The FAA has issued a supplemental type certificate (STC) for the installation of True Blue Power’s TFC4000 frequency converter on the Gulfstream G450, G550, and G650/650ER. In addition, the STC has been validated by EASA and Brazil’s ANAC. True Blue Power partnered with Sterling Helicopter to develop the STC.
The frequency converter provides power for cabin power outlets for plugging in computers and for galley equipment and in-flight entertainment systems. According to True Blue Power, the TFC4000 is a direct “and more reliable replacement for existing GE Aviation Systems 717220-1, 717220-2, 717220-2R and Avionic Instruments 1-002-0102-2444 and 1-002-0102-2052 frequency converters.” It also provides 15% more power than the units it replaces.
Other benefits include lower noise with independent and speed-controlled fans; at 18.9 pounds, it is 30% lighter compared to other frequency converters in its class; and it features improved efficiency and protection “from moisture and contaminants commonly found outside the pressure vessel and in non-temperature-controlled locations, like the ‘hell hole,’” thanks to “silicon carbine technology, custom magnetics, and plenum cooling.”
