I have built a simple automatic switch that synchronizes IKEA LED strip with the main light in the room, eliminating the need to switch multiple switches in the evening.
Currently it works like this:
It's a bit simplified but that's the gist of it. Now the relay is a bit noisy, it's a high power relay soldered within an Arduino module that I bought along with the driving circuit.
I have a smaller relay that I could use but if I do, I need a mosfet to switch that relay. And the mosfet I have is rated for up to 60V and 50A continuous current. That's way more than the LEDs use.
So my question is, is it safe to replace the relay and the relay driver with a 2SK2049 mosfet. And if it is, how to connect it properly?
