    KBR multicomp F144-3 6DO/6RO Functional principle Functional principle of the controller The multicomp F144-1V1C6DO6RO-3 hybrid controller has 12 outputs to control capacitive compensation stages. Outputs 1 to 6 are designed to control thyristor modules (by optocoupler outputs) and outputs 7 to 12 to control capacitor contactors (by floating relay contacts).
  • Page 9 Functional principle KBR multicomp F144-3 6DO/6RO After an adaption time of 60 seconds, the thyristor stages are switched by contactor stages of the same size. This guarantees that the fast control charac- teristics can be kept. The integrated temperature measurement input monitors the temperature in...
