It suits professional installations in vehicles, vessels, off-grid systems and industrial equipment where ground loop issues or safety separation are a concern.\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 interference and improves safety in dual-battery or mixed-system installations.\u003c\/li\u003e\n  \u003cli\u003e280W continuous output power at 6A on a 48V output, suitable for powering 48V loads or charging a secondary 48V battery bank.\u003c\/li\u003e\n  \u003cli\u003eWide input voltage range accommodates fluctuating 48V bus voltages typical of solar, battery and alternator sources.\u003c\/li\u003e\n  \u003cli\u003eCompact, enclosed aluminium housing with a weight of 1.3 kg, suitable for panel or DIN-rail adjacent mounting in confined spaces.\u003c\/li\u003e\n  \u003cli\u003eOutput voltage is adjustable via an internal potentiometer, allowing fine-tuning to match specific battery or load requirements.\u003c\/li\u003e\n  \u003cli\u003eHigh conversion efficiency reduces heat generation and minimises energy losses in DC distribution systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr range uses a transformer-based topology to provide true galvanic isolation, meaning the input and output circuits share no direct electrical connection. This is particularly important in marine and vehicle installations where chassis grounds differ between systems, and in any application where fault current paths need to be controlled. The 48V-in to 48V-out configuration is not a simple pass-through: the converter actively regulates the output voltage, which can be set independently of the input.\u003c\/p\u003e\n\n\u003cp\u003eAt 280W and 6A output, this unit is well suited to supplying 48V DC loads or maintaining a secondary 48V battery in systems where the primary and secondary banks must remain isolated. The adjustable output voltage means it can be configured to deliver a float or absorption-level voltage to a secondary battery without requiring an additional charge controller. Installers working on dual-bank lithium or lead-acid systems will find this flexibility useful in practice.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: ORI484828110\u003c\/li\u003e\n  \u003cli\u003eInput voltage: 48V nominal\u003c\/li\u003e\n  \u003cli\u003eOutput voltage: 48V nominal (adjustable)\u003c\/li\u003e\n  \u003cli\u003eOutput current: 6A\u003c\/li\u003e\n  \u003cli\u003eOutput power: 280W\u003c\/li\u003e\n  \u003cli\u003eIsolation: Galvanic (transformer isolated)\u003c\/li\u003e\n  \u003cli\u003eWeight: 1.3 kg\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076035305\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDual 48V battery bank systems requiring isolation between primary and secondary banks.\u003c\/li\u003e\n  \u003cli\u003eMarine installations where galvanic isolation is required 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 input and output circuits must be electrically separated.\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 Orion-Tr 48\/48-6A (280W) 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 experienced system integrator familiar with DC power systems. Ensure input and output wiring is correctly rated for the current and voltage involved. In marine applications, follow applicable NMEA or ISO wiring standards. For vehicle installations, verify that the converter mounting location is protected from moisture and excessive heat. The output voltage adjustment potentiometer should only be set with the unit powered down unless the installer is confident working on live low-voltage DC circuits.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":60227839852878,"sku":"ORI484828110","price":88.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/VoltaconSolar_-_ORI484828110_-_Orion-Tr_48-48-6A_280W_Isolated_DC-DC_converter.webp?v=1785165057","url":"https:\/\/voltaconsolar.com\/products\/victron-orion-tr-48-48-6a-280w-isolated-dc-dc-converter","provider":"VoltaconSolar","version":"1.0","type":"link"}
