MVW 01 - Medium Voltage Variable Frequency Drive

WEG Medium Voltage Variable Frequency Drives are designed with state of the art technology and use a multilevel structure with high voltage IGBT's (6.5kV) reducing the motor harmonic currents to extremely low levels. The input rectifier configuration with 12-pulse or 18-pulse results in high power factor fully meeting IEEE-519 requirements. The MVW-01 is designed with multiprocessing control architecture and uses a 32-bit high performance processor (64-bits bus) with floating point capability, ensuring high performance control of the drive and motor. The MVW-01 follows the same programming philosophy as the LV WEG drive, resulting in a simple speed variation solution for MV applications. The MVW-01 drives introduce remarkable innovation to the segment of medium voltage speed variation, combining robustness, simplicity, reliability and safety in a compact solution with the latest generation technology.
