Its 7W a pad for the small ones and big ones I believe

I think per pad, i have no clue tho

242

If you confirmed you built it right….

Then you KNOW the only issue is you are not providing the required Electrickery for the herd of heat mats you’ve attached.

So its the AC/DC and heat pads, i will need either less heat pads or a stronger AC/DC?

Im just confused as to what all that means is all. Im re reading everything over

246

The first thing we did is run through the entire setup and identify any potential errors. Identified two points, corrected them, and moved onto heating element.

@CapitalismSucks420 tested the heating element at wall power to identify wiring issues of heating pads.

After said problems were corrected, PID and SSR function correctly- the heat pads turn on and off when the PID/SSR tell it to.

Not enough power!!!

7W times 6 heat pads to tell how many watts yes?

248

Nope.

You said you had 4 12W and two 7W

Yes that’s what I’m trying to say. Just bad at explaining.

I had a few things that were tapped wrong so i reconnected those, plugged the pads into the wall and rewired them onto the AC/DC properly as before I just had them all tied into one

I messed up on my specs, the smaller ones have 7W bigger ones are 7W

So in total I have 6, 4 small and 2 big and all have 7W

3.5 amps for 7W

6x12 = 72
6amps

Is that correct or no

255

Yep. The bane of my existence…

Sorry boss, we d’ nay have the power!

So i need a 10amp ac/dc?

257

Yep. You’ve got it.

If you’ve got six 7W heaters you need at least 3.5A of power supply to make them go.

And at 12V a 12W heater does draw 1A

(So six WILL draw 6A).

Need is a strong word. Especially if you’re actually running six 7W heaters.

But going large isn’t a bad thing here.

Will this work

I think it will work. Going to buy something similar at work today

I also figured out future issues now.

Learned a good amount about this so far, going to write good majority of this down tonight
