PSU Requirements for TECs

cougem · 05-18-2004, 04:52 PM

Hi I'm hoping to purchasr the Meanwell S-320 which has been recommended for the 226W TEC I'm hoping to get for my processor. According to http://www.dangerden.com/mall/Pelts/peltiers.asp the 226W pelt has an Imax of 24A, Qmax of 226.1, Vmax of 15.2V.

The thing is, would I also be able to run the smaller 80W pelt that comes with the Maze 4-1 off the Meanwell as well? The 80W pelt has an IMax of 8 and a Vmax of 16.1.

I really don't know what to analyse when I'm seeing if a PSU is sufficient. I know I'm asking for so much help here, but I'm so lost :shrug:

If anyone can help I really would appreciate it,

Thanks

EDIT: Oh and does anyone know how loud this PSU is?

did you ask the vendor ?

16.2*8=129W
15.2*24=364.8W

364+129=493W...can that Meanwell supply that kind of output...constantly?

That would be the power consumption if both TEC's were running ideal voltages and current. The TECs' power consumption won't be exactly like that, as those values are computed using set tems for the hot and cold sides of the TEC, and they will be different in your system. Although since they both have such close voltages, that ideal will be close to the values listed above.

One thing to remember however is that is also going to be a heat addition into your cooling loop. You could end up having to dissipate over ~700W of heat out of your radiator(s). Thats a ton of heat! Not mention a noticeable spike in the power bill.
