Description
The Victron Orion-Tr Smart 48/12-20A is a professional‐grade, galvanically-isolated DC-DC charger that converts any 32–70 V DC source (e.g. a 48 V alternator or battery bank) into a fully regulated 12 V output at up to 20 A (240 W). Featuring Victron’s adaptive three-stage charging algorithm (Bulk, Absorption, Float), Bluetooth-programmable settings via the VictronConnect app, and comprehensive protection (short-circuit, over-voltage, reverse-polarity and temperature derating), it’s ideal for off-grid systems, marine installations, commercial vehicles and industrial applications where safe, reliable 12 V charging is critical.
