It is aimed at professional installers working on commercial vehicles, marine vessels, and off-grid systems where electrical isolation between battery circuits is a technical or safety requirement.\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, preventing ground loops and protecting sensitive electronics from voltage spikes or faults on the source circuit.\u003c\/li\u003e\n  \u003cli\u003e48V input to 48V output at up to 8A continuous, delivering up to 380W of charging power.\u003c\/li\u003e\n  \u003cli\u003eBuilt-in Bluetooth via the VictronConnect app, allowing configuration, monitoring and firmware updates without additional hardware.\u003c\/li\u003e\n  \u003cli\u003eAdaptive charging algorithm with configurable charge profiles to suit different battery chemistries including lithium and lead-acid variants.\u003c\/li\u003e\n  \u003cli\u003eEngine detection input to prevent excessive discharge of the starter battery by only operating when the alternator is active.\u003c\/li\u003e\n  \u003cli\u003eRemote on\/off control via a dedicated terminal, enabling integration with vehicle management systems or external switches.\u003c\/li\u003e\n  \u003cli\u003eCompact, fully enclosed aluminium housing rated for demanding installation environments.\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 a high-frequency transformer to provide true galvanic isolation between the input and output circuits. In a 48V-to-48V application, this matters because the two battery banks may share a chassis ground or be connected to equipment with different earthing references. Without isolation, a direct DC-DC converter would create a common path between the two circuits, which can cause corrosion, interference and fault propagation. The transformer breaks that path entirely.\u003c\/p\u003e\n\n\u003cp\u003eConfiguration is handled through the VictronConnect app over Bluetooth. Installers can set the absorption voltage, float voltage, bulk current limit and tail current threshold to match the target battery chemistry. This makes the unit suitable for charging lithium iron phosphate batteries alongside conventional AGM or gel banks, provided the correct profile is applied. The engine detection input monitors the input voltage to determine whether the alternator is running, and the unit will not draw from the source battery below a configurable threshold, protecting the starter circuit.\u003c\/p\u003e\n\n\u003cp\u003eAt 380W continuous output, the 48\/48-8A is suited to applications where moderate charge current is needed between a primary 48V bank and a secondary 48V service or auxiliary bank. It is not a bulk charger for large battery systems but works well as a secondary charging source in dual-bank setups or as the primary DC charging path in smaller off-grid or mobile installations.\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  \u003cthead\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  \u003c\/thead\u003e\n  \u003ctbody\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;\"\u003eORI484838120\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eInput Voltage\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 Voltage\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;\"\u003eMaximum Output Current\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eMaximum Output Power\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e380W\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;\"\u003e8719076065609\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCharging a 48V auxiliary or service battery from a 48V starter or house bank in commercial vehicles and coaches.\u003c\/li\u003e\n  \u003cli\u003eMarine dual-bank systems where galvanic isolation is required to prevent corrosion between isolated battery circuits.\u003c\/li\u003e\n  \u003cli\u003eOff-grid cabins or mobile installations using a 48V primary bank to charge a separate 48V secondary bank.\u003c\/li\u003e\n  \u003cli\u003eTelecom and industrial equipment requiring an isolated 48V supply from an existing 48V bus.\u003c\/li\u003e\n  \u003cli\u003eRetrofit installations where two 48V systems must be electrically separated for safety or regulatory reasons.\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 48\/48-8A isolated DC-DC charger unit\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 48V DC systems.
