DiMeo have a problem , the Arduino with your code for marine works well the problem is that my sources are dimmable 0-10v are Inventronics , apparently when 0V are not entirely off .

So as I find the solution I was thinking DiMeo ring portion of the tip 141 and put my question now is whether these tip consume energy when LEDs are off . ??????
a greeting.

Hi!

Welcome José!

The consume should be 0 when the PWM is 0.

I think better use this circuit.

Best regards.

Do not quite understand what you say fernando , you say that you put transistor to the source to dimear ??
And so it goes at all?
As you see in the source plate puts 14-54vdc why I say that let current flow to a minimum.
I do not understand is that these sources the screens used for aquariums and do not know how .

As you can see in description the dimming isn't 0 - 100%.

Wattage: 42W
Max output voltage: 28-56v
Input voltage range: 90 - 305 VAC, 47 to 63 Hz
Input current: 0.48 A @ 110 VAC, 0.23 A @ 220 VAC
Inrush current: 60A at 230VAC 25ºC Cold Start
Dimmable: 0-10v
Dimming range: 10-100%
Spec: EUC-042SxxxDS


The TIP and IRLZ are MOSFET's to control the voltage/current. Of this way the dimming will be 0 - 100%.

I don't know how are you using the TIP but, I think better use the IRLZ.

Follow my schematic.

Best regards.

He was not wearing tip .
What I did was a plate with LM324 to amplify the 5V to 10V and then put the green cabre from source to gnd , the purple of the PWM source and yellow font did not put him in any way because these sources and carry 10v is the yellow cable.
So is the scheme that I got to amplify the output of the Arduino 5v .
and when I tried it seemed that if it worked but do not go out at all.

And probe sources without the Arduino with a simple potentiometer and has got it off to a minimum not understand why they are not dimmable , or is it that I need to put something as you say .

Well you say to see if I can do something and many thanks for answering so fast .
