Voltage converter from 24 V to 12 V: input (truck) 24 volt 15-pole. Output 12 V - 13 pin. Compact plug with Autodetect, thus independent detection of the bus system
Universal voltage converter: the adapter is suitable for vehicles with and without CAN bus system. Up to 60 watts continuous load. Can also be used for tractors, off-road vehicles, cars, trucks, agricultural and construction machines
European standard: ISO 12089 is a standard for electrical trailer connectors in the commercial vehicle industry. It is designed to replace ISO 11446 standards. The 15-pin system can transmit the same functionalities between towing vehicle and trailer with just one plug as the previous system consisting of two connectors.
Easy installation: reduces the voltage supply for the trailer lighting from 24 to 12 volts, so 12 volt powered trailers can be connected to a 24 volt towing vehicle (truck, tractor, etc.) without further modification. Converts only when a receiver is connected to the adapter.
1 year warranty - 1 x 15 pin 24 V to 13 pin 12 V voltage reducer. Regardless of whether you have any problems before or after your order, you can contact us by email at any time. We will do our best to solve your problem.
