What is a trailer voltage converter and when do you need one?
When connecting a trailer, semi-trailer, or flatbed to a towing vehicle, it's critical that the electrical systems of both are compatible. This is where the trailer voltage converter comes into play, a component that ensures the trailer's lights and signals function properly, preventing malfunctions, signal errors, or system damage.
What is a voltage converter?
A voltage converter is a device that adapts the electrical voltage between two different systems, for example:
- From 24V to 12V : if the truck works at 24V but the trailer is prepared for 12V.
- 12V to 24V : less common, but necessary in some configurations.
This adapter protects the trailer's electrical components (lights, turn signals, fog lights, etc.) from overloads and ensures that the signals arrive correctly from the towing vehicle.
When do you need a converter?
You should install a voltage converter when:
- Your vehicle is 24V and is towing a trailer with a 12V system.
- You connect a European trailer to a vehicle with different regulations .
- You have detected signaling failures when connecting rear or side lights.
- You work with a mixed fleet or vehicles from different origins.
How do you connect?
The converter is usually connected between the vehicle's power outlet and the trailer's power outlet , using standard 7- or 13-pin connectors. Many models are plug & play and ready to operate without complex installation.
