Detailed description
Detailed description
Designed for DC voltage conversion, the Victron Energy Orion-Tr 12/48-8A (380W) is an isolated DC-DC converter capable of transforming a 12 V input voltage into an adjustable 48 V output. This model delivers a continuous power output of 380 W at 40 °C, with an output current of 8 A, and can reach 430 W at 25 °C. Its efficiency is 89 %.
Design and Technical Performance
The Orion-Tr 12/48-8A (380W) converter stands out for its isolated design, providing 200 VDC galvanic isolation between the input, output, and case, ensuring enhanced safety in marine or industrial installations. It operates within an input voltage range of 10 to 17 V and offers a nominal output voltage of 48.2 V, adjustable from 40 to 60 V to suit various applications. The operating temperature range is from -20 to +55 °C, with power derating above 40 °C.
Integration and Advanced Features
This converter features a remote on/off terminal, eliminating the need for a high-current switch on the input wiring and allowing control via a low-power switch or engine start contact. All Orion-Tr series models are protected against short circuits and can be connected in parallel in unlimited numbers to increase total output current. IP43 protection is ensured when screw terminals are oriented downward. Note that this model is not designed for battery charging; for this function, Orion-Tr Smart models are recommended. Its dimensions are 130 x 186 x 80 mm with a weight of 1.8 kg, and it uses screw terminals for DC connections up to 16 mm².
