A24 wiring circuit diagram

[kiloptero]

Hi, I am interested in making a panel similar to this one. https://www.kincony.com/32ch-smart-distr...stant.html . I need 2 breakers to be 32 Ampers. I only found 24v models.
How could I have a mix of 12v and 24v Ac connectors at the same time? I also see this excellent video https://www.youtube.com/watch?v=FE5fSduc0uI&t=597s . I only see 1 12v power supply. If someone could guide me. Great
