home automation - relay on psu for leds

Hey! I've been going through threads finding some interesting things, however still not finding enough info, I'm curious, according to you all is the setup below plausible?

I'm only curious about the psu being 15a and the relay handling it, I would use max 30-40watts with the leds, would this work or is it something I should just skip? I would prefer to turn on/off the entire psu (wirelessly through arduino and nrf24l01+) with the relay instead of each led strip individually through several relays. Thanks

The PSU is 15A on the secondary side.
The primary side, depending on the mains voltage in your country, is <1A.
Inrush (startup) current might be several amps, but probably ok for those relays.
Check if the relay module is made for mains power. Some are not.
Post a link if you’re not sure.

Hey!
I’m in europe, sweden, so 230v applies to me as far as the outlet/main voltage is concerned.
I have these:

but I also have one of these if you see the link:
8ch 5v relay

What would you say, a go or no-go for any of these?
Thanks!

Have a look if the 230volt contacts are far enough away from the low voltage parts on the circuit board. I think 8mm is the minimum distance. Leo..
