My project will consist of almost 100 PC fans, and I am going to control them using an Arduino. Now, I am trying to figure out how to supply enough external power safely and how to divide my circuit. Since it will deal with a lot of currents, I would like to check my plan with you guys before testing it to prevent me from being burned.
Here are the specifics, my plan, and questions. (I’ve also attracted a diagram of my circuit)
- Each fan consumes 12V and 0.14A. And all fans will be hooked up in parallel.
- I will use 2 adapters(12V, Max 10A) to safely draw currents from wall outlets.
- I will use solderless breadboards for my circuit. From what I found, solderless breadboards are recommended under 1A. So, I will make 20 groups of 5 fans for the safe power supply. (0.14*5 = 0.7A)
- As I use two adapters, one can support 10 groups (7A). Since the breadboards cannot handle 7A, the currents need to be divided before going to each breadboard. So, I am thinking about using terminal blocks distribution to divide current into 10, and I am not sure if I’m going the right way and find the right one.
Could you please look at the terminal block that I found? Will it work for my project? I’ll leave the picture below. And do you see any problems in my plan?
