Detailed description
Detailed description
Designed to provide stable 12 V DC power from a 12 V source, the Victron Energy Orion Tr 12/12-9A (ORI121210110) is a power conditioning solution. This isolated DC-DC converter delivers continuous power of 110 W at 25 °C and an output current of 9 A at a nominal voltage of 12.2 V. Its input voltage range of 8 to 17 V ensures reliable operation even with voltage variations in the main power system.
Technical Features and Versatility
The Orion Tr 12/12-9A features an adjustable output voltage between 10 and 15 V, allowing it to be used as a battery charger for dedicated 12 V batteries. The remote on/off function simplifies integration into complex systems, eliminating the need for a high-current switch. The device is protected against short circuits and includes a non-replaceable internal fuse for safety. Its ability to be connected in parallel allows increasing the total output current for applications requiring more power. Compared to higher-power Orion Tr models (e.g., 220 W or 280 W versions), the 12/12-9A is suited to installations with lower power consumption or where paralleling multiple units is preferred for increased modularity.
Integration and Compliance
With compact dimensions of 100 x 113 x 47 mm and a weight of 0.42 kg, this converter is installed via screw terminals, simplifying wiring. The 200 V DC galvanic isolation between input, output, and case provides essential electrical separation for protecting sensitive equipment and preventing ground loops. The Orion Tr 12/12-9A complies with EN 60950, EN 61000-6-3, EN 55014-1, EN 61000-6-2, EN 61000-6-1, EN 55014-2, and ECE R10-5 standards, attesting to its reliability and electromagnetic compatibility. Its operating temperature range is from -20 to +55 °C, with a 3 % current reduction per °C above 40 °C. The protection rating is IP20, but can reach IP43 when installed with screw terminals facing downward.
