Nidec Leroy-Somer, world leader in alternators from 10 to 35,000 kVA, has been manufacturing a range of special frequency products destined for the aircraft industry, for the last 30 years.
Expertise in design and manufacturing ensure that each Nidec Leroy-Somer product meets the technical requirements of this exacting application.
The 400Hz alternators are brushless, self-excited generators (Shunt excitation), with the D550 digital AVR fitted as standard.
They meet the principal international standards, notably: IEC 60034-1.
Our latest D550 Digital AVR is compatible with all our 400 Hz alternators.
It is equipped with several advanced protections and integrates a visual interface (EasyReg Advanced Software), that enables users to read configuration values and parameters.
The D550 has also been optimized for grid parallel operations and complies with the latest grid code regulations.
