The Victron Orion-Tr 48/48-8A is an isolated DC-DC converter that puts out 48.2 V from an input of 32 to 70 V. It is rated for 8 A of continuous output, with 200 VDC of isolation between the input and output sides. Peak efficiency is 89 percent. The IP43 rating applies when the screw terminals face downward, and a remote on/off terminal lets the unit be switched from a distance.
Our take
The 200 VDC isolation rating means the 48.2 V output is galvanically separate from the input side, and the 8 A continuous rating caps what it can feed. Its IP43 rating only holds with the screw terminals pointing down, so mounting orientation matters.
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.
