High Power Motor Drives

MVD1000 Series

High Power Motor Drives - MVD1000 Series

Delta medium voltage drive is a high-efficiency, compact, high reliable and energy-saving solution. According to demand of different motors and loads, Delta provides general type and vector control type MVDs, which have a broad range of applications in segments such as power generation, oil & gas, mining, metals, cement, and public facilities. MVD is used to drive medium voltage motors loaded for instance by fans, pumps, compressors, mills, crushers, mixers, and extruders. MVD provides process control, so it can increase production efficiency, reduce energy loss, improve equipment protection, and reduce maintenance cost.

Delta provides customers complete solutions with easily operated variable frequency drives.
