The Victron Energy Orion-Tr 24/12-10 (120W) is a non-isolated DC-DC converter designed to power compatible 12V-class equipment from a nominal 24V DC electrical system. It operates across an 18–35V DC input range and provides a regulated 12.5V DC output with 10A continuous output current. 

Designed for efficient and straightforward DC power conversion, the Orion-Tr uses synchronous rectification and achieves 97% efficiency for this exact model. Screw-terminal connections simplify installation, while IP43 protection is provided when the converter is installed with its screw terminals oriented downward.

Key Technology

• 24V-to-12V DC Conversion
  Converts power from a nominal 24V DC source to a regulated 12.5V DC output for compatible lower-voltage equipment.

• Wide Input Voltage Range
  Accepts 18–35V DC input, making the converter suitable for properly configured 24V battery-based and DC electrical systems.

• 10A Continuous Output
  Provides 10A continuous output current with a maximum specified output current of 12A. 

• 97% Efficiency
  Synchronous rectification provides highly efficient DC power conversion, with this exact Orion-Tr model specified at 97% efficiency.

• Non-Isolated Architecture
  Uses a non-isolated design with no galvanic isolation between input and output, making it suitable for applications where electrical isolation is not required.

• Low Off-Load Consumption
  Off-load current is specified at less than 45mA, helping limit converter consumption when the connected equipment is not drawing significant power.

• IP43 Protection
  Provides IP43 protection when installed in the orientation specified by Victron, with the screw terminals facing downward.

• Screw-Terminal Connections
  Uses screw terminals for DC wiring, allowing installation without specialized connection tools.

Best Uses

• 24V Battery Systems
  Ideal for operating compatible 12V equipment from a properly configured 24V battery bank.

• Vehicle Electrical Systems
  Suitable for compatible automotive and mobile installations that require a lower-voltage DC supply from a 24V electrical system.

• Marine DC Systems
  Useful for supplying compatible 12V electronics and accessories from an onboard 24V DC electrical system.

• Off-Grid Power Systems
  Provides DC voltage conversion for compatible auxiliary equipment within battery-based solar and standalone power systems.

• 12V Electronics & Accessories
  Suitable for compatible controls, communications equipment, electronics, lighting, and other loads designed for a 12V-class DC supply.

• Auxiliary DC Power
  A practical option when a 24V electrical system requires a dedicated lower-voltage supply without adding a separate 12V battery bank.
