At Prestolite we consider ourselves specialists in alternators and regulator technology, with 108 years of experience.

The last decade has seen significant changes in alternator technology and the associated regulator technology.

Introduction of exotic irons and permanent magnets into rotor cores have seen up to 40% increase in output versus traditional iron cores.

Dual internal fan alternators offer improved cooling for stator and rectifier assembly, allowing better heat dissipation, increased output and a light weight compact design.

We are continuously working to innovate and bring you the next generation of charging and starting technology.

Should you have any questions regarding our product ranges or have any special requirements, please contact your Regional Prestolite Sales Manager or our Technical helpline.
