The Orion-Tr 24/12-20 steps a 24 V system down to 12 V. It accepts an input from 18 to 35 V and puts out 12.5 V, with 20 A continuous and 25 A as the maximum output current. It uses synchronous rectification, and full load efficiency exceeds 95 percent. The enclosure is rated IP43. Output derates by 3 percent for each degree C above 40 C, which sets how much current is left in a warm space.
Our take
Output derates 3 percent per degree C above 40 C, so the 20 A continuous rating shrinks as the compartment warms. Give this converter some airflow rather than burying it behind other gear.
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.
