LEROY-SOMER offers a modular concept with their new generation of high-power variable speed drives, POWERDRIVE, a versatile and compact range up to 900 kW integrating only those functions required by the application.

POWERDRIVE is created by a combination of modules, associated with electronic control boards. These modules are assembled on a chassis or in standard cabinets.

Numerous configurations are available, according to the application: 6-pulse, multi-output 6-pulse, 12-pulse, regenerative or DC bus solution.

Several control modes are possible for controlling asynchronous, synchronous magnet and HPM Hybrid Permanent Magnet motors.

Setup is simplicity itself, due to the keypad on the front panel or thanks to the PowerSoft program which also offers a parameter-setting wizard.

A preventive self-test is performed on each start-up. Any faults are then detected (motor phase to earth, short-circuit, etc) before causing irreparable damage.

An internal communication interface module in the POWERDRIVE can generate alert or information messages for remote maintenance/ remote monitoring of machines.

POWERDRIVE for any application! Pumping, ventilation, centrifugal treatment, compressors, winding/unwinding, handling, hoisting, etc.
