good place to get potentiometer for meanwell

[hybridcheef]

i need a 100k potentiometer but dont know whether i need a linear one or a logarithmic or whatever i dont know. can someone tell me and i linked a few in the next post sorry.

what about these ones? https://www.amazon.com/JIUWU-Guitar-Potentiometer-Replace-Electric/dp/B00RGKFMJG/ref=sr_1_3?ie=UTF8&qid=1493762075&sr=8-3&keywords=100k+potentiometer



do i want linear, lagorithmic?


these are pretty cool too, would these work?

and theres also these. linear

that dont answer my question, did you check my links? will those work for my meanwell 240-2100b driver?

any of those will work, but you get what you pay for. if you only need 1 spend $5 on a good one as opposed to $5 on 5 cheap ones

you want linear

The only thing worth saving on these are the knobs. Total junk. I replaced them with these....Linear Taper 1/2 watt 100K Ohm Potentiometers https://www.amazon.com/dp/B0002KRE2U/ref=cm_sw_r_cp_apap_JbpHKzTSpa94s. Added a 10k ohm resistor to the neg. side as per @gromau5. Gives dimming down to 10% with the resistor in place. No problems since I changed them out.

Got 5 for $5 on ebay. None go up to 100%, highest is ~90%. So if I understand correctly none of them are actually 100k. Someone in the thread I made about this recommended 125k to go to max.

Ya I bought a few bags of the 100K cheapies and they range from 88K-115K. I used the ones over 100K and 2 or 3 of them went bad over time. The bad ones caused my driver to reduce its output power to 50% and would flicker occasionally. At first I thought my drivers were bad but eventually I realized it was the pots, even though they tested fine on the bench.

Bourns makes good stuff I wonder how these would be.

Even if you have a pot that is over 100K you will get slightly more driver output when you disconnect the pot. You can install a switch to interrupt the pot for a small driver boost.
