| Control system (BLCT-5M) for resistors-based vehicles | ||||||||
|
||||||||
The microprocessor control unit is build within a 19" rack,
having 5 electronical cards connected through a backplane. Its
main task is to command the vehicle's driving contactors, as well
as the progression and the regression of the resistors units for
traction and electrical braking, according to traction/braking
pedal position and the motor current. |
