Überblick
An excitation device designed for the excitation and monitoring of onboard power generators.
The exciter draws energy from the 24 V battery of the onboard power grid and delivers excitation current to the brushless generator. Different excitation profiles are used for drive-mode and braking-mode. The device operating mode is controlled by the vehicle's main computer.
