But a powersupply could be made to deliver say one.1A continuous present-day at powerup, and swap to constant-voltage method the moment 5V is achieved. From then on it is going to shutdown when 1.2A is touched...

The plots also demonstrate the frequency spectrum in orange, from 0 for the remaining to 230 kHz at the correct. The specified graph might have the orange spectrum in close proximity to The underside of your screen.
