Orion-Tr 24/48-8,5A (400W) Isolated DC-DC converter

The Victron Energy Orion-Tr 24/48-8.5A (400W) is an isolated DC-DC converter designed to power 48V DC equipment from a 24V DC electrical system. It provides a regulated 48.2V nominal output with galvanic isolation between the input, output, and enclosure.

Its adjustable output, remote on/off connection, short-circuit protection, and ability to operate multiple units in parallel make it suitable for professional vehicle, marine, industrial, telecommunications, and off-grid electrical systems.

Key Features:

• 24V-to-48V DC conversion: Converts power from a nominal 24V DC source into a regulated 48.2V DC output.
• 400W continuous output at 104°F: Delivers 8.5A continuously at its nominal output voltage.
• Up to 480W at 77°F: Provides additional continuous output capacity at lower ambient temperatures.
• Adjustable output voltage: The output can be adjusted from 40V to 60V DC to meet the requirements of compatible DC loads.
• Galvanic isolation: Provides 200V DC isolation between the input, output, and enclosure, allowing the input and output sides to use separate electrical grounds.
• Remote on/off connection: Allows the converter to be controlled using a low-power switch or a compatible engine run/stop signal without installing a high-current switch in the input wiring.
• Parallel operation: Multiple converters can be connected in parallel to increase the available output current.
• Short-circuit protected: Designed to protect the converter during an output short circuit.
• High-temperature protection: Automatically reduces output current when the ambient temperature becomes too high.
• Integrated input fuse: The 24V input model includes a non-replaceable internal input fuse.
• Screw-terminal connections: Supports straightforward installation without specialized terminal tools.
• IP43 protection: Achieved when the unit is installed with its screw terminals facing downward.

The Orion-Tr 24/48-8.5A is ideal for supplying regulated power to compatible 48V DC electronics and equipment from a 24V vehicle, vessel, telecommunications, industrial, or off-grid electrical system.

Important: This product is a DC-DC power converter and is not intended to charge a battery. For battery-charging applications, use an appropriately selected Victron Orion-Tr Smart or Orion XS DC-DC battery charger.
