The Victron Orion-Tr 48/24-12A is an isolated DC-DC converter that steps a 48 V supply down to 24 V. It accepts 32 to 70 V in and is rated for 12 A continuous output, which is 280 W up to 40°C. The output is galvanically isolated, rated 200 VDC, and units can be paralleled. The IP43 rating applies when the screw terminals face downward.

Our take

The 200 VDC galvanic isolation means the 24 V side is not electrically tied to the 48 V input bank. The 12 A continuous rating is the ceiling to size your 24 V loads against, and units can be paralleled if you need more.

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.
