The Victron Energy Orion-Tr is an isolated DC-to-DC converter that takes 12 V in and puts out a regulated 12 V at up to 9 A, about 110 W. Isolation between input and output keeps the two battery circuits electrically separate, which suits dual-battery setups in vehicles, boats and campers. It is IP43 protected, so it tolerates splashes and dust rather than full immersion. Against plain non-isolated chargers it costs more complexity but avoids ground loops and lets you charge a second battery bank with a stable output voltage.
