The Orion-Tr 24/24-12A is an isolated DC-DC converter from Victron Energy. It takes a 24 V supply anywhere in a 16 to 35 V input range and delivers 24 V, with galvanic isolation between the two sides. Continuous output is 12 A, which works out to 320 W at 25°C and 280 W at 40°C. The blue case is rated IP43 and the DC side uses screw terminals, with a separate two-pole remote on/off terminal.

Our take

The remote on/off terminal means the input wiring needs no heavy-duty switch, since a small switch or the engine run/stop signal can control the unit. The IP43 rating holds only with the screw terminals pointing down, so mount it with that in mind.

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.
