It suits vehicles, vessels, off-grid systems and industrial equipment where ground loop issues or safety isolation matter.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic isolation\u003c\/strong\u003e between input and output, reducing ground loop interference and improving safety in dual-battery or mixed-system installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput power\u003c\/strong\u003e, 280W continuous at 6A on a 48V output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide input range\u003c\/strong\u003e handles fluctuating 48V bus voltages from solar, battery or alternator sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing\u003c\/strong\u003e, compact enclosed aluminium casing weighing 1.3 kg, suitable for panel or DIN-rail adjacent mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable output\u003c\/strong\u003e via an internal potentiometer, allowing the voltage to be set to match a specific battery or load.\u003c\/li\u003e\n\u003cli\u003eHigh conversion efficiency, reducing heat generation and energy loss in DC distribution systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThis converter uses a transformer-based topology for true galvanic isolation: input and output circuits share no direct electrical connection. That matters in marine and vehicle installations where chassis grounds differ between systems, and anywhere fault current paths need to be controlled. The 48V-in to 48V-out configuration actively regulates the output, which can be set independently of the input rather than simply passing it through.\u003c\/p\u003e\u003cp\u003eAt 280W and 6A, the unit suits supplying 48V DC loads or maintaining a secondary 48V battery bank where the primary and secondary systems must stay isolated. Because output voltage is adjustable, it can be set to a float or absorption-level voltage for a secondary battery without an additional charge controller. That flexibility is useful on dual-bank lithium or lead-acid setups.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDual 48V battery bank systems requiring isolation between primary and secondary banks.\u003c\/li\u003e\n\u003cli\u003eMarine installations needing galvanic isolation to prevent corrosion and ground loop faults.\u003c\/li\u003e\n\u003cli\u003eVehicle and motorhome builds with separate 48V chassis and habitation circuits.\u003c\/li\u003e\n\u003cli\u003eOff-grid solar systems supplying isolated 48V DC loads from a main 48V battery bus.\u003c\/li\u003e\n\u003cli\u003eIndustrial DC distribution panels where circuits must stay electrically separated.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Orion-Tr 48\/48-6A (280W) Isolated DC-DC Converter\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFitting should be carried out by a qualified electrician or an experienced system integrator familiar with DC power systems. Wiring must be correctly rated for the current and voltage involved. Marine installs should follow applicable NMEA or ISO wiring standards, and vehicle installs should keep the converter away from moisture and excessive heat. Only adjust the output potentiometer with the unit powered down, unless confident working on live low-voltage DC circuits.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095575490848,"sku":"ORI484828110","price":93.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-ori484828110-1.webp?v=1785754156","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-orion-48-48-dc-converter","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
