PowerPro Extreme 12 starters from Leece-Neville have a higher level of dependability and performance through new iRelay – “intelligent relay” – ­technology that provides programmable protection features that are fully customizable to OEM requirements and added protection against early life failures caused by a wide range of cranking issues, pinion and ring gear tooth abutments, and more.

“Our engineering teams worked very closely with global engine manufacturers and fleets to develop our new iRelay technology,” said Jonathan Smith, assistant director of sales and marketing at Prestolite. “This new capability builds on our commitment to ensure our reliable starters are further protected from premature failure while increasing reliability and performance on the job site, particularly in extreme operating conditions like construction and mining.”

The PowerPro Extreme 12 starter with iRelay technology enables flexibility to adjust specifications to meet OEM requirements for both single and dual starter applications. The feature is a standard SW030 starter control relay with an added electronic module that provides programmable “intelligent” protection using small microprocessors.

iRelay technology helps to protect the PowerPro Extreme 12 starter from premature failures commonly caused by excessive cranking, under-voltage cranking and pinion and ring gear tooth abutments. Additionally, iRelay technology can help to provide protection from starter engagement into a running engine, under-speed cranking and more.

For dual or triple starter applications found commonly on generators, mining equipment and more, the PowerPro Extreme 12 starter with iRelay technology includes functionality to prevent single starter operation* and helps to monitor starter synchronized operation. In dual or triple applications, iRelay also can help to prevent the engine ring gear from pinion milling. 

The PowerPro Extreme 12 starter features include: 

• 24V, 12kW starting power ideal for diesel engines up to 40L in single configuration, up to 85L in dual configuration and above 90L in triple configuration
