It suits vehicles, boats and off-grid systems where two battery banks need to stay electrically separate from one another.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic isolation\u003c\/strong\u003e, transformer-based, so the input and output share no common electrical path, preventing ground loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConversion\u003c\/strong\u003e, 24V input to 12V output at 9A continuous, up to 110W.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide input tolerance\u003c\/strong\u003e, copes with the normal voltage swing of a real 24V battery bank during charge and discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact build\u003c\/strong\u003e, weighs 0.5kg, small enough for panel boards, lockers and engine bays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStable regulated output\u003c\/strong\u003e, 12V loads stay protected from fluctuations on the 24V side.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully encapsulated\u003c\/strong\u003e, protection against vibration and moisture, suited to mobile and marine environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003eThe Orion-Tr range uses an isolated transformer topology. In dual-battery setups this stops a 24V service bank from creating a ground fault path when it feeds 12V accessories, and it keeps a fault on the 12V side from feeding back into the 24V bank.\u003c\/p\u003e\u003cp\u003eAt 110W, it's suited to loads like lighting circuits, control electronics, communications gear, or charging a smaller 12V battery from a larger 24V bank. It is a converter for continuous load supply, not a battery-to-battery charger. If you need to charge a 12V battery from a 24V source with proper charge profiles, the Orion-Tr Smart range is the correct product instead.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePowering 12V accessories and control circuits from a 24V vehicle or coach electrical system.\u003c\/li\u003e\n\u003cli\u003eMarine installations where a 24V bank needs to run isolated 12V instrument or navigation circuits.\u003c\/li\u003e\n\u003cli\u003eOff-grid cabins and mobile setups running a 24V bank alongside a 12V supply rail.\u003c\/li\u003e\n\u003cli\u003eTelecoms and industrial enclosures needing a stable isolated 12V supply from a 24V DC bus.\u003c\/li\u003e\n\u003cli\u003eDual-battery systems where electrical isolation between banks is a safety requirement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1x Victron Orion-Tr 24\/12-9A (110W) Isolated DC-DC Converter\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit this with correct fusing on both input and output sides, matched to the wire gauge used, in a ventilated location away from direct water ingress.
