MV1000 Medium Voltage AC Drive

Dec. 16, 2013

Designed for energy savings and improved process control, the MV1000 drive combines compact modular design, high efficiency, low harmonics, and industry leading MTBF into a medium voltage drive solution that is compatible with Yaskawa’s 1000 series low-voltage AC drive products.

 

Yaskawa’s Smart Harmonics Technology reduces input Total Harmonic Distortion (THD) to less than 2.5% without filters which exceeds the requirements of IEEE519-1992 by almost 50%.
