By sequentially or serially operating the ASPM to control the automatic handbrake release, the instantaneous power consumed on the trainline 10 can be controlled.
  • the dump car and the hand brake are just two examples of auxiliary functions, devices or equipment that can be powered and controlled by the Auxiliary Smart Power Module. Other auxiliary functions or equipment may also be powered or controlled.
