The Victron Orion-Tr 48/12-30A (360W) Isolated DC-DC Converter, ORI481240110, steps a 48V DC input down to a regulated 12V DC output rated at up to 30A. Full galvanic isolation separates the two circuits, so it suits vehicles, vessels, off-grid systems and industrial equipment where two DC systems share a chassis ground.

Key features of this Victron DC DC converter

• Isolation, galvanic isolation between input and output removes ground loop issues.
• Conversion, 48V input to a 12V output at up to 30A, delivering up to 360W.
• Housing, compact, enclosed aluminium housing suited to fixed installation in confined spaces.
• Output adjustment, output voltage can be tuned to suit a specific load or charging requirement.
• Parallel operation, additional Orion-Tr units can be wired in parallel to raise output current beyond 30A.
• Weight, 1.8kg.

Applications

Typical uses include powering 12V auxiliary loads from a 48V off-grid battery bank, charging a 12V service battery from a 48V house bank on a boat or motorhome, supplying isolated 12V control circuits in industrial or telecoms DC systems, and keeping 48V and 12V circuits electrically separate in mixed-voltage vehicle conversions.

Installation notes

Fit this unit with input wiring correctly fused at the source, and mount it on a flat surface with room for airflow. Set the output voltage before connecting any load. Where the converter forms part of a larger battery or solar system, check compatibility with the rest of the equipment before commissioning. Installation should be carried out by a qualified electrician or an experienced systems integrator familiar with DC power systems.
