[ENHANCEMENT] add delayed reaction for power panic

[JordyDH]

Printer model

XL Multi tool

Describe the enhancement

We use our prusa XL non stop for printing services. And we use a UPS (ecoflows) as power backup. Problem is that these systems and a lot of ups system interupt the high voltage for a couple of ms and this is enough to trigger the DELTA powersupply power panic.

right now we have bypassed the power panic functionality by adding a switch to the opto coupler.

We tested this and the printer keeps printing without any artifacts with the ecoflow as battery backup.

i think this would be a advanced feature where the user can select a fixed time that the power panic needs to be triggered to activate this.

This should only be a couple of miliseconds.

Expected functionality

So in the settings add a field for delayed power panic reaction from 0ms to for example 50ms ( this is on the high side).

when power panic from delta power supply is detected and it keep being detected for the set amount of time then activate power panic in the firmware.

By doing this (and yes this would be a expert feature) user will be able to use “cheaper” UPS units to continue printing during power outages
