KBR multicomp F144-NC-1V1C6DO6RO-2Functional principle
switch-o 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.
For low load operation (secondary measuring current under the limit (<15 mA)), the
stages are switched o after 1 hour.
The programmed values are saved on an EEPROM and will thus not be lost after a mains
failure.
The measuring cycle of the controller for recording the necessary network parameters
takes approx. 20 ms.
