Tru Blue 4,000w frequency converter STC approved on Gulfstreams
The TFC4000 provides 15 per cent more power than the frequency converters it is designed to replace and provides reliable power to outlets throughout the aircraft.

True Blue Power has an STC for its TFC4000 frequency converter on Gulfstream G450, G550, G650 and G650ER aircraft. The TFC4000 is the lightest and quietest frequency converter in its power class. It provides up to 4,000 watts of wall outlet power to cabin equipment and 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. The validation process with the TCCA, EASA and ANAC has already been completed.

“The TFC4000 provides 15 per cent more power than the frequency converters it is designed to replace,” says Van Winter, vice president of marketing and aftermarket sales. “It provides reliable power to outlets throughout the aircraft, supporting electronics and appliances, from laptops and computer systems to coffee makers, galley equipment and in-flight entertainment systems.”

Weighing in at only 18.9lbs (8.57kg), the TFC4000 is 30 per cent lighter than competing converters, making it the lightest frequency converter in its power class. It is also the quietest on the market, as independent temperature and speed-controlled fans significantly reduce noise.

Silicon carbide technology, custom magnetics and plenum cooling increase efficiency and protect internal components from moisture and contaminants commonly found outside the pressure vessel and in non-temperature-controlled locations, like the ‘Hell Hole’.

True Blue Power partnered with Sterling Helicopter, a certification resource based in Pennsylvania, to develop the TFC4000 STC for the Gulfstream G450, G550, G650 and G650ER aircraft.

“Having reliable cabin power is important, and True Blue Power's frequency converter is the answer,” says Sterling Helicopter director of engineering Edward Allen. “The TFC4000 significantly reduces maintenance and replacement costs and is much quieter than the current frequency converter it replaces, making it the best overall value available.”
