Detailed description
Detailed description
The Victron Energy Orion-Tr 24/48-2.5A isolated DC-DC converter is a robust and reliable solution for marine and embedded electrical systems requiring stable conversion from 24V DC to 48V DC. Part of Victron Energy's Orion-Tr range, this 120W model features 200V DC galvanic isolation between input, output, and case, essential for preventing ground loops and ensuring the safety of sensitive equipment. With a continuous output current of 2.5A at 48.2V, it is designed to power specific loads requiring this voltage.
Performance and Flexibility of the Orion-Tr
Operating within an input voltage range of 16-35V, this converter provides a nominal output voltage of 48.2V, manually adjustable via a potentiometer over a range of 40-60V. This flexibility allows precise adaptation to system requirements, though it is not specifically designed for battery charging like the Orion-Tr Smart models. The Orion-Tr 24/48-2.5A maintains an efficiency of 88%, minimizing energy losses. It is protected against short circuits and includes high-temperature protection, automatically reducing the output current above 40°C to ensure the device's longevity.
Integration and Reliability
The Orion-Tr 24/48-2.5A converter is easy to integrate thanks to screw terminals, eliminating the need for specialized tools. A remote on/off function allows control of the device via a low-power switch or engine contact, simplifying system management without requiring high-current switches on the input wiring. Its design also allows an unlimited number of units to be connected in parallel to increase output current, offering unique scalability. With IP43 protection, it is suitable for environments where water spray may occur, provided it is installed with terminals facing downward. This converter is positioned as a compact and economical alternative to more powerful solutions or dedicated battery chargers, such as higher-power Victron Orion-Tr Smart converters or dedicated battery chargers.
