## Long description

The Victron Energy Orion-Tr 48/12-20A 240W Isolated DC-DC Converter is a high-performance power management solution engineered to convert a 48V DC input into a reliable 12V DC output. This professional-grade device is specifically designed for demanding environments where stable voltage is critical for the operation of sensitive electronic equipment. By utilizing advanced isolation technology, the converter effectively prevents ground loops and protects connected devices from potential electrical interference or voltage spikes, ensuring long-term durability and consistent performance in automotive, marine, and industrial applications.
Advantages
The primary benefit of this isolated DC-DC converter lies in its robust electrical isolation, which provides a significant layer of safety for sensitive downstream electronics by decoupling the input and output circuits. Its high efficiency ensures minimal energy loss during the conversion process, while the compact and durable housing allows for installation in various space-constrained environments. Furthermore, the unit is built to withstand the rigors of mobile and industrial use, offering stable power delivery even under fluctuating input conditions, which is essential for maintaining the integrity of communication systems, navigation equipment, and other critical 12V loads.
Suitable for
Marine electrical systems requiring stable 12V power from a 48V battery bank
Automotive applications for powering 12V accessories in 48V vehicle architectures
Industrial control systems and automation equipment
Telecommunications infrastructure requiring isolated power supplies
When it may not be suitable
This converter is not intended for applications requiring an output voltage other than 12V DC or for systems where the total power demand exceeds the 240W rating. It is also not suitable for AC power requirements, as it is strictly a DC-to-DC device.
Key specifications
Input voltage range: 48V DC
Output voltage: 12V DC
Output current: 20A
Power rating: 240W
Isolation: Fully isolated design
How to use
Installation should be performed by a qualified technician to ensure all safety standards are met. The converter must be connected to a 48V DC power source on the input side, ensuring correct polarity is observed. The 12V output terminals should be connected to the load, keeping cable lengths as short as possible to minimize voltage drop. Proper ventilation must be provided around the unit to allow for heat dissipation during operation. It is recommended to install appropriate fuses on both the input and output circuits to protect against short circuits or overcurrent conditions.
What to consider before purchase
Verify that your input voltage source is consistently within the 48V range
Ensure the total power consumption of your 12V devices does not exceed 240W
Check that the installation environment allows for adequate airflow
Confirm that the wiring gauge used is sufficient for a 20A continuous current
Usage recommendations
For optimal performance and longevity, mount the converter in a vertical position to facilitate natural convection cooling. Avoid placing the unit near heat sources or in areas with excessive moisture or dust. Regularly inspect all electrical connections to ensure they remain tight and free from corrosion.
