FREQUENCY CHANGER

750VA 50/60 Hz to 400Hz

The SPC6-750A solid state frequency changer converts 115 VAC 50/60 Hz to single phase 115 VAC 400 Hz sine wave power. The SPC6-750A is designed for use on avionic test benches to power radars, compasses, gyros, HSI's and to add 400Hz power to  flight simulator systems.

The SPC6-750A-230 and SPC6-750C are models available for 230 VAC  50 Hz operation.
