It is designed for professional use in battery systems, vehicles, vessels and off-grid installations where two DC buses at different voltages must be kept electrically separate.\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 loads from input-side faults.\u003c\/li\u003e\n  \u003cli\u003e48V input to 24V output conversion at 5A continuous, delivering up to 120W of regulated DC power.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates real-world battery voltage fluctuations across 48V lead-acid and lithium systems.\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.5kg, suitable for installation in confined spaces such as panel enclosures, vehicle cabinets and marine switchboards.\u003c\/li\u003e\n  \u003cli\u003eFixed output voltage design provides a stable 24V supply to downstream loads without requiring manual adjustment.\u003c\/li\u003e\n  \u003cli\u003eVictron Orion-Tr range is widely used in professional off-grid, marine and vehicle installations, with a large installer base and established support ecosystem.\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. By using a transformer-based topology, the input and output circuits share no direct electrical connection. This matters in practice when the 48V source and the 24V load circuit have separate earthing references, or when you need to prevent fault currents from propagating between two battery banks. It is a standard requirement in many marine and vehicle installations.\u003c\/p\u003e\n\n\u003cp\u003eThe 48\/24-5A model is suited to applications where a 48V primary system needs to power a 24V auxiliary circuit: running 24V control electronics, communications equipment, lighting or instrumentation from a 48V battery bank without bridging the two systems electrically. At 120W continuous output, it covers a practical range of auxiliary loads without requiring a larger, more expensive converter.\u003c\/p\u003e\n\n\u003cp\u003eThe Orion-Tr series is built to operate in demanding environments. The unit is designed for permanent, fixed installation and should be mounted in a ventilated location. It does not include remote on\/off control or programmable output voltage in this variant, keeping the design straightforward for fixed-voltage applications.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI482410110\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 48V DC (nominal)\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 24V DC\u003c\/li\u003e\n  \u003cli\u003eOutput current: 5A continuous\u003c\/li\u003e\n  \u003cli\u003eOutput power: 120W\u003c\/li\u003e\n  \u003cli\u003eGalvanic isolation: Yes\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.5kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076016779\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePowering 24V auxiliary loads (control panels, instrumentation, lighting) from a 48V battery bank in off-grid systems.\u003c\/li\u003e\n  \u003cli\u003eMarine installations requiring isolated DC conversion between a 48V propulsion or house bank and a 24V electronics bus.\u003c\/li\u003e\n  \u003cli\u003eElectric and hybrid vehicles or specialist vehicles with a 48V main system and 24V accessory circuits.\u003c\/li\u003e\n  \u003cli\u003eTelecom and industrial enclosures where a 48V supply must feed isolated 24V equipment.\u003c\/li\u003e\n  \u003cli\u003eBattery system integration where two banks at different voltages must remain electrically isolated from one another.\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\/24-5A (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 input and output wiring is correctly rated for the voltages and currents involved, and that the unit is mounted in a location with adequate ventilation. For marine installations, follow applicable NMEA and flag-state wiring standards. For vehicle installations, observe relevant automotive or specialist vehicle electrical codes. This unit is not intended for grid-connected applications and does not require G98 or G99 compliance assessment.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":59863712334158,"sku":"ORI482410110","price":48.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI482410110_-_Orion-Tr_48-24-5A_120W_Isolated_DC-DC_converter.webp?v=1781183642","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-48-24-5a-120w-isolated-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
