powerdrive md2Range: 45 to 2800 kW

Leroy-Somer's range of high-power modular drives is evolving in the shape of Powerdrive MD2 - an even more compact and user-friendly drive. The combination of power modules and the choice of cooling method make it possible to create multiple optimized configurations: 6-pulse, low-frequency harmonics, regenerative or DC bus solution. Powerdrive MD2 provides high-performance control of motors, making it the ideal choice for any industrial or commercial variable speed application up to 2800 kW (pumping, ventilation, compression, etc).

For artificial lift, Leroy-Somer has developed a dedicated offering with options for export pumps, PCP, ESP and ESPCP, Onshore and Offshore installations.
