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%.
