Product description
Within the SIMOVERT MASTERDRIVES family, the Siemens Motion Control converter 6SE7021-4EP50-Z performs power conversion for three-phase motor drives. Its Compact-PLUS design combines the AC-AC power section and the device's internal air cooling in one compact unit. The AC-AC version accepts the three-phase mains voltage directly and provides the regulated three-phase output for the motor. The three-phase input voltage range is 380 to 480 V. With a rated output current of 14.0 A and a rated motor power of 5.5 kW, the device belongs to the corresponding power class of the Motion Control range. The complete order number remains the decisive identity feature of this converter. The output frequency range from 0 to 400 Hz is a central operating parameter for the connected drive. A separate 24-V-DC auxiliary power supply is provided for the permitted range from 20 to 30 V DC. The three-phase output voltage ranges from 0 V to the respective rated input voltage. This combines mains input, power conversion and motor control in the same Compact-PLUS unit. An integrated fan is provided for heat dissipation, while the housing is specified with IP20 protection. Motion Control denotes the specific device family within the SIMOVERT MASTERDRIVES system. The mechanical data complement the electrical classification with a fixed Compact-PLUS housing. It measures 135 × 360 × 260 mm in the order width, height and depth. A rated input current of 12.6 A is specified. The DC link operates from 510 V −15 % to 650 V +10 %. The power factor is cos φ1N = 0.97, and efficiency is above 0.97. Net weight is 11.1 kg.
