60-day hassle-free returns
The Orion-Tr 24/12 non-isolated DC-DC converter is a compact, highly efficient way to run 12 V electronics and accessories from a 24 V battery system. It takes the 24 V supply and delivers a tightly regulated 12 V output, so navigation gear, lighting, pumps, and other 12 V loads get steady voltage even as the source battery rises and falls with charging. It's a popular, no-fuss building block on boats, RVs, and commercial vehicles that run a 24 V house system but still have 12 V equipment.
This is a fixed-output voltage converter, not a battery charger. Its output is preset (about 12.5–12.7 V) to power 12 V loads; it has no charge algorithm. To charge a 12 V battery from a 24 V system, use a DC-DC charger instead.
Very high efficiency, very little heat
Thanks to synchronous rectification, full-load efficiency reaches up to 97% (95% on the smallest model). That means minimal wasted energy and very little heat — well suited to continuous operation in the confined spaces typical of marine and mobile installs.
Non-isolated: compact and simple for shared-ground systems
This converter shares a common negative between input and output, which keeps it small, light, and efficient — ideal when your 24 V and 12 V circuits already use the same ground reference. (If you need the input and output grounds electrically separated, choose an isolated Orion-Tr converter instead.)
Simple installation
Connections are screw terminals (no special tools), and each unit is protected against short circuit and over-temperature. Rated IP43 when installed with the terminals facing downward; operating range −20 to +55 °C.
Choosing your model
All four models step 24 V (input 18–35 V) down to a regulated 12 V. Pick by continuous output current: 5 A (60 W), 10 A (120 W), 15 A (180 W), or 20 A (240 W). The smallest is a tiny potted module; the 10/15/20 A units share a slightly larger case. Exact current, efficiency, and dimensions are on each variant below.
