| Static frequency converter (CFTxx) |
|
The
frequency converters range is dedicated for induction (asynchronous)
motors driving with rated powers up to 45kW, and rated voltage of
380Vac. The technical solution flexibility and the tuning performances
ensure the compatibility with any application and project customization
is easily made. Converters with custom powers, output and input
voltages are available on request. |
