  • Page 8: Functional Principle Of The Controller

    KBR multicomp F144-NC-1V1C6DO6RO-2 Functional principle Functional principle of the controller The multicomp F144-1V1C6DO6RO-2 hybrid controller has 12 outputs to control capaci- tive 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 fl oating relay contacts).
  • Page 9 Functional principle KBR multicomp F144-NC-1V1C6DO6RO-2 switch-off hysteresis can be increased to up to 150% of the lowest stage power. 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 characteristics can be kept.
