[USER=9554]@arataisozaki[/USER] : this unit was built last year for an other build. I'm just borrowing it but I'll ask the permission to adapt it

I'm also working on a separate PCB to be able to control the Meanwell EPP-400-12 with your power switch.
For me, it's the most universal and cleanest way to use a MW.

Haven't been able to get it work though... $:\$

I wanted to test a Meanwell EPP-300-12 but, from the spec sheet, that PS_ON connector pinout of the EPP-300 is the exact opposite of the EPP-400.
Connectors are also different.

I hope it's just an errata from the spec sheet. Otherwise it's just a stupid design choice from MW.

Will have to confirm that with a multimeter.
