Eaton's 48V E-Heater Power Electronics Controlleris an air-cooled electric catalyst heater that can receive power commands from the aftertreatment system and offer soft-start and stop capabilities to help maintain system voltage control to 48-volt vehicle systems. Additionally, the controller can recieve diagnostic feedback from the heater element. The system can handle a total of 200 amps of load current to either one or two independent heating coils in the vehicle aftertreatment system, resulting in a 75% NOx reduction, the company stated.
