The World's Largest Independent Producer of Alternators 1 - 5,000kVA
Products / 400Hz


Our 400Hz alternator range is predominantly used in the aircraft ground support market. We are able to offer units for ground power supplies from small 5kVA 14 pole units through to large 200kVA 26 pole units.

The new series of alternators at 400Hz is the result of our long experience in this sector and of diligent studies and researches aiming to keep pace with the technological development of an era where technology is the winning card. The  series has been designed to meet the more technological requirements of applications such as telecommunications, cogeneration, army and aeronautics sectors.

All the 400Hz alternators have a fixed inductor with skewed slots and a rotating inductor. The windings have a 2/3 pitch in order to reduce the harmonic content of voltage. The entire series is manufactured according to and complies with the most common specifications such as CEI 2-3, IEC 34-1, EN 60034-1, VDE 0530, BS 4999-5000, BS 2G 219, ISO 6858, MIL-STD-704F.

The UVR6-H400B regulator is an advanced compact electronic regulator used for 400Hz machines.
This regulator is equipped with low speed and overload protection with an adjustable intervention threshold, it has adjustable voltage stability and offers the possibility for a remote voltage regulation with three phase sensing capability.
