Aviation Frequency Converters 20-200KVA

PCTI's Solid State 400Hz Frequency Converters

PCTI’s 400Hz Frequency Converters are designed for use on airports and airfields, where power needs to be run out to planes in the hangar and over the tarmac. Our mobile carts have wheels, which make them easy to maneuver around obstacles and bring to wherever the customer needs to supply power. Our Freestanding cabinets provide consistent power and compliment any hangar that needs to maintain any aircraft residing there.  These units are designed to take the standard 480VAC 60HZ or 380VAC 50Hz and convert it to 115/200VAC 400Hz for standard aircraft use.

For more information, contact PCTI about our solid state frequency converters for more details. If you need help in specifying your frequency converter, request a quote or download one of our 400Hz frequency converter brochures:
