Variable frequency drives 7,5kW A550
Variable frequency drives 7,5kW A550 are universal integrated devices of economy class, characterized by simplicity and clarity of control elements. Fully adapted to client requirements, developed on the basis of many years of experience and user suggestions. VFD A550 is fully pre-programmed and ready for immediate use when properly connected to the mains. Control is possible directly from the panel or externally. To start the inverter, user simply has to press the START button and turn the built-in knob around its axis. The inverter automatically accelerates or decelerates the driven electric motor.
