Victron Orion-TR DC-DC Converter - 12 VDC to 12 VDC - 18AMP Isolated

The Victron Orion-TR DC-DC Converter—12 VDC to 12 VDC, 18AMP Isolated—is engineered for modern vehicle electrical systems that demand intelligent power distribution without ground loop interference. This isolated converter is purpose-built for dual-battery setups, auxiliary power systems, and complex automotive applications where traditional direct connections introduce noise, voltage regulation issues, or safety risks. Whether upgrading a mobile workshop, expedition vehicle, camper, or specialized work truck, this unit provides silent, efficient voltage stabilization between battery sources or charging systems.

The isolated architecture keeps the input and output negative leads electrically separate, eliminating parasitic ground loops that degrade alternator performance and create RF interference in modern vehicle electronics. Rated for 18 amps of continuous output, the Orion-TR handles high-draw auxiliary loads—winches, compressors, inverters, or fridge systems—while regulating voltage within tight tolerances to protect sensitive electronics and extend battery life. The compact form factor (5 × 4 × 8 inches, 2.8 lbs) mounts easily under seats, behind panels, or in engine bays, and the remote on-off function eliminates the need for high-current switching in primary wiring, reducing installation complexity and fire risk in high-amperage circuits.

Mechanics and fabricators favor this converter for vehicles using split-battery systems—especially overlanding builds, emergency response vehicles, and heavy-duty trucks where a primary alternator charges both the engine battery and auxiliary lithium or AGM banks. It excels in RV retrofits, marine auxiliary setups, and any rig where ground-return paths are compromised by aftermarket wiring. Installation requires clean 12V input from the vehicle's main battery or secondary charging source, routed through appropriate fusing; output connects directly to auxiliary circuits or loads requiring isolated, regulated 12V power. Compatible with both lead-acid and lithium battery chemistries, the Orion-TR operates silently—critical for noise-sensitive applications like mobile offices, stealth camping, or scientific fieldwork.
