OBD 24V → 12V Voltage Step-Down Adapter

Converts 24V OBD systems to 12V, allowing diagnostic devices to be used safely. It is designed for connecting 12V OBD devices to heavy-duty vehicles with 24V electrical systems, such as trucks, tractor units, dump trucks, and buses.

Featuring a standard OBD-II 16-pin connection, the voltage converter is connected between the vehicle's OBD socket and the diagnostic device. It reduces the vehicle's 24V input voltage to a 12V output voltage, helping the connected device operate at the appropriate voltage level.

Using 12V Diagnostic Devices in 24V Vehicles

While heavy-duty vehicle electrical systems generally operate at 24V, many diagnostic and OBD devices are designed for a 12V supply voltage. This adapter reduces the 24V supply to 12V, helping diagnostic devices to be used safely in heavy-duty vehicles.
