Victron Energy Orion-Tr 24/12-15 (180W) DC-DC Converter ORI241215200R

The Victron Energy ORI241215200R Orion-Tr 24/12-15 is a non-isolated DC-DC converter designed to convert a nominal 24V DC supply to a regulated 12.5V DC output. With a 15A continuous output and 180W nominal output capability, it provides an efficient solution for powering 12V equipment from compatible 24V electrical systems.

The Orion-Tr 24/12-15 operates across an 18–35V input range and delivers up to 20A maximum output current. Victron specifies 97% efficiency, low off-load consumption, screw-terminal connections, and IP43 protection when installed in the specified orientation. 

Key Technology

• 24V-to-12V DC Conversion
  Designed for applications where equipment requiring a 12V-class supply must operate from a compatible 24V DC electrical system.

• 15A Continuous Output
  Provides a continuous output current of 15A, supporting compatible DC loads within the converter's operating limits. 

• 20A Maximum Output Current
  Supports up to 20A maximum output current for the Orion-Tr 24/12-15 model.

• 97% Conversion Efficiency
  Uses synchronous rectification to provide high-efficiency DC conversion. Victron specifies 97% efficiency for the Orion-Tr 24/12-15.

• Wide 18–35V Input Range
  Accepts an input voltage range of 18V to 35V DC, allowing operation across the normal voltage variation of compatible nominal 24V systems.

• 12.5V Regulated Output
  Provides a specified 12.5V DC output for powering compatible 12V equipment from a higher-voltage DC source. 

• Low Off-Load Current
  Specified with an off-load current of less than 35mA, helping minimize unnecessary consumption when connected loads are not drawing power.

• IP43 Protection
  Provides IP43 protection when installed with the screw terminals oriented downward, according to Victron's installation specification.

• Screw-Terminal Connections
  Uses screw terminals for the DC connections, with Victron noting that no special tools are required for installation.

Best Uses

• 24V Battery Systems
  Ideal for supplying compatible 12V equipment from a nominal 24V battery bank or DC electrical system.

• 12V Accessories on 24V Systems
  Useful when lights, electronics, controls, communication equipment, or other compatible 12V loads need to operate from a 24V source.

• Vehicle Electrical Systems
  Suitable for compatible vehicle and mobile electrical installations where 12V auxiliary equipment must be powered from a 24V DC system.

• Marine DC Systems
  Provides DC voltage conversion for compatible marine installations using a 24V electrical system with 12V auxiliary loads.

• Battery-Based Power Systems
  Suitable for off-grid and battery-based installations requiring an efficient step-down conversion from a nominal 24V supply to 12V-class equipment.

• DC Distribution Applications
  Can provide a dedicated lower-voltage supply for compatible auxiliary circuits within a properly designed DC distribution system.
