Master FC400 UPS 30-120kVA

A 400Hz frequency converter version of the Master Plus UPS

Frequency converter 50/400 Hz
• Output voltage: 208 V – 3F
• Galvanic isolaltion
• Two versions to reduce input harmonics
• Applications:airport, military and naval


The MASTER FC400 series static frequency converters are available from 30 to 120kVA, with a 50 or 60Hz input and a 400Hz output. The product of extended experience acquired in the UPS industry, the MP FC 400 series is distinguished by the use of technologically advanced components and for excellent reliability, ease of maintenance and easy 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 output transformer inside in order to ensure the isolation of the load from network disturbances in all conditions.The output voltage is 208Vca three-phase(200/115V versions upon request). Thanks to high frequency, digitally-controlled IGBT technology, the MASTER FC400 static converters are ideal for airport, military and naval applications.Minimum impact on network – easy source MP FC 400 technology removes the problems of over sizing upstream power sources, whilst improving load power factors and current harmonics. The UPS features the latest input current absorption techniques including progressive rectifier start-up and the option to reduce battery charging currents

These features make MP FC 400 one of the most generator compatible and environmentally friendly UPS available.Ease of Installation and Maintenance

MASTER FC400 only requires a small space for installation (only 0.86m2 for 120kVA). 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 planes in airports• Radar and flight-control systems• Naval applications• Military applications• Power for test benches

• Input isolation transformer
• 2 Programmable relay contact boards
• Remote LCD mimic panel
• Remote Graphic Panel
• Higher protection level than IP20
• Parallel.
