The Orion-Tr Smart 12/48-8A is an isolated DC-DC charger. It accepts an input of 8 to 17 V and delivers 48.2 V at 8 A continuous, which is 360 W at 40°C. Isolation lets the input and output keep separate chassis grounds, and Bluetooth allows it to be monitored and configured. Maximum efficiency is 89 %. Output derates by 3 % per degree above 40°C.
Our take
The 3 % output derating per degree above 40°C is the number to watch on this 48.2 V, 8 A charger, since it holds 360 W only up to 40°C and heat trims the output beyond that. Isolation keeps the input and output chassis grounds apart.
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.
