LED buckpuck vs drivers

I think so. The problem is that the unregulated ones can go up to 15 volt IIRC which might damage the meanwells. To check measure the voltage with nothing attached. If is near 10 volt your good if it is over 10.5 volts I would keep looking.
 
OK, isn't it rare to find a 10v one? Most are 12? I could just buy one off eBay or elsewhere, if anyone has a link. And it doesn't matter what pot I get, there all the same?
 
OK so I need a 10v wall wart regardless. Do you know or have a link to a better one?

BTW I've been looking at all the plugs (wallwarts) on any electrical device I see and if I find a 10v one, the amperages are all different? What should I be looking for? I'd feel more comfortable just buying the correct wallwart if there is such a place that sells them? Don't want to burn my house down. Thanks.
 
The meanwells don't draw a lot of current. So 100-200 ma is probably fine. Can't remember how many driver you have, but about that range. I have not heard of any good source for sure. Two that were mentioned were for recharging the swifter and one from a guitar store, but I don't remember if either was regulated. You can check this out (sorry no specs online)

A little more power than you need but, it might run a cooling fan to.
 
I'm running 3 ELN-60-48D drivers. So .2 A 10v wallwart,hmmm that's going to take some searching.
What fans/power source is best to run? Same 10v .2 A but I guess it depends on the fan? My LEDs will be in a canopy so I'll provably just buy a prefabbed unit.

Where can I find a better pot then the radioshack one?
 
I don't think that is a bad one. Mouse, digikey, future may have a better one, but I don't think it is worth the additional shipping charges.

A larger current won't hurt, but will cost more.
 
OK so I'll just stick with the radio shack pots and find a 10v .2A wallwart for each meanwell. Then I'll need to find some sort of fan/powersource.
 
That power supply will work for those fans. However if you find a 10v supply with 300ma or more it will also power those fans (upto 2). For each fan add 90 ma (maybe a little more to be safe) to the power supply you are looking for. Bigger is fine it won't be as efficient (I think) when supplying less power.
 
How would a 12v 500ma supply only power one fan yet a 10v 300ma supply 2? It that What I should look for? This is What I don't understand, What takes What volts or amps, why,How, etc etc.
 
IIRC the fan was 8-14 volts and had a current of .090 amps. So the 12V supply could handle 500 / 90 or 5 fans. The 300 ma could handle 300 / 90 or 3. These are ideal you probably want 10-20% extra power available. So in these cases I would probably drive one less than the equation says (I know they are right at 10% leftover).
 
What's IIRC mean? So if I get the 12v 500ma supply I should run 4 fans? I don't mind running 2-3 fans but 4-5 is a bit much, maybe over my 6ft tank but not nano. Guess I should find a 10-12v 300ma supply then. So just make sure your voltage is in the range of the thing your powering and the amperage doesn't exceed the supply? So why do I need a 10v supply for the pot if I can use a 10-12 for fans?
 
If I Remeber Correctly. If you get a 500ma supply you CAN run 4 fans. You CAN run 1. Anywhere from 0 to 4 would be fine. 6 maybe. 6 and you might fry the power supply.

The issue is that a power supply as some inefficiency. The larger supply will have more. So if you get a 10 volt 1000 amp supply it will work. BUT you will use a lot more electricity then a 10 volt at 500 ma even though they might be only supplying 100ma. This is seen in your electric bill. Is this any clearer now?

Correct everything with the same voltage can go on the same power supply and the current will add up. They can not add up to be larger than the supply can produce.

The meanwell only allow for a dimming input to 10.5 volts - you don't want to go over that. Fans are a lot more tolerant.
 
OK, so basically more power, more fluctuations. So since these fans go from 8-14v I believe and 90ma I can run that 12v 500ma supply. makes sense. So I have to do some searching, find a better power supply, something more accurate in the range I am looking for. For the pots, I want 10v but what's the ma? Thanks for all your help and patience answering my questions, I greatly appreciate it.
 
Not more fluctuations, more electricity ($) to run a larger supply.
Any milliamps will work over about 50. The larger that are supplied (or can be) the more electricity you will use even though whatever ower supply you pick will supply the same amount of power. Power supplies are most efficient near (70-80%) of their rate power I believe. So since you probably won't find a 50 ma supply look for something around 300 and plan to run your fans off of it.
 
OK, I got the fans down. What about the pot? They need 10v but what ma? Need to figure out the power supply for the pots. Also what are the size of the stars? I'm trying to figure out what size heat sink for 37 LEDs. I'm hoping to get away with a 12x12 and 1-2 fans.
