The Victron Energy Orion-Tr 24/12-20 (240W) 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 20A continuous output current.

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

Key Technology

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

• Wide Input Voltage Range
  Operates across an 18–35V DC input range, providing flexibility for properly configured 24V battery-based and DC electrical systems.

• 20A Continuous Output
  Provides 20A continuous output current with a maximum specified output current of 25A.

• 97% Conversion Efficiency
  Uses synchronous rectification to reduce power-conversion losses, with the Orion-Tr 24/12-20 specified at 97% efficiency. 

• Non-Isolated Architecture
  Uses a non-isolated electrical design with no galvanic isolation between the input and output circuits.

• Low Off-Load Current
  Off-load current is specified at less than 35mA, helping limit converter consumption when connected equipment is not drawing significant power.

• IP43 Protection
  Provides IP43 protection when installed according to Victron's specified orientation with the screw terminals facing downward.

• Screw-Terminal Connections
  Uses screw terminals for DC wiring, providing straightforward electrical connections without requiring specialized installation tools.

Best Uses

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

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

• Marine DC Systems
  Useful for operating compatible 12V electronics and auxiliary equipment from an onboard 24V DC electrical system.

• Off-Grid Power Systems
  Provides DC voltage conversion for compatible auxiliary loads in battery-based solar and standalone electrical systems.

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

• Higher-Current Auxiliary Loads
  Provides greater continuous output capability than lower-current models in the Orion-Tr low-power range for compatible equipment with increased DC power requirements.
