Thought I would post a little diagram i made today after wring up a Profilux EVG-AP-2F card to control a DIY LED fixture.
Profilux uses the expansion card to dim any 0-10V dimmable LED drivers such as Mean Wells (D version) or Inventronics.
Each card is capable of running 2 channels of drivers with up to 3 drivers per channel. So in essence you could have something like 3 white LED drivers and 3 blue LED drivers on the one EGV-AP-2F card. You can then use multiple cards for more drivers depending on how many free L ports you have on your Profilux.
There are 5 wire connection blocks on the board.
1. Power Cord
2. Driver Power Channel 1 - Power Input for Drivers on Channel 1
3. Driver Power Channel 2 - Power Input for Drivers on Channel 2
4. Connection To Profilux - A cable comes with the EVG card to connect it to an L port on your Profilux
5. Driver Dimming Block - This block is split in 2 right side is for dimming wires coming from drivers on channel 1 and left is channel 2.
