Master FC400

Power Range

30 - 125 kVA
  • 3:3

30-125 kVA 400 Hz

Master FC400 series static frequency converters are available from 30 to 125 kVA, with 50 or 60 Hz input and 400 Hz output. The result of extensive experience acquired in the UPS industry, the Master FC 400 series is distinguished by the use of technologically advanced components and for excellent reliability, ease of maintenance and ease of operation.
The Master FC400 series uses double conversion technology (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 from mains disturbances under all conditions.
The output voltage is 208 Vca three-phase (200/115V versions upon request). Thanks to high frequency IGBT technology and digital control, Master FC400 frequency converters are ideal for airport, military and naval applications.

Enquire About This Product



The Master FC400 was designed to reduce to a minimum the impact on the mains or generator located upstream, thanks to the low harmonic content input and the progressive start of the rectifier. These features make the Master FC400 frequency converters especially compatible with generators.

The Master FC400 requires a small space for installation (only 0.86m2 for a 125kVA model).
The main assemblies of the UPS can be easily accessed for maintenance, via the removable front panel. Fans located in the top of the UPS cabinet, eliminate the need for side or rear access, and allow the UPS to be placed against a wall.

Master FC400 provides additional protection for a wide range of applications, including:

  • Powering airplanes in airports
  • Radar and flight-control systems
  • Naval applications
  • Military applications
  • Power for test benches.
