It suits marine, vehicle and off-grid systems where two 12V battery banks need to stay independent.\u003c\/p\u003e\u003ch2\u003eVictron DC-DC converter key features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation\u003c\/strong\u003e, galvanic, transformer-based, separating input and output circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput current\u003c\/strong\u003e, 18A continuous at 12V.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput power\u003c\/strong\u003e, 220W.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e, 1.15 kg.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign\u003c\/strong\u003e, solid-state with no moving parts.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy isolation matters\u003c\/h2\u003e\u003cp\u003eNon-isolated DC-DC converters can let fault currents pass between battery banks and introduce ground loops that interfere with audio, navigation or communication equipment. The Orion-Tr's transformer-based topology keeps the two circuits fully separate, avoiding that shared ground reference altogether.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCharging a 12V service battery from a 12V starter battery on boats, motorhomes and campervans.\u003c\/li\u003e\n\u003cli\u003eSupplying a 12V DC load circuit from a separate battery bank where ground loop prevention matters.\u003c\/li\u003e\n\u003cli\u003eOff-grid cabins and vehicles with two independently earthed 12V systems.\u003c\/li\u003e\n\u003cli\u003eCommercial vehicle auxiliary power systems needing regulated 12V output.\u003c\/li\u003e\n\u003cli\u003eMarine installations where isolation between battery banks is required by wiring standards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation notes\u003c\/h2\u003e\u003cp\u003eFit this converter with correctly rated wiring and fusing on both input and output circuits, in a ventilated location away from water ingress.
