DC-DC-converter Victron Energy Orion-Tr 48/48-2.5A 120 W — geïsoleerd 48 V naar 48,2 V

The Victron Energy Orion-Tr 48/48-2.5A is an isolated DC‑DC converter that delivers up to 120 W of regulated power, converting a nominal 48 V input into a stable 48.2 V output at a maximum current of 2.5 A. Designed for systems that require galvanic isolation between source and load, this converter maintains voltage stability under varying load conditions and is suitable for battery systems, telecommunication equipment, and onboard electronics in vehicles and boats where a precisely regulated 48.2 V supply is needed.

Advantages

The Orion-Tr provides galvanic isolation between input and output to prevent ground loops and improve system safety. Its built-in voltage regulation keeps output voltage within tight tolerances even when input voltage or load changes. Compact construction and robust protection features, including short‑circuit and thermal protection, support reliable continuous operation in demanding environments. The unit’s efficiency minimizes heat generation and reduces energy losses in DC power chains.

Key specifications

How to use

Install the converter in a dry, ventilated location with adequate clearance for heat dissipation. Connect the 48 V DC source to the input terminals respecting polarity and ensure a secure mechanical mounting to minimize vibration. Connect the load to the output terminals, confirming the 48.2 V requirement of downstream devices. Verify correct wiring and fuse protection in the input circuit before energising the unit. Monitor the unit during initial power‑up for proper output voltage and thermal behaviour.

Recommendations

For reliable operation, use appropriately rated cabling and fuses on the input side, ensure the ambient temperature remains within the converter’s specified range, and provide adequate ventilation or mounting space to reduce thermal stress. Avoid exposing the module to continuous overloads and periodically inspect connections for corrosion or loosening in mobile or marine environments.
