Buying 6SL3111-4VE21-6FA1 from Flexa Systems
Buy the Siemens 6SL3111-4VE21-6FA1 SINAMICS VFD, available on request in brand new or refurbished condition, or send yours to Flexa Systems for repair. This SINAMICS drive carries an AC 400V voltage rating, an 18 A current rating and a 16 kW power rating, which places it on motor-driven equipment such as pumps, fans and conveyors running from a 400V supply. Before ordering, compare those three values with the plate on the drive you are replacing and with the motor it controls, because a mismatch in current or power can trip the drive or leave the motor short of torque.
