Eaton e-heater 48 V programmable power electronics control unit

Eaton’s eMobility business has introduced a 48 V programmable power electronics control unit for electrically heated catalysts that can be used by commercial vehicle manufacturers to meet tightening global emissions regulations. Rapidly warming up the exhaust aftertreatment catalyst, and keeping it warm during low engine load operation, is essential for optimal performance to reduce harmful nitrogen oxide (NO_x) exhaust emissions.

The air-cooled electric catalyst heater controller is part of Eaton’s broader 48 V electrical system portfolio, which contains several technologies that allow manufacturers to integrate 48 V architectures in next-generation vehicles. The e-heater controller is designed to receive power commands from the aftertreatment system and provide soft-start and soft-stop capabilities for assisting in maintaining system voltage control, as well as diagnostic feedback of the heater element.
