kidrobot Posted October 7, 2009 Share Posted October 7, 2009 hi evil i know your busy, but any updates on the circuit for the ALC? thanks Link to comment
deepdvnarq Posted October 7, 2009 Share Posted October 7, 2009 what's up with the manual 555/556 timer! just joking i know you will get to it eventually Link to comment
evilc66 Posted October 7, 2009 Share Posted October 7, 2009 hi evil i know your busy, but any updates on the circuit for the ALC? thanks I have been thinking more about this (now that I have an RKE, w00t!), but haven't gotten any further on a circuit. It's not hard, but it's finding the time. what's up with the manual 555/556 timer! just joking i know you will get to it eventually I'll get it done, I promise. I'd say I'd do it this weekend, but I'm helping install my carpet (still doing storm/insurance repairs ) Link to comment
jasonbarber Posted October 7, 2009 Share Posted October 7, 2009 Lots of different manufacturers offer led power supplies these days. Meanwell seems to be a low end manufacturer, similar to Altech. If you are willing to spend some more money on better quality products go with Sola or ABB. http://www.clrwtr.com/Power-Supplies.html Link to comment
evilc66 Posted October 7, 2009 Share Posted October 7, 2009 Different strokes for different folks. Those are regulated constant voltage supplies though. These are specifically LED constant current drivers. Completely different animal. Anyway, while a nice DIN rail power supply is great, 90% of us can't afford one as they would be almost equivalent in cost to our entire LED array. Link to comment

kidrobot Posted October 16, 2009 Share Posted October 16, 2009 Bump for the ALC circuit hey did u try hooking up the ALC to the drivers? did it work? Link to comment
sialkoti Posted October 16, 2009 Share Posted October 16, 2009 hey did u try hooking up the ALC to the drivers? did it work? Patient is virture buddy, these things does take times ...... Link to comment
kidrobot Posted October 16, 2009 Share Posted October 16, 2009 Patient is virture buddy, these things does take times ...... i know i just wanted to know if anybody tried it without the circuit... Link to comment
not_sponsored Posted October 16, 2009 Share Posted October 16, 2009 I tried it with the buck pucks but my RKL-ALC is not working correctly, I have it set to 50% intensity but it ramps up to 10V regardless of the intensity I set and I burnt out one of my pucks. Gonna try and switch to meanwells, would be nice to use this damn ALC that's been sitting around for almost a year. Link to comment
evilc66 Posted October 17, 2009 Share Posted October 17, 2009 Oh, dude. You can't just hook it up like that. It's no surprise you killed a Buckpuck. You need to use a voltage divider before the Buckpuck to drop the voltage. I though I had posted this somewhere before, but here it is again. ALC+ | 100K | |---Buckpuck | 100K |ALC- Use 100K ohm 1/4W resistors. Link to comment

evilc66 Posted October 19, 2009 Share Posted October 19, 2009 Depends on how the ALC does the 0-10v. If it's a true analog output, your assumption would have been correct. If it's a 10v pwm (more likely), then you would have cooked it at any level. I'll have to find out how DA does it. Link to comment
disbjohn Posted October 19, 2009 Share Posted October 19, 2009 would there be any issues running 12 LED's, 6 CW and 6 RB on one ELN-60-48D ? Link to comment

If it's a 10v pwm (more likely), then you would have cooked it at any level. I'll have to find out how DA does it. I was hoping the serial port was pwm and the 0-10vdc ports were true analog, please let us know when you get a chance, I am really wanting one of these for my ELN-60-48Ds. Thanks Link to comment
evilc66 Posted October 20, 2009 Share Posted October 20, 2009 A tech at DA said that the 0-10v outputs are true analog. I'm not 100% sure I believe them. I'll pass final judgement when I get my hands on my own and hook it up to my scope. Link to comment
deepdvnarq Posted October 21, 2009 Share Posted October 21, 2009 so i just read the last few pages again but i seem to have confused myself some. i have the "p" drivers and i just recieved the ALC. is there a circuit that goes inbetween the "p" model and the ALC or i'm i better off getting the "d" model for the ALC. i know Opy01 has the "d" models and his is working (without dimming for now) with the ALC. just incase i have 4 "d" models on the way.

deepdvnarq Posted October 21, 2009 Share Posted October 21, 2009 hey D. did you get all 4 of the d's for 20 bucks? yep sure did! if you don't beieve me...ask my wife! Link to comment
Aussie_00 Posted October 21, 2009 Share Posted October 21, 2009 There has been some work here on Arduino platforms, but because it is a relatively simple platform to program for, the sky is the limit. Go nuts, try it yourself. If you are going to use a Meanwell "P" with an Arduino, you need to control the driver via a transistor feeding it 10v. The outputs of the Arduino are only 5v. Keep in mind I am not to savy with electronics and have been picking things up as I mess around with my Arduino but.... Based on what you're saying... would the diagram attached would work running a P on the Arduino. The DIM+ and DIM - would simply replace the Load RL. So I would need a 10v power supply, Transistor, and Resistor? Link to comment
evilc66 Posted October 22, 2009 Share Posted October 22, 2009 Pretty much. You can even get self biased transistors and can skip the bias resistor between the micro and the transistor. Link to comment
Margrave Posted October 23, 2009 Share Posted October 23, 2009 I was planning on trying to adapt this fan-control circuit, but this looks just a little bit simpler . Could either of you (Aussie or evil) recommend a part number for the transistor? -Margrave Link to comment
evilc66 Posted October 23, 2009 Share Posted October 23, 2009 Most any NPN transistor will work. Doesn't have to be anything fancy. Link to comment
