Victron Energy Orion-Tr 24/12 10A DC-DC Converter (120W, non-isolated) converts 24V power to a regulated 12V/10A output for running 12V loads and accessories in 24V vehicles and dual-battery systems. Best fit: truck, boat, and off-grid builders who need reliable 12V accessories on a 24V platform. Current price: $16.58 — 50% off $33.15.

Can It Charge a 12V Battery?
The Orion-Tr 24/12 is a constant-voltage power converter, not a multi-stage charger. It can maintain or trickle-charge a small 12V battery and reliably power 12V loads, but for charging larger or lithium 12V banks from 24V, choose the Orion-Tr Smart isolated DC-DC charger with its three-stage algorithm.
Wiring & Fuse Sizing
Use the screw terminals for input and output. Typical wiring: 24V source → inline fuse (15–20A recommended on the input) → Orion-Tr input; output → fused 12V load distribution. Observe polarity and keep runs appropriately gauged for 10A continuous output.
