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.
