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.
