    LED 1-10v Dimming doesn't go lower then 4v instead of 1 volt when dimming down.

    Hello Could anyone help and explain why de output of the VSd gives out a signal of minimal 4v when trying to dim my LED panels. Is there a maximum of drivers with a 1-10v dimming option that you can hook-up to one single dimming port?

    I have 12 dimmable drivers that I want to dim at once using one variable speed dimming outlet on my APEX 2016. Can I just tie them together on one port? Or is there a maximum of drivers that I can put on one port. With 12 lamps hooked to one channel of the Variable speed dimming port I cannot dim down below 4v. I would like to get it to 1V.

    Could anybody help/and expain.

    It depends on the driver but most max out between 4 and 6 allowed on a single varspd port. I would split it to 3 chains and put more of certain spectrums on each chain to give you more control.

    You might be an engineer if...You have no life and can prove it mathematically.
