Product description
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 12-V batteries from a 48-V system. With an output current of up to 20 A and freely configurable output voltage via Bluetooth, the device is particularly flexible in its application – as a charge booster for service batteries, voltage converter, or constant power source.
Thanks to its adaptive 3-stage charging algorithm, the charge booster is perfectly suited for lead and lithium batteries. The galvanic isolation provides additional protection for the onboard electrical system – ideal for vehicles with Euro 5/Euro 6 engines or for long cable lengths (e.g. in boats or motorhomes).
