It suits vehicles, boats, caravans and off-grid setups where two battery banks need to stay electrically separate.\u003c\/p\u003e\u003ch2\u003eKey features of this Victron DC-DC converter\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation\u003c\/strong\u003e, galvanic isolation between input and output, preventing ground loop issues and protecting the secondary circuit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e, 110W continuous, 9A at 12V output from a 12V input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput range\u003c\/strong\u003e, wide input voltage range copes with fluctuating alternator or solar charge voltages without shutting down.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e, compact and lightweight at 0.5 kg, fitting confined spaces such as vehicle cabinets or marine bilge areas.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput voltage\u003c\/strong\u003e, fixed, giving a stable charge source for lead-acid and other 12V battery chemistries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuty\u003c\/strong\u003e, designed for continuous, permanent installation rather than occasional use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct overview\u003c\/h2\u003e\u003cp\u003eThe Orion-Tr range uses a transformer-based design for true galvanic isolation. This matters in dual-battery systems where the two banks serve different purposes, such as a starter battery and a leisure battery in a motorhome, or a bow thruster bank and a house bank on a boat. Without isolation, a fault on one circuit can spread to the other. This unit stops that happening.\u003c\/p\u003e\u003cp\u003eAt 110W and 9A, it is sized for moderate secondary battery charging. It maintains a leisure or auxiliary battery while the vehicle or vessel is running, without pulling excessive current from the primary source. The fixed output voltage needs no programming, so installation is simpler than with adjustable variants.\u003c\/p\u003e\u003cp\u003eThe aluminium enclosure dissipates heat without forced cooling in most applications. There is no minimum load requirement, so the converter can stay connected once the secondary battery is fully charged.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDual-battery systems in motorhomes, campervans and caravans where starter and leisure banks must stay isolated.\u003c\/li\u003e\n\u003cli\u003eMarine installations requiring isolation between engine start and house battery circuits.\u003c\/li\u003e\n\u003cli\u003eOff-grid cabins or vehicles where a secondary 12V load circuit must be kept separate from the primary supply.\u003c\/li\u003e\n\u003cli\u003eTelecommunications and instrumentation enclosures needing a clean, isolated 12V supply.\u003c\/li\u003e\n\u003cli\u003eAuxiliary battery charging in emergency and specialist vehicles.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Victron Orion-Tr 12\/12-9A (110W) Isolated DC-DC Converter\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFitting should be done by a qualified electrician or experienced 12V systems installer. Size and fuse the cables on both input and output sides according to the unit's current rating. Input and output circuits must not share a common ground if galvanic isolation is to be kept intact. Marine installations should follow the relevant BMEA or IEC wiring standards. This unit is not intended for grid-connected or mains-voltage use.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":52095601705248,"sku":"ORI121210110","price":51.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1010\/8148\/1504\/files\/ledandsolar-ori121210110-1.webp?v=1785754887","url":"https:\/\/www.ledandsolar.co.uk\/products\/victron-orion-tr-isolated-dc-dc-converter","provider":"LED \u0026 Solar","version":"1.0","type":"link"}
