Frequency converters are required in situations where equipment operates at a frequency other than the standard 50Hz utility supply.

Typically this might be the following types of equipment:

  • 60hz American electrical equipment
  • Industrial process equipment
  • Military electrical equipment
  • Aircraft electrical systems
  • Test labs
  • University labs

Siel Energy Systems offers a range of 60Hz and 400Hz frequency converters:

  • The MFC 400 converts a 50 or 60Hz input to a 400Hz output,
  • The SAFEPOWER TM or TT FC converts a 50 or 60Hz input to either a 60 or 50Hz output.

MFC400 Frequency Converters

In the case of the MFC400 series, a 50 or 60Hz input supply is converted to a 400Hz output supply.  Double conversion technology is used, (VFI SS 111 voltage and frequency independent compliant with IEC EN 62040-3), with an integrated output transformer to ensure the galvanic isolation of the load.

The output voltage is 208 Vac three-phase (200/115V versions upon request). Power conversion topology is based on high-frequency IGBT technology and digital control.

MFC400 frequency converters are ideal for;

  • Industrial processes.
  • Military applications.
  • Avionics workshops.
  • Aircraft ground power.

SAFEPOWER Frequency Converters

SAFEPOWER FC series converts a 50 or 60Hz input to either a 60 or 50Hz output.   Proven IGBT technology is combined with an OUTPUT transformer providing galvanic isolation of the load from the DC circuits and a solid point for referencing the AC output to earth.

Systems use double conversion topology (VFI-SS-111; voltage and frequency independent compliant with EN62040-3).

Field proven, SAFEPOWER FC demonstrates high levels of short circuit capability, reliability, high efficiencies, ruggedness and flexibility designed to suit individual customer requirements throughout a wide variety of applications, including;

  • Industrial processes.
  • Shore to ship power.
  • Military applications.
  • Avionics workshops.
