Victron Orion-Tr Smart 48/12-20A Isolated DC-DC charger

Victron Orion-Tr Smart 48/12-20A (Isolated) – Intelligent, isolated DC-DC charger for demanding applications

The Victron Orion-Tr Smart 48/12-20A is a powerful, galvanically isolated DC-DC charger ideal for charging 12V batteries from a 48V system . With up to 20A output current and freely configurable output voltage via Bluetooth, the device is particularly versatile – as a charging booster for service batteries, a voltage converter, or a constant current source.

Thanks to its adaptive 3-stage charging algorithm, the charging booster is perfectly suited for lead and lithium batteries . Galvanic isolation provides additional protection for the on-board electrical system – ideal for vehicles with Euro 5/Euro 6 engines or for long cable runs (e.g., in boats or mobile homes).
