Generator output is a goal usually set to 115 VAC across 3 phases at 400HZ, load expectations are commonly 60,90 and 120kva and probably more in the future.
The comon goal in the engine CSD/GEN, APU/GEN and IDG is to maintain that 115vac at 400hz. Most are set up with mechanical devices designed to maintain general HZ compliance and are tweaked by electrical devices in the aircraft to maintain 400hz.
