Reliable DC-DC Power Conversion for 12V, 24V and 48V Systems

Integrate stable, efficient DC power into your vehicle or off-grid electrical system with the Victron Orion-Tr 24/12-15A Non-Isolated DC-DC converter. Designed for professional installations where voltage stability matters, it converts 24V (18-35V input range) to 12.5V to help protect sensitive loads and support consistent operation of devices such as communications gear, LED lighting, fridges, navigation electronics and other DC equipment.

In real-world setups—especially in caravans, 4WDs, marine systems and remote power applications—DC supply can be unpredictable. Alternator output varies with engine speed, cable runs introduce voltage drop, and mixed-voltage battery banks can create compatibility issues. This unit helps reduce those risks by delivering a regulated output that better matches the needs of your downstream devices and distribution.

High Efficiency Where It Counts

Victron’s design approach prioritises conversion efficiency to minimise wasted energy and heat—an important advantage in enclosed electrical bays and compact builds. With a 97% efficiency rating, this unit translates to less strain on source batteries, improved runtime, and more headroom for additional loads. The design supports stable operation under changing input conditions, helping your system behave more predictably when the alternator, batteries or solar charging state changes.

Installation-Ready for Mobile and Harsh Environments

Built for practical field installation, the unit features robust connections and a durable enclosure suited to mobile power systems. For applications where ventilation, dust and splash exposure are considerations, the housing and terminal layout are designed to support a tidy, serviceable install. Use it as part of a broader Victron ecosystem or as a focused solution to solve a specific voltage conversion requirement such as running 12V electronics from a 24V battery system.

Ideal Use Cases Across Australia

From touring rigs to commercial fit-outs, DC-DC conversion is often the missing link between a source supply and reliable end-use power. This unit is a strong choice for:

• Caravan and RV electrics needing stable DC rails for accessories
• 4WD touring where voltage drop and load spikes are common
• Marine systems requiring dependable DC power distribution
• Off-grid and industrial systems with mixed-voltage loads

Key Features

• Efficient DC-DC conversion to support longer runtime and lower heat build-up
• Regulated output designed to improve stability for sensitive DC loads
• Rugged construction suited to mobile, marine and off-grid environments
• Installer-friendly terminals for secure cabling and straightforward servicing
• Designed to integrate cleanly into professional power systems

Optimised for Your System

This unit is matched for 24V (18-35V range) input, providing a regulated 12.5V output with a 15A continuous current capacity. If you’re planning a new build or upgrading an existing setup, this converter helps create a more predictable electrical system—reducing nuisance resets, improving device performance, and supporting cleaner power distribution.

Equip your build with the Victron Orion-Tr 24/12-15A Non-Isolated DC-DC converter and power your 12V distribution from a 24V supply with stable, efficient DC conversion suited to Australian touring and off-grid conditions.
