    Default Active PFC related question.

    I am on 230V.

    How much drop in voltage will make the PSU shut itself down?.

    If it's a full range APFC, it should keep going until it's under 90-100V.
    If it's a 220v-only APFC (I've heard such things exist, here in the USA it's full range or go away) then I don't know.

    My guess would be around 200V, but I could be wrong.
    No wonder it doesn't work! You installed the coils backwards

    230V-only APFC usually cuts off at around 180V. Some of the implementations don't set the strict input UVP, and if the switchers and the boost diode can take it, will work all the way down to ~85V.
    Careful what you wish for... You just might get it.

    You dont need to predict anything because my PSU is in the signature.

    Will check.

    The CX430 should work down to 90V. Certainly to 100V

    They sell that PSU in Japan, so you know it can do 100V w/o problem.
