View Full Version : Diy led dimming with apex (or any 0-10v source)

I know the limitation of lights per "string" fall back to the driver, but how many strings can be dimmed per channel?

Let's say I want 48 royal blue leds for example, I will need 4 LDD drivers, but can all 4 drivers/led strings be dimmed via a single variable port on the apex?

Yes. You could control dozens of LDD-H from one channel, provided you've converted the 0 -10V signal from the APEX to an LDD-H friendly 5V PWM signal first.

I have been researching that and it seems you are the man to go to for that.

How does one go about purchasing those units?

I have one of O2's convertors on my system, works PERFECT with the Apex. Plus... his unit plugs in with a regular Cat5 connector on both ends. :D

Does it alot the PWM drivers to dim down to 0% instead of the normal 10% you get with 0-10v?

LOL- If I remember correctly Poseidon's got two of them. Maybe he'd be interested in selling his spare? I don't have any available right now, just sold the last one earlier today.:facepalm:

Yes, it sure does!

LOL! Yes, I did have 2, gave one to a friend. We are going to try and use it on a "black box" LED to see if we can DIY Apex control on it. :D
