Mr. Microscope Posted November 18, 2010 Share Posted November 18, 2010 Hello All, I tried researching this a little first, but about a million unrelated hits come up when you search for driver or driver options. I'm sure this has probably been discussed before, but I'm interested in what's out there. Are there any drivers that can, say drive more than 6 LEDs, and are simply dimmable without an additional power supply? It'd be nice if there was something that gave you the option to either just hook the pot wires together and make it work on straight current, or hook up a pot directly to the wires without an added power source. I like the simplicity of BuckPucks, but they can only handle so much power and are considered somewhat unrealiable in durability. Meanwells are cool, but the added power supply is an additional cost and a PITA from a space and design standpoint. Also, they seem to be somewhat hard to get a hold of. So far, I've looked at Luxeon Xitaniums, but they're too expensive and require a 0-10v wall dimmer. I'm not sure if this one is powerful enough, and I'm not sure about how dimming is controlled, but here's something: http://www.newark.com/roal-electronics/rld...iver/dp/69R7347 $37 Let's try to keep it around $50 or less. Finally, does anyone know of any multichannel drivers out there that one could attach separate pots to? Probably a bit more expensive than $50, but worth it if there are any. I know there are some for RGB type setups, but I don't know it the power is out there that we need for our "3Watt" LEDs. Link to comment
doctaq Posted November 18, 2010 Share Posted November 18, 2010 there was talk of a new meanwell that created its own reference voltage but i forget the model numbers and such now Link to comment
jfarabaugh Posted November 18, 2010 Share Posted November 18, 2010 much more then 50$ especially once you add the dmx controller http://ledsupply.com/quadpuck.php Link to comment

I know there are some for RGB type setups, but I don't know it the power is out there that we need for our "3Watt" LEDs. FYI, Philips/Advance makes the Xitanium drivers. It's not under a Luxeon brand (both owned by Philips though) The Roal driver isn't going to be of much use with only 16v output (about 4 LEDs with 3.7v average forward voltage) Most of the multi channel drivers are DMX controlled, like the Quadpuck that jfarabaugh linked. Anything more powerful than that driver, and it gets spendy fast. There are alternatives to the Meanwell ELN drivers coming to market in the very near future that will simplify life. Link to comment

Thanks! There are alternatives to the Meanwell ELN drivers coming to market in the very near future that will simplify life. Really? Who makes them? Link to comment
Genj Posted November 18, 2010 Share Posted November 18, 2010 Really? Who makes them? I am thinking it's going to be someone near and dear to our hearts...and minds... Link to comment
redfishsc Posted November 18, 2010 Share Posted November 18, 2010 I am thinking it's going to be someone near and dear to our hearts...and minds... WOW!!! I didn't know Rush Limbaugh was an LED manufacturer! *runs like hell* Link to comment
Bill Nye Posted November 18, 2010 Share Posted November 18, 2010 WOW!!! I didn't know Rush Limbaugh was an LED manufacturer! He was obviously talking about Al Gore. This was his next project after inventing the internets. Link to comment
kgehrke Posted November 18, 2010 Share Posted November 18, 2010 The 4 channel dimmer combo on ledsupply costs just over $250 before you buy the LEDs, but it supports 4 channels with 12 on each channel. Link to comment
Hans Dorn Posted November 19, 2010 Share Posted November 19, 2010 If you're already using 4 drivers the extra effort for the dimming supply is minimal. You only need one for all 4 pots. I juist ordered a couple of these fom a german supplier. (The 700mA 32W version) I paid €25 a pop just to later find out that they're offered for $11 on alibaba Link to comment
doctaq Posted November 19, 2010 Share Posted November 19, 2010 why does that thing look crazy big Link to comment
Hans Dorn Posted November 19, 2010 Share Posted November 19, 2010 why does that thing look crazy big That would be the 60W version, good for 26 LEDs, and going for $18 in china... Link to comment

Good price, but it says minimum 50 order. How does dimming take place on that? Is it similar to the Meanwells where you can plug it directly into the wall without an additional power supply, but need an additional power supply for dimming? Or is it self regulated with the ability to hook up a pot directly to it? EDIT: oh, wait. I see it says, "Dimmer type: 0-10V." I'm guessing it's similar to the Meanwell. It'd be great if we could actually find them for $11 though. Link to comment
calvin415 Posted November 19, 2010 Share Posted November 19, 2010 Anyone know of a good source of knobs for the buck puck pots? Link to comment
Mr. Microscope Posted November 20, 2010 Author Share Posted November 20, 2010 Anyone know of a good source of knobs for the buck puck pots? I just google "potentiometer knob" in the shopping option. You'll get tons of cool hits. I like the gold ones. Just make sure that the inside diameter matches the pot you have. Link to comment
calvin415 Posted November 20, 2010 Share Posted November 20, 2010 Haven't order the buckpucks yet anyone know what size the pot is on it? Link to comment
redfishsc Posted November 20, 2010 Share Posted November 20, 2010 I look eagerly forward to the day when someone comes up with a plug-n-play 0-10v that behaves just like the RKL's ALC module---- a programmable gradual ramping of voltage for a nice dusk/dawn effect. Link to comment
Mr. Microscope Posted November 20, 2010 Author Share Posted November 20, 2010 Haven't order the buckpucks yet anyone know what size the pot is on it? I'm pretty sure the diameter is in the datasheet. http://www.ledsupply.com/03023-d-e-1000p.php Link to comment
doctaq Posted November 20, 2010 Share Posted November 20, 2010 its a 5k ohm and smaller than a penny Link to comment

No size listed. Anyone have one of these know the size? I see everyone with them, and have knobs, just want to be sure of the size... I've read 1/8" on some, but 1/8" knobs are tough to find, most are 6mm or 1/4"... Link to comment
redfishsc Posted November 21, 2010 Share Posted November 21, 2010 hmmmmm.... maybe I need to start making some sweet custom knobs from exotic hardwoods on my lathe :D in fact I have a few I need to make for my upcoming canopy. Link to comment
