potentiomenter

question #1 whats the best brand of 100K potentiometer and where can I get it?

question #2 which type of potentiometer (if one exists) will dim 3 drivers (240/54) using only 1 potentiometer?

thanks in advance

well, i can tell you this much, i used the Bourns 50K for 2 meanwells, it was horrible. Im using 4 cobs, 2 different Ks, and now use 100K from zon for each K, and they are awesome,

this one?

20 pc ? how many dimmers are in there?

You can use 1 potentiameter ro dim as many drivers and you want, it just has to be rated high enough.

Yes, thats it, you get 20 dimmers, and 20 knobs, and they are smooth and flawless, at least the 2 i picked outta the bag, lol..

I did go with the Bourns, like suggested, and it didnt fluidly make the adjustment.

If you don't want 20 of them.. here is a link for just one and has worked for me

here is the driver

if im not mistaken its an AC driver ...it says ACL and ACN for live and neutral

I want to connect 3 of these drivers (likely using wago connectors) to one dimmer/potentiometer

anybody want to help me make sure I get the correct part?

im not sure how to determine the proper sized potentiometer to run all three drivers

One 100k potentiameter should dim 3 of those just fine

if I can use a std lutron dimmer from the hardware store im fine with that but I just don't want to use something that's going to harm the drivers

these drivers do have the built in dimmer leads....

so I don't need anything rated special?

I can just use the std 100K URBEST dimmers ?

Yes, you could also add a 10k resistor to each negative terminal but you should be okay

I would just try the 100k potentiameter by itself at first

Those are not what you want at all. You want ordinary 100K linear potentiometers.

Read the link posted above for help. There is a formula for figuring out what you need where k/n k ks the resistance and n is the number of drivers

Here is this

Sorry I'm actually second guessing myself here.. from the picture it looks like you would need 100k/3=33k so maybe a 50k potentiameter. I could be wrong though

yes that's what info im getting from other sources

im told 100K is for one driver, 50K for 2, 33K for 3

Yep that's what I read too. Sorry for the wrong info at first. This shot is pretty confusing. I'm just getting a grasp on all of it
