REO is an original manufacturer of high quality power equipment, including electronic controllers, components and electrical regulators.
Dieke develops and manufactures high-power transformers and chokes for drive and railway engineering applications.
The power ratings range from 5kVA up to 500kVA. The working frequencies range from 16.66Hz up to 10kHz.
Using the latest nano-crystalline technology NIEKE can offer linear and toroidal components for higher frequency ranges, with potential isolation. These space-saving, lightweight filters and transformers are being used more and more in drive engineering applications, particularly for transport.
