It is designed for professional dual-battery and multi-voltage systems where electrical isolation between circuits is a requirement, not an option.\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 issues and protects sensitive electronics in dual-bus systems.\u003c\/li\u003e\n  \u003cli\u003eBluetooth built-in via VictronConnect allows configuration, monitoring and firmware updates without additional hardware.\u003c\/li\u003e\n  \u003cli\u003eInput voltage range suited to 24V lead-acid and lithium battery banks, with adjustable input voltage thresholds to protect the source battery.\u003c\/li\u003e\n  \u003cli\u003eAdaptive charging algorithm supports lithium (LiFePO4), AGM, gel and flooded battery chemistries on the output side.\u003c\/li\u003e\n  \u003cli\u003eEngine-detection feature prevents the charger from drawing down the starter battery when the alternator is not running.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable enclosure rated for demanding installation environments.\u003c\/li\u003e\n  \u003cli\u003e400W continuous output power with high conversion efficiency, minimising heat generation in enclosed spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Orion-Tr Smart range uses galvanic isolation to keep the input and output circuits electrically separate. This matters in vehicles, vessels and off-grid systems where two battery banks share a chassis ground, because without isolation a direct DC-DC converter can create unwanted current paths that cause corrosion, interference or safety hazards. The isolation transformer inside this unit eliminates that risk entirely.\u003c\/p\u003e\n\n\u003cp\u003eConfiguration is handled through the VictronConnect app over Bluetooth. Installers can set the input voltage lockout threshold (to prevent the charger from flattening the source bank), select the correct charge profile for the output battery chemistry, and monitor real-time current, voltage and charge state. No additional interface hardware or proprietary dongles are required.\u003c\/p\u003e\n\n\u003cp\u003eAt 400W continuous, this unit is well suited to 24V-to-48V step-up applications in electric vehicles, marine dual-bank systems, and off-grid installations where a 24V generation or storage source needs to feed a 48V load or battery. The 8.5A output current is fixed by the converter topology, so system designers should verify this matches the charge acceptance rate of the target battery bank.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eORI244840120\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eInput Voltage (nominal)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e24V DC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Voltage (nominal)\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e48V DC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Current\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8.5A\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eContinuous Output Power\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e400W\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eIsolation\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGalvanic (transformer-based)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eConnectivity\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eBluetooth (VictronConnect)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e1.8 kg\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076065579\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a 48V lithium or lead-acid service battery from a 24V alternator or starter battery bank in commercial vehicles.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-bank systems where galvanic isolation is required to prevent stray current corrosion.\u003c\/li\u003e\n  \u003cli\u003eOff-grid installations stepping up from a 24V solar or battery source to a 48V battery or load bus.\u003c\/li\u003e\n  \u003cli\u003eElectric vehicle auxiliary systems requiring isolated voltage conversion between bus voltages.\u003c\/li\u003e\n  \u003cli\u003eTelecom and industrial DC power systems with mixed 24V and 48V distribution rails.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOrion-Tr Smart 24\/48-8.5A Isolated DC-DC Charger (ORI244840120)\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.
