this video was very confusing, even for a group of guys with a combined 50 years LV experience. Guess we have more learning to do. Im surprised he didn't link the dm10x he was talking about.. I can't find it online.
@nonameter_Lighting If the LED driver is providing the 10VDC with a positive and negative (Purple & Pink) to the "dimmer", how is it reading a change in the 10VDC? What's going on in the dimmer that would change the voltage? Or am I looking at this in the wrong way. 10VDC is coming from the driver on the pink which is powering the dimmer, which then sends the adjusted return voltage on the Purple? In any case, how is the voltage changing?
@@r055f1991That only answers half the question. If the dimmer is simply a resistor, no matter how big the resistance is, the voltage across that resistance is always going to be 10V.
I can think of two possible ways to detect what the controller does in that case, if the controller is a simple variable resistor. - By increasing the resistance, the current that will flow back to the driver will decrease.. The driver could measure that. - The driver output is 10 Volt but has an (internal) output resistor of 10k (for example) Then if you change the resistance of the controller to 10k, the output of the driver (at its terminal) is only 5 V. Each of the resistors (both 10k in my example) drops 5V. I don't know what happens inside your specific driver.

Great video! That answered alot of questions in under 5 min.
Could you explain this again with oranges and apples?
But what there is inside the sincing dimmers? Could be used 0-100 K ohm potentiometr?

Slide dimmer gonna resist

that was plain english?
Yeah..
huh?
