Dimable LED Driver

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.

Whose right and whose wrong

I have 8 inventronics drivers on my lights and they will not dim to complete zero ( as in OFF ) unless the power is cut to the driver by my controller. The best solution for your situation Kevin is to have a timer to turn off the power to the driver.
