Hi Community, I'm using P3041 board and I want to verify the following things. Can someone help me?

- How to verify that the hold-up capacitor can sustain the operation for minimun of 150 milliseconds?

- How to verifiy the coherency of the discrete lines used to report the status of the main 28V power.

PWR_OK: CPU runs on external power, hold-up capacitor is fully charged.
PWR_LOW: CPU runs on the hold-up capacitor.
PWR_DWN: power-off is imminent, in about 5 msec.
