tamthapluc Posted June 18, 2009 Share Posted June 18, 2009 So if i use the 0-10V output from ReefKeeper Elite to control the dimming on ELN-60, using the LM317 simple like this? Link to comment
evilc66 Posted June 18, 2009 Share Posted June 18, 2009 No need to use an LM317 for that. Link to comment
tamthapluc Posted June 18, 2009 Share Posted June 18, 2009 So you mean that the 0-10V output from RKE is PWM. Evil, sorry for bugging you all the time. I spent a whole week to read this thread and the other ultimate led guide but obviously i still wasn't able to decrypt it Link to comment

But it looks like the model P is the most popular here. Link to comment

I have tryied 9v dc adapter to power up ELN-60-27P before and it work too. May be the dim up/down not as smooth as PWM cct. Well i got it. It will work with the D model like ELN-60-48-D.

I spent a whole week to read this thread and the other ultimate led guide but obviously i still wasn't able to decrypt it Curious about how to hook up to the reefkeepers as well. I just bought the RKL and will buy the ALC if I can figure out how to hook it up to the 4 meanwells that my build requires. Link to comment
evilc66 Posted June 19, 2009 Share Posted June 19, 2009 RKL doesn't currently support the ACL unit. It's supposed to get a firmware update soon to add compatibility. The ELN-60-48P will require a slightly different setup to work with and 0-10v system. I have been looking into cicuit designs for voltage to frequency converters. Link to comment
chazde3 Posted June 19, 2009 Share Posted June 19, 2009 Not a problem that it doesn't support the ALC yet, because I don't have my LEDs or drivers yet. Let me know when you've found out how to do this. The sunrise/sunset effects that are potentially possible would be awesome to have. Link to comment

evilc66 Posted June 19, 2009 Share Posted June 19, 2009 At $99, it's extremely tempting. I may have found a super simple (even easier than the pwm generator) way to do a voltage to frequency converter. I'll build one up soon and test it. Link to comment
JoshG Posted June 19, 2009 Share Posted June 19, 2009 I just picked up a new RKL from the board for $90, I plan to purchase the ALC once it becomes compatible as well:) Evil, I ended up buying 3 ELN-60-48D drivers from Powergate, should be here soon. Do you know how the DIM+- would wire up to the ALC? Link to comment
McJosh13 Posted June 19, 2009 Share Posted June 19, 2009 Why is it that you need a voltage to frequency converter? I've been using a 0-10v signal from a LM317 to control my meanwells (ELN-60-27P) and it has been working out pretty well except for the fact that it doesn't dim down past 333ma/string. I believe that even with a pwm input signal you wouldn't be able to get full dimming because past 333ma you probably go below the forward voltage of the led. Link to comment

A pwm signal will work a lot better for you on that driver. A 0-10v input will offer some dimming, but I had noticed that it was not very linear and difficult to control. With the options for either the pwm circuit and the voltage to frequency circuit, anyone will be able to use either driver version with whatever setup they have. Link to comment
JoshG Posted June 19, 2009 Share Posted June 19, 2009 Not sure. Never seen an ALC up close. Here Evil, check it out, it's the user manual for the ALC. Would it be as simple as connecting the DIM+ wire from the driver to the red sig wire of the ALC 0v-10v connection? http://www.forum.digitalaquatics.com/downl...file.php?id=186 Link to comment
evilc66 Posted June 19, 2009 Share Posted June 19, 2009 DIM+ to the red wire and DIM- to the black. Simple enough. Link to comment

Just for clarification: So you still prefer convert 0-10v to pwn using with ELN-60 P model? Or I should i go with D model for less headache and still having same good control? Link to comment
evilc66 Posted June 20, 2009 Share Posted June 20, 2009 Both can work, but for simplicities sake, the "D" model will be a little easier. It will also depend on the cost and availability in your area. Link to comment
JoshG Posted June 20, 2009 Share Posted June 20, 2009 I seriously ordered these Tues and just got them today. $38.50 each Link to comment
deepdvnarq Posted June 20, 2009 Share Posted June 20, 2009 where did you order them from? i must have missed it from somewhere, but what is the difference of the "P" and the "d"? is the p a pwm and the d a analog/digital.....just guessing. Link to comment

Yes the D is the analog 0v-10v. I want to try and set them up using the RKL/ALC module. I ordered them from Powergate. Evil I read this on the DA forums about the ALC module, can you explain it? Will I still need to connect the 10V power supply to the drivers? "Just note that the ALC can not source any meaningful current. It's simply a voltage output for inputs like what you're talking about!" http://www.forum.digitalaquatics.com/viewt...?f=21&t=674 Link to comment

You do not want to hook up LEDs directly to the 0-10V output on the ACL. The Meanwells use a 0-10v low amp input just for a signal to tell what percent to increase the output to the LEDs. The soul purpose for the 0-10v output on the ALC is to hook up to a 0-10v dimmer input on a device like the Meanwell. Link to comment

evilc66 Posted July 15, 2009 Share Posted July 15, 2009 Could be interesting. Keep in mind that these will still require a specialized dimmer to get that to work, so thats more added cost. Link to comment

Dimming issue is the same either for ELN-60-48P or above mentioned LED driver..... Lets see what they cost..... Link to comment
