Orion-Tr 48 / 24-12A (280W)

The Orion-Tr 48/24-12A DC-DC converter from Victron Energy is a modern solution designed for the most demanding users who need a reliable device to convert DC voltage from 48 V to 24 V. Thanks to its advanced design, this device is characterized not only by high energy efficiency but also exceptional durability, making it an ideal choice for applications in harsh conditions, such as solar installations, camper systems, or industrial power systems. Orion-Tr offers a high efficiency of 89%, which guarantees minimal energy losses during conversion, which translates into lower operating costs and a longer service life of the entire installation.
The device is designed for a wide input voltage range of 32V to 70V, making it an extremely flexible solution for various power systems. Additionally, the converter features an automatic restart function at 30V, which increases its reliability and eliminates the risk of system downtime. The robust metal housing is resistant to mechanical damage and harsh weather conditions, making the Orion-Tr converter safe for use in a variety of environments – both indoors and outdoors. This design, combined with short circuit resistance and the ability to operate in high humidity (up to 95% non-condensing), ensures the device can operate smoothly even in the most demanding applications.

Versatile Applications and Easy Installation

The Victron Energy Orion-Tr is designed to meet the requirements of a wide range of industries and sectors. Its versatile applications include solar systems, recreational vehicle installations, yachts, and other mobile power sources. With an output voltage regulation range of 20V to 30V, this converter is ideal for powering sensitive electronic devices that require stable and precise voltage to minimize the risk of damage. An additional advantage is the ease of installation - screw terminals that do not require special tools significantly reduce installation time, and IP43 protection ensures safety even when mounted outdoors, provided the terminals are facing downwards.
The Orion-Tr converter also supports parallel connection, allowing for increased output current, which is particularly useful in systems with high energy demands. Whether you're using this converter in a residential photovoltaic system or in more advanced industrial systems, this device guarantees stable operation, low power consumption, and longevity. Furthermore, in emergency situations, the Orion-Tr converter provides a maximum output current of 15A for 10 seconds, ideal for momentary, increased system loads.
