Product Details

The Victron Orion‑Tr 48/12‑30A (360 W) Isolated DC‑DC Converter (SKU ORI481240110) is a high-quality power conversion solution tailored for mobile, marine and industrial 48 V systems needing a 12 V supply. With a wide 40-70 V input voltage range and an adjustable 10-15 V output (nominal 12.2 V) it offers excellent flexibility for auxiliary and service battery banks.

Rated at 30 A continuous at 40 °C (≈360 W) and capable of delivering up to 430 W at 25 °C, it supports robust loads while operating reliably in demanding conditions. Galvanic isolation of 200 V dc between input, output and chassis ensures safe operation in systems where grounding and isolation matter. Screw-type terminals allow tool-free installation and the remote on/off terminal eliminates the need for a high-current switch in the input wiring.

Built for real-world installations, the converter offers IP43 protection (when correctly mounted with terminals downwards) and is short-circuit proof, with unlimited parallel capability to scale output current if needed.

In a compact package, approximately 130 × 186 × 70 mm and weighing 1.6 kg, it fits neatly into confined installation spaces onboard boats, in vehicles or within industrial enclosures.

Whether you're powering lighting, control electronics, service batteries or auxiliary circuits from a 48 V bank, this converter delivers dependable 12 V power with advanced protection, adjustability and scalability.
