STA 1 FU/I Series with Frequency Converter

Our operator with frequency converter for 230 V single-phase networks. The frequency converter handles the generation of the required three-phase network. And compared to the STA 1 operators without FC, it opens doors twice as fast. In combination with the soft start and soft stop function, the operator gently brakes the door at the end positions so that harmonious, low-wear door operation is guaranteed. The speeds for opening and closing the doors can be set variably.
