Low voltage, sometimes

@pdhoogh

While MDAR’s advice certainly will solve the problem. He is the practical man.

Thanks, I’m rarely called practical, I’ll take that as a compliment

@pdhoogh

I’m more the scientist and would like to know what is the cause of the issue

Yes, knowing why is very important.

Also, though less likely, it may be extra work to get mains power to the remote cabinet.

I did make the wild assumption that the remote cabinet would have mains power, because it’s got Velbus hardware in to control local devices.

But you make a good point.

If… The local devices were all 12V and their supply had enough headroom, I would be tempted to power the Velbus modules from it too.

Similar if they were 24V, but I’d put a dropper in there too.

All that said, like everyone else, I am intrigued to know what’s causing the volt drop.

Thank you both,
I’m still trying to identify where the problem can come from… opening all glass panels to see if there is a bad connection…
I will try to solve the problem, and put a new PSU as a last resort… (I have 220V arriving in my remote cabinet)
Thank you!
