The Victron Energy Orion-Tr 24/48-8.5 (400W) — is an isolated, regulated DC-DC converter that provides a reliable 48 V power supply to equipment from a 24 V source. Thanks to its built-in galvanic isolation (200 VDC), the device protects sensitive electronics, ensures electrical safety, and helps avoid issues with “ground loops” or electrical interference in vehicles, boats, and telecom systems.
Key advantages of the Orion-Tr 24/48-8.5 converter
- Power: 400 W, output current 8.5 A
- Stabilized output voltage: 48.2 V (adjustable from 40 to 60 V)
- Galvanic isolation: 200 V DC — complete isolation between input, output, and housing
- Efficiency up to 89%, low standby current (<120 mA)
- Capable of parallel operation — power scaling
- Remote on/off via signal or toggle switch
- IP43 when mounted with terminals facing down — protection against dust and splashes
- Compliant with ECE R10-5 — approved for use in vehicles
Technical features of the Orion-Tr DC-DC converter
Galvanic isolation — electrical safety first and foremost
The isolated converter guarantees:
- protection against parasitic currents
- no common “ground” between the source and the load
- protection of sensitive devices (radio, telecom, PLC)
Stable 48.2 V voltage with adjustment
- Output voltage regulation within 40–60 VDC
- Output stabilization with input voltage fluctuations of 16–35 V
- Ideal for powering GPS, telecom devices, and cameras
Scalability
- An unlimited number of Orion-Tr 24/48-8.5 units can be connected in parallel
- Get 17 A, 25.5 A, 34 A, and more by adding units
Converter application scenarios
- Cars and campers — stable power supply for sensitive 48 V devices
- Marine systems — navigation, lighting, communications
- Service vans and mobile offices — stable power
- Telecom and security — routers, controllers, cameras
- Automation systems, IT equipment — uninterrupted power supply
Communication interfaces
- Remote ON/OFF – Remote activation via BMS, engine, or button
- Adjustability – Trimmers for precise output voltage adjustment
