PCB for Mean well ELN and non-dimmable drivers

[Fernando Garcia]

This circuit allows PWM (0 - 5V) control for drivers analog, PWM (0 - 10 V) or non-dimmable.

Also allows use a power supply (e.g. 12 - 48 V) directly connected to LEDs but, without current control.

The schematic:

PS. Yes, I know that the pull down is acting as voltage divider but it's no so bad in this case since the voltage on gate could be 4.95 V with an input of 5 V.

With this project you can buy the PCB and build your own board.

You can see the gerber files using the Gerbv.

To open the files go to File / Open layer(s) and select the gerber files.

You can buy the PCB from Itead Studio by example.
