FLYTEK GPU – 400Hz GPU | 45 KVA – 180 KVA

FlyTek GPUs (Ground Power Units) contain power ratings from 45KVA to 180kVA making this product line perfect for any commercial, industrial or military application involving a variety of aircrafts. Through innovative research and development, FlyTek GPUs are efficient, easy to operate and maintain. They use double conversion technology with an integrated inverter output transformer to ensure galvanic isolation of the load. Dependent upon rating, these units are available in mobile, towable, and fixed configurations. In addition, FlyTek offers 28VDC/AC combination units.
