Isolated DC-DC Converters

Victron Orion-Tr Isolated DC-DC Converters for 12V, 24V and 48V Systems

An isolated DC-DC converter changes one DC voltage to another and keeps the input and output circuits electrically separate. This collection covers the Victron Orion-Tr isolated range. It includes step-down (buck) models such as 24V to 12V and 48V to 12V, step-up (boost) models such as 12V to 24V and 12V to 48V, and same-voltage regulators for 12V, 24V and 48V systems. Each converter has an adjustable output voltage potentiometer, so you can set the output to suit the connected load.

Why Choose an Isolated Converter?

Galvanic isolation creates a barrier between the input and output. This helps prevent unwanted current paths between systems, reduces electrical noise reaching sensitive equipment, and allows two separate DC systems to run from a common power source. If your application does not need isolation and you want a more compact option, compare the non-isolated DC-DC converters. For a detailed side-by-side explanation, read our guide to isolated vs non-isolated converters and DC-DC chargers.

Choosing the Right Orion-Tr Model

Start with your battery bank voltage and the voltage your appliance needs. Then choose an output current rating with headroom above the continuous load. The available Orion-Tr isolated configurations are:

• 12V to 12V: 9A, 18A and 30A models for stabilising supply to sensitive 12V electronics
• 24V to 12V: 9A, 20A and 30A models for running 12V accessories from a 24V system
• 48V to 12V: 9A, 20A and 30A models for 12V loads in 48V battery installations
• 12V to 24V: 5A, 10A and 15A step-up models for 24V equipment on a 12V system
• 24V to 24V: 5A, 12A and 17A models for regulated, isolated 24V supply
• 48V to 24V: 5A, 12A and 16A models for 24V loads in 48V systems
• 12V to 48V: 8A step-up model for 48V equipment on a 12V system
• 24V to 48V: 2.5A, 6A and 8.5A step-up models
• 48V to 48V: 2.5A, 6A and 8A models for isolated 48V regulation

These Orion-Tr units are voltage converters that supply a regulated output to loads. If you need multi-stage battery charging, compare the options across the full DC-DC converters range before you buy.

Common Use Cases

Isolated converters are a practical choice wherever separate electrical systems or sensitive equipment need clean, regulated power:

Trucks and buses: Run 12V radios, fridges, USB outlets and navigation units from a 24V vehicle electrical system.

Marine and boats: Isolation between systems helps reduce the risk of stray current paths, and a stable 12V supply suits electronics, instruments and communication gear.

Off-grid, tiny home and industrial: Power standard 12V or 24V loads directly from a 48V battery bank, or boost a 12V system to drive 24V or 48V equipment.

Caravan, RV and 4WD: Feed voltage-sensitive devices with a steady output when battery voltage rises and falls under load or charging.

Choose your input and output voltages, select a current rating that covers your continuous load with margin, and order your Victron Orion-Tr isolated converter today for clean, dependable power conversion across your system.
