MVF23 Series

MVF23 Series Medium Voltage Drives

Delta MVF23 series medium voltage drives have built-in advanced flux-oriented vector control techniques with or without speed sensors.The high speed accuracy and fast dynamic response against load fluctuation are suitable for different types of load in the industry. The versatility of functions and protections make it easy to be integrated with field control needs thus to fulfill different applications. The drive is easy to use in terms of controlling pumps, fans, compressors, conveyors and many other variable and constant torque applications.
