Dimable LED Driver
 
Need help finding a LED driver's Brands. Right now I have an Inventronics dimable LED driver. But when I dim it down to zero and there are still some percent of lights going through. Wonder if there any other brands have a zero percent of light going through when I dim it to zero.

Thanks for your help.

i have meanwell drivers and its the same as yours.

What are you using to dim them with? Which Meanwell do you have Troni? Many drivers require a hard power cut once they get down to 5%...if you use a controller, then this is very do-able...if not, it gets harder.

Potentiometer for manual dimming.
DA ALC controller.
I don't think it can goes down to 5%.

I have 2 Meanwells dimmed manually by a pot that go completely off. No visible light. I have the inventronics that dims but has to turned off via a controller outlet. I would have thought the other Meanwell would be the same.

Do you know which model you are using?

The model is ELN-60-48D picked them up from modularled. I wonder if the P version goes off completely.

Hi Troni, which model is yours?

Meanwell drivers like ELN-60-48D are capable of dimming to zero provided the controller can go to zero. If using a potentiometer it should go all the way to zero.

However Inventronics can only go to around 10-14% depending on the model. That is if you supply zero volts on the dimming line you will still get 10-14% on the LEDs.

For inventronics most people will dim all the way to zero using a controller then have the drivers switch off either using a Profilux EVG card or Apex Energy Bar.

i have meanwell 60-48D, using a potentiometer and when i dim it all the way down you can still see that the led has current flowing through it.
