The OBD2 (24V/12V) transformer adapter converts the 24 V power supply of the OBD2 port on a truck, bus or commercial vehicle to 12 V. This lets you connect a 12V diagnostic tool without the power supply being too high.
The display shows the output voltage and the current drawn by the connected device. The adapter only adjusts the power supply; whether your device can read the vehicle depends on the protocols and software of that device.
HIGHLIGHTS
POINTS TO NOTE
Applications and functionality
The adapter is intended for users of a 12V diagnostic tool who want to connect it to a 24V vehicle with an OBD2 port.
Functions
- Converting power supply: 24 V to 12 V.
- Monitoring: Voltage and current on the display.
- Protecting the device: No 24 V on a 12V device.
How to use it
- Connecting: Plug the adapter into the OBD2 port of the 24V vehicle.
- Checking the display: Check that the output shows approx. 12 V.
- Connecting the device: Connect your 12V device to the adapter.
- Ignition on: Switch the ignition on and start the diagnosis.
Special features and capabilities
What makes this transformer adapter practical:
- Immediately visible: You can see whether the power supply is correct.
- Protection: Prevents damage from excessive voltage.
Compatible devices and vehicles
The adapter is intended for:
- 12V diagnostic tools: Testers, dongles and VCIs with OBD2.
- 24V vehicles: Trucks, buses and commercial vehicles with 16-pin OBD2.
Check that your diagnostic tool supports the protocols of the vehicle; the adapter does not translate data.
