The Victron Orion-Tr 48/12-20A is an isolated DC-DC converter that steps a 48 V supply down to 12 V. Input range is 32 to 70 V, and it is rated for 20 A continuous output, or 240 W up to 40°C, with a 25 A maximum. The output is galvanically isolated, rated 200 VDC, and the unit shuts down when its input falls to 28 V.
Our take
The converter shuts down when its input falls to 28 V, which sets the lowest 48 V bank level it will work from. Its 20 A continuous rating sets the 12 V load it can carry, while the 200 VDC isolation keeps the output separate from the 48 V side.
From our buying guide
Each maker sets its own alternator rules. Battle Born calls a DC-to-DC charger a simple and safe way to use alternator charging.
Check before you buy:
- It can follow your battery's profile, since not every charger can follow a lithium maker's.
- Battle Born warns that a BMS shutdown leaves the vessel without power, and that one during alternator charging can severely damage the alternator.
