Victron Energy Orion-TR 24/12-20A Isolated DC-DC Converter for Vehicle and Marine Applications

Orion-TR 24/12-20A (240W) Isolated DC-DC Converter

Isolated Model - separate in and out (-) leads

Remote On/Off Terminal

The remote on/off terminal eliminates the need for a high current switch in the input wiring. The remote on/off can be operated with a low power switch or for example the engine run/stop switch.

All Models Are Short Circuit Proof and Can Be Paralleled to Increase Output Current

An unlimited number of units can be connected in parallel.

High Temperature Protected

The output current will reduce at high ambient temperatures.

IP43 Protection

When installed with the screw terminals oriented downward.

Screw Terminals

No special tools are needed for installation.

Input Fuse (not replaceable)

On 12 V and 24 V input models only.

Adjustable Output Voltage

Not intended for battery charging (consider using an Orion-Tr Smart for battery charging).

The Victron Energy Orion-TR 24/12-20A DC-DC converter provides reliable 12-volt power conversion from a 24-volt system, ideal for vehicle, marine, or off-grid applications. This isolated model features separate input and output grounds, ensuring electrical safety and reducing interference. Its remote on/off terminal allows convenient operation without high current switches, making it suitable for integration with engine control systems or remote panels. The converter is short circuit proof and can be paralleled with an unlimited number of units, enabling increased output current for demanding power needs.
Constructed with durability and safety in mind, the Orion-TR includes high temperature protection that reduces output current at elevated ambient temperatures to prevent overheating. Its IP43-rated enclosure ensures protection against dust and water spray when installed with screw terminals oriented downward. The device’s screw terminals facilitate straightforward installation without special tools, and the input fuse (standard on 12V and 24V models) adds an extra layer of protection, although it is not replaceable.
The adjustable output voltage feature allows fine-tuning within a range of 10 to 15 volts, although it is not intended for battery charging applications. With an input voltage range of 16 to 35 volts, the converter maintains stable output with a nominal 12.2 volts and a tolerance of ±0.2 volts. It delivers a continuous 20 amps at 40°C, with a peak of 25 amps for short durations, supporting up to 300 watts of power at optimal temperatures. Its high efficiency of 88% ensures minimal energy loss, while a low noise output of 2 mV RMS maintains signal integrity in sensitive environments.
This converter operates reliably between -20°C and +55°C, with a derating factor above 40°C. It maintains maximum humidity levels of 95% non-condensing. The galvanic isolation of 200 VDC between input, output, and case enhances safety and reduces ground loop issues. Designed with industry standards compliance, including EN 60950 safety and EN 61000 series immunity standards, the Orion-TR is suitable for automotive and industrial applications, meeting ECE R10-5 standards for electromagnetic compatibility.
