Case Studies

There is a requirement within the Commercial Vehicle Industry for vehicles equipped with 24 volt electrical systems to tow trailers that have 12 volt lighting circuits. This application requires the vehicle to be fitted with an adaptor to convert all of the 24 volt lighting circuits to 12 volt operation.

The requirement was for a universal timer that could be preset by the installer to different time periods to suit the individual application. A further requirement was for versions that could be used on 24 volt and 12 volt vehicle electrical systems. As is the case with any automotive product, the design had to be robust both electrically and mechanically.

Bridgwater Electronics was commissioned to design and develop a speed alarm that could be set to operate at a preset speed, alerting the operator of the vehicle that the safety speed limit had been exceeded.
