The transformer Adapter OBD2 (24V/12V) is a voltage converter that converts the 24V power supply from the OBD2 port in heavy commercial vehicles, such as trucks and buses, to a stable 12V output. This Adapter enables diagnostic equipment specifically designed for 12V passenger car systems to be safely connected to vehicles with a 24V electrical system. The construction is aimed at bridging the voltage differences between different vehicle categories.

Using this Adapter prevents damage from overvoltage to 12V diagnostic testers, scanners, or other reading equipment. By reducing the voltage, the converter ensures a safe and stable connection, allowing technicians to work with one type of diagnostic tool on both light and heavy vehicles. The Adapter is equipped with a standard 16-pin J1962 OBD2 connector for broad compatibility with common vehicle ports and diagnostic cables.


Application and functionality:

This Adapter is designed to expand the compatibility of diagnostic equipment and protect the equipment.

  • Voltage conversion: Converts the 24V input voltage from the OBD2 port of a heavy vehicle to a safe 12V output voltage.
  • Protection of equipment: Prevents damage to 12V diagnostic devices, such as scan tools and code readers, that are not designed for the higher voltage of commercial vehicles.
  • Plug-and-play: The Adapter requires no installation or configuration. It is connected directly between the vehicle's OBD2 port and the diagnostic tester's cable.
  • Universal connector: Uses the standardized 16-pin J1962 OBD2 connector, ensuring wide applicability across various brands of trucks, buses, and diagnostic equipment.
