Product overview
Electrify auxiliary systems in vehicles with the T6 APD inverter system from KEB Automation. The T6 APD is designed for battery-electric and hybrid vehicles and meets requirements for mechanical and thermal properties, ambient conditions, EMC, safety and service life. The scalable, modular system integrates up to six inverter modules in three performance levels (rated output currents 16.5 A, 33 A and 60 A) and supports dynamic, energy-efficient speed and torque control. Integrated DC EMC filters and a Mobile Control Unit (MCU) with communication gateways enable reliable operation and integration into vehicle control architectures.
