0-10v PWM Dimming?

Hey RIU,

Been looking around for a couple dimmers for some leds, im currently trying to dim a MeanWell XLG-240-H-AB,

This driver is a 3-in-1 dimming driver that will allow 0-10v - PWM/POT/RESISTOR.

I have found a cheap PWM Dimmer online : https://www.ebay.com.au/itm/DC-12V-8A-LED-Light-Protect-Strip-Dimmer-Adjustable-Brightness-Controller-KC/312686664643

and was wondering would this work?

or would I need something different as im looking over the datasheet for the dimmer and it shows these specifications :

Specifications:
Material: Plastic
Max. Load Power: Output:12 V,96W -24V, 192W (8A)
Type: 12V-24V 8A Dimmer
Input : 12V-24V
Output: 1 Channel 96W 12V-24V (0-8A )
Static power consumption: 1W
Size: Approx. 88 x 60 x 56mm(3.5 x 2.4 x 2.2 inch)
Color: Beige
Working Temperature: -20~60℃

which leads me to think that this dimmer is meant to be installed in series with the leds on the circuit as opposed to being connected to the dimming leads of the driver (as it states a power output of 192w at 8A)?

I also found an almost identical clone to this dimmer on Arrow.com over here for reference :

PWM Dimmer : https://www.arrow.com/en/products/zdm-01/jkl-components

Data-Sheet : https://static6.arrow.com/aropdfconversion/29f3b3b3affba375c804482df0edcbed9e5bcf7e/2zdm-01.pdf

Which states that this particular dimmer from Arrow.com is designed for leds, and says in the datasheet that you can operate it on 5v-6v-12v-24v VDC.

im really confused if this type of dimmer will work?

totally understand where you are coming from, I am trying to find out how to make or buy a controller for Led that will have sunrise and sunset features. It has been a confusing couple of days, but so far it is looking like Adrinuo or something in the aquarium control area.

Those type dimmers would more than likely fry the meanwell driver. You can hook 100k potentiometer to the driver for dimming that is the easiest way. PWM is a bit more involved but can be done but it will take a PWM module and a 10 volt DC power supply. There is a whole thread on dimming in here might want to check it out https://www.rollitup.org/t/meanwell-led-drivers-3-in-1-dimming-function.838760/

That dimmer device wont work with your LED driver. This $6 dimmer potentiometer will do the job.

if you only want to dim a few meanwell B type drivers, go with a pot.
For one driver, simply a 100K (like linked above as complete unit) , take care that it really have 100K or add a 10K or whatever resistor in line.
The meanwells internal logic will sense the 100k pot resistance and do its own pwm accordingly, otherwise it wont be able to dim down to 0% anyway.

I am searching for options on led light controllers. The "best" one I have found so far is the chilled light controller. Has sunrise and sunset but is $299.00. I guess I'll use all the savings from buying strips on the controller.

$4 100k ohm pot from ebay will do the trick, buy a couple.

Great thanks! I was looking at a few different types of those 100k ohm pots and they seem to have different "Wattage Ratings"?

should I be taking this into consideration when buying a pot?

for example this pot from arrow is 0.2W - https://www.arrow.com/en/products/pc16sh-07cp20-103a2020-ta/amphenol

and this one is 0.1W - https://www.arrow.com/en/products/1831/adafruit-industries

Am I correct to Assume these Wattage ratings are the power draw that is being used by the Pot to do its job?

wattage dont matter, there is no load on them.
If only buying some pots, i would go with ebay 100K b type linear, buy 10 meassure them take one who is above 100K.

okay, how would I measure them? and would one of those pots listed from Arrow.com be good enough? I was going to buy 10 of them to add to existing fixtures that I have aswell. (wanting to buy from arrow because I need to buy a driver from there aswell and there shipping is extremely fast compared to fleabay)

yes both will do.
You need a multimeter for resistance.
Only problem, these pots eeldon reach 100k, you want them to reach 100k to have full power.
So you need to buy more cheap pots, or add a resistor in line

i never where able to go above the 100%.
The highest resistance you can have is open cable, no pot, thats 100%.
I testet with a power meter, was the same, 105K to open cable.
But just tested once with one driver, dunno.

Okay thanks mate, I was basing my observation on the A type drivers where you can turn them up and get 260-280 watts from a 240w driver. (Essentially overpowering it by 10-15%.

One more question arises, what would be a better option then these pots in terms of getting something that will work at 100% power without having to sort through a "silicone lottery" to find one with the correct dimming capabilities? I just think it's a tad wasteful to buy all these extras to find a good one, iknow they are cheap but is there something that is more reliable?

missed that youre using a XLG
for the pwm, pot dimming there is no above 100% but if its a A/B type you can overdrive by the onboard screws, like youll do with a A type.
So first set your screws, then use the pot.

To my view not really, you can buy pots with higher precision 10% 5 % but to my tests, theyre even worse, never reaching 100.
I simply have some resitors, 10K, 2.xK etc and put them in line.
Take 15k and you should be fine.
You cant dim to 0 then anymore, thats clear.
