At 120W continuous output, it suits professional installations where ground loop elimination, noise reduction, or circuit separation is a priority.\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 loops and preventing interference between circuits.\u003c\/li\u003e\n  \u003cli\u003e48V input to 48V output configuration, suitable for same-voltage systems requiring electrical separation.\u003c\/li\u003e\n  \u003cli\u003e120W continuous output power at 2.5A output current.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range typical of the Orion-Tr series, accommodating real-world battery voltage fluctuations.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.5kg, suitable for installation in confined spaces or enclosures.\u003c\/li\u003e\n  \u003cli\u003eFixed output voltage with no need for external regulation in standard applications.\u003c\/li\u003e\n  \u003cli\u003eDesigned for use in 48V telecom, off-grid, marine and vehicle systems where circuit isolation is a wiring or safety requirement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eGalvanic isolation in a DC-DC converter means the input and output circuits share no direct electrical connection. This matters in practice when two 48V systems share a common chassis or negative rail but must remain electrically independent, for example when connecting a 48V house battery bank to a 48V auxiliary load that must not share a ground reference with the main system. Without isolation, ground loops can introduce noise, cause measurement errors, or create fault paths that are difficult to diagnose.\u003c\/p\u003e\n\n\u003cp\u003eThe Orion-Tr range uses a high-frequency transformer internally to achieve this isolation while maintaining a stable output voltage. The 48\/48-2.5A variant is the appropriate choice when the source and load voltages are nominally identical but the circuits must remain separated. It is not a voltage regulator in the traditional sense; it is a power transfer device with isolation as its primary function. At 120W, it covers a range of auxiliary loads including control systems, communications equipment, and instrumentation.\u003c\/p\u003e\n\n\u003cp\u003eThe unit is built to Victron's standard for DC conversion products, with protection against short circuit, over-temperature and reverse polarity on the input. It integrates straightforwardly into existing 48V architectures without requiring additional filtering or conditioning in most applications.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI484810110\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: 2.5A\u003c\/li\u003e\n  \u003cli\u003eOutput power: 120W continuous\u003c\/li\u003e\n  \u003cli\u003eIsolation: Galvanic (transformer-isolated)\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.5kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076016786\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eIsolating 48V auxiliary circuits from a main 48V battery bank in off-grid systems.\u003c\/li\u003e\n  \u003cli\u003ePowering 48V communications or control equipment from a 48V traction or house battery where ground separation is required.\u003c\/li\u003e\n  \u003cli\u003eMarine installations where galvanic isolation is required to prevent corrosion caused by stray currents.\u003c\/li\u003e\n  \u003cli\u003eTelecom and industrial enclosures requiring electrically separated 48V supply rails.\u003c\/li\u003e\n  \u003cli\u003eVehicle conversions and electric vehicle auxiliary systems with 48V architectures.\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\/48-2.5A (120W) 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 familiar with DC power systems. Ensure correct fusing on both the input and output sides in accordance with the wire gauge used. In marine applications, follow NMEA or flag-state wiring standards for isolated circuits. Verify that the input voltage range of the unit is compatible with the actual operating voltage of your battery system, including charge voltages at the top of the charge cycle. Do not exceed the rated output current of 2.5A continuously.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60227839689038,"sku":"ORI484810110","price":49.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI484810110_-_Orion-Tr_48-48-2_5A_120W_Isolated_DC-DC_converter.webp?v=1785165050","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-48-48-2-5a-120w-isolated-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
