Detailed description
Detailed description
The VICTRON ENERGY Orion 24/24-12A (280W) isolated DC-DC converter (model ORI242428110) is a robust power conversion solution designed to provide a stable 24 V output voltage from a 24 V input source. Part of the Orion-Tr isolated range (220–280 W), it serves as an essential component for marine and embedded systems requiring reliable and secure power supply. Unlike the Orion-Tr Smart versions, this model is optimized for voltage conversion rather than battery charging, though it can provide a stable 24 V supply to consumers.
Galvanic Isolation and System Safety
This converter features 200 V DC galvanic isolation between input, output, and case—a critical feature for preventing ground loops and reducing electromagnetic interference in sensitive marine environments. This isolation enhances protection for connected equipment and improves the integrity of the electrical system. The input voltage range is 16–35 V, and the output voltage is adjustable from 18 to 30 V, allowing precise adaptation to the specific requirements of 24 V devices.
Performance and Integration Flexibility
With a continuous output current of 12 A and a maximum power output of 280 W (320 W at 25 °C), the Orion 24/24-12A efficiently handles significant loads. Its 89 % efficiency minimizes energy losses. The remote on/off function simplifies integration into complex energy management systems, enabling control via a low-power switch or directly from the engine’s start/stop system. For applications requiring higher power, an unlimited number of units can be connected in parallel, offering scalable performance without compromise. The device is also protected against short circuits and overheating, automatically reducing the output current at high ambient temperatures to ensure longevity.
Robust Design and Ease of Installation
Designed for demanding environments, this converter offers IP43 protection when installed with screw terminals facing downward, shielding it from water spray and dust. The screw terminals facilitate installation without requiring specialized tools, and its operating temperature range of -20 to +55 °C attests to its robustness. Its compact dimensions of 130 x 186 x 70 mm and weight of 1.3 kg make it easy to integrate into various technical compartments.
