Frequency Converter Unit
FCU
The Astronics Frequency Converter Unit (FCU) provides frequency conversion of variable frequency aircraft power. Recent trends in aircraft power systems use variable frequency (VF) generators instead of fixed frequency of 400Hz. While the majority of aircraft loads can use VF power, select loads still exclusively require 400Hz and are best addressed by the use of FCUs. The FCU performs the task of converting the power line frequency by leveraging recent advances in solid-state technology to provide dramatic improvements in performance over traditional frequency converter solutions.
