WEG Medium Voltage Variable Frequency Drives


WEG is a world class manufacturer of Variable Frequency Drives, also known as Variable Speed Drives. For medium voltage motors WEG has the MVW-01 Medium Voltage VFD. The MVW-01 is a highly versatile product that can provide speed control for motors up to 7,000 HP with input voltages from 2300V to 6600-6900V. The MVW-01 combines the simplicity of control found in WEG’s low voltage VFD line with robust hardware to provide the user with a product that is simple, reliable and safe to use. WEG has reduced the number of components typically found in a Medium Voltage VFD resulting in higher efficiency, reliability and total cost of ownership. A myriad of communication options including DeviceNet, Modbus, Profibus-DP and Ethernet/IP allows the MVW-01 to be integrated into existing systems. The input rectifier has a multipulse diode configuration giving the power supply a high power factor meeting IEEE 519 requirements.
