Digital generator set controller ATS-I

Digital controller generators/mains transfer switching ATS-I ATS-I power unit enables the switching control in Manual or Automatic mode. In manual mode operation it is possible to send, through a proper button, a stop and start remote signal to the generator. Genset/Mains switching is manually managed through the key selector. In automatic mode operation the power unit controls the net through the thresholds of operation for minimum, maximum voltage or phase failure. In case of operation, a contact for the generator remote start control is closed. When the power unit receives the signal of started generator, after having checked that the frequency and voltage are within the right values, it controls the closing of the group contactor. When the net voltage is returned within the limits, the power unit makes the Mains/Genset switching, and successively, after an adjustable time, it sends a stop signal to the generator. The voltage values on L1-L2-L3 (L1/N) phases and more others measures and information are showed on the display.
