Master FC400 — static frequency converter 50/60→400 Hz, 30–125 kVA
Country: Italy · Model: Master FC400
The Master FC400 static frequency converter turns a three-phase 50 or 60 Hz supply into 400 Hz, 208 V and comes in 30–125 kVA. It serves ground power for aircraft at airports, radars and flight control systems, ships, military sites and test benches.

Description
Ratings run 30, 60, 80, 100 and 125 kVA, and the output voltage is adjustable within 200–215 V to make up for drop in a long cable to the aircraft stand. The VFI-SS-111 double conversion stage is built on IGBTs, so output frequency and voltage do not depend on the input supply. An output transformer gives galvanic isolation, leaving the onboard network unconnected to the ground grid by phase or neutral. The rectifier soft-starts and puts few harmonics back into the input supply, so the converter runs easily from a generator. Battery backup is available, so a 400 Hz consumer keeps power through a short mains loss. The 125 kVA model takes 0.86 m² of floor space, under a square meter for the whole cabinet.
How to choose
Size the rating from the peak 400 Hz load with margin for onboard inrush, picking from 30, 60, 80, 100 and 125 kVA. When one converter feeds several stands or benches, add their loads with simultaneity in mind. If a site needs 50 to 60 Hz conversion for a small load rather than 400 Hz, the Sentinel Dual Marine at 6 and 10 kVA in frequency converter mode will do.

FAQ
What output voltage does the Master FC400 400 Hz converter give?
Three-phase 208 V, adjustable over 200–215 V, at 400 Hz.
How much floor space does the 125 kVA Master FC400 take?
The 125 kVA model takes 0.86 m².
Can a 400 Hz frequency converter run from a generator?
Yes, low input harmonics and the rectifier soft start make generator operation easier. The input is three-phase, 50 or 60 Hz.
Does the Master FC400 have galvanic isolation?
Yes, an output transformer after the IGBT inverter of the VFI-SS-111 stage gives it.
Which power ratings does the Master FC400 come in?
30, 60, 80, 100 and 125 kVA, all with a 400 Hz, 208 V output.
