The Victron Orion-Tr 48/12-9A is an isolated DC-DC converter that takes a 32 to 70 V input and gives a 10 to 15 V output range. It delivers 9 A continuous, with a 12.5 A maximum, which is 110 W at 25°C and 85 W at 40°C. Isolation is rated 200 VDC. This model has no Bluetooth.

Our take

The 110 W rating is for 25°C and drops to 85 W at 40°C, so the 9 A continuous figure assumes a cool spot. With 200 VDC isolation between a 32 to 70 V input and a 10 to 15 V output, it keeps the two sides separate.

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.
