolation: Galvanic (transformer-based)\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.8kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076038894\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSplit charging between two isolated 48V battery banks in off-grid or vehicle installations.\u003c\/li\u003e\n  \u003cli\u003eMarine DC systems where galvanic isolation is required to prevent corrosion between hull and battery circuits.\u003c\/li\u003e\n  \u003cli\u003eIndustrial equipment requiring a regulated, isolated 48V supply from a 48V bus.\u003c\/li\u003e\n  \u003cli\u003eTelecommunications and data equipment powered from a 48V battery system where isolation from the source is specified.\u003c\/li\u003e\n  \u003cli\u003eAuxiliary power supply in electric vehicle conversions or specialist vehicles with dual 48V systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Orion-Tr 48\/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\u003eInstallation should be carried out by a qualified electrician or systems integrator with experience in DC power systems. Ensure input and output wiring is correctly rated for the current and voltage involved, and that appropriate fusing is fitted on both the input and output sides. Verify polarity before energising the unit. For marine installations, follow NMEA or flag state wiring standards as applicable. Do not install in locations exposed to water ingress or where ventilation is restricted to the point of heat build-up.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863712432462,"sku":"ORI484841110","price":155.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI484841110_-_Orion-Tr_48-48-8A_380W_Isolated_DC-DC_converter.webp?v=1781183647","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-48-48-8a-380w-isolated-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
