MVF20 Series

MVF20 Series Medium Voltage Drives

Delta’s MVF20 series is a highly integrated and high-performing variable-frequency device for general-purpose motor control applications. It provides excellent variable-speed control for relevant system fans, pumps, and compressors. The MVF20 series cabinet features an in-parallel cabinet design and is an MVD with high power density and a high space utilization rate. The drive is easy to use in terms of controlling pumps, fans, compressors, conveyors and many other variable and constant torque applications.
