So for my heated bed im aiming for 330mm squared 500 watts 12v does this sound about right?

You could go AC with SSR

What are you’re suggestions for an SSR and heated bed specs.

Also the SSR would hook up directly to mains ac power and then be converted to DC or not? Before being sent to the bed

The board’s output triggers the ssr on and off. The power stays ac and the heater needs to be AC check Ali rubber. @Eclsnowman ​ what specs are you using?

Omeron G3NA-220B SSR. Heated bed running at 120v AC (don’t fear the AC, you don’t fear your vacuum cleaner, that’s 120v and you handle that on a cord)

@Eclsnowman I will ground my buildplate. I mean…the bed is a cheap one from china :wink:

Thanks so much!
