Power management company Eaton announced that its eMobility business introduced a 48-volt programmable power electronics control unit. This equipment is for electrically heated catalysts that can be used by commercial vehicle manufacturers to meet tightening global emissions regulations. The control unit quickly warms up the exhaust aftertreatment catalyst and keeps it warm during low-engine-load operation. This process is essential for optimal performance to reduce harmful nitrogen oxide exhaust emissions.
The air-cooled electric catalyst heater controller is part of Eaton’s broader 48-volt electrical system portfolio. Eaton’s family of electric heater power electronics controllers are for solutions between 2 kW and 15 kW of power and operate with up to 99% peak efficiency.
This controller is designed to:
- Receive power commands from the aftertreatment system
- Provide soft-start and soft-stop capabilities for assisting in maintaining system voltage control
- Deliver diagnostic feedback of the heater element
