SSC 90/600 Solid State converter changes the industrial frequency 380V

50Hz into 115V/200VAC 400Hz for aircraft use. SSC 90/600 can supply 90 KVA power rating, one 400Hz,115/200V AC output and one 28V 600A DC output.

The flexible design allows the GPU to be setup for either bridge, fixed or trailer mounted. The advanced SV-PWM technology, micro-processor based intelligent control system gives low distortion and good dynamic characteristics.
