Static Frequency converters 50Hz, 60Hz, 400Hz SFC 10 – 150kVA
Benefits, SOJITECH manufacture a variety of Static Frequency Converters. Static Frequency converters, convert the source power with a specific input voltage and frequency in to a different out voltage and frequency depending on what our clients may require. SOJI FC units can be used in a variety of applications: Civil and Military Aviation, Aeronautical industry, Maritime/Nautical Industry and manufacturing sector.
SOJI FC Static Frequency Converters (static or Solid-state) have no moving parts, except for the fans to cool the systems down, and are highly efficient units (up to 95% efficiency). Our High frequency IGBT Technology (Rectifier and inverter) guarantees a perfect sine-wave input with low THDi (THDi <1%) and unitary power factor (PF=1), perfect for all sorts of extreme electrical conditions (compatible with Genset output).
Specific communications and specialized enclosures may be developed for custom products.
Principles Of Working
The benefit of a 400Hz electric system resides in lowered dimensions and weight respect an analogous system to 50Hz or 60Hz.
