I've been trying to build a small cooler using 2 stacked peltier devices, as per Youtube video.
Attached is a diagram of the setup. Results have been poor at best. After several attempts, it seems the TEC-12715 module goes open circuit. (as measured on meter is diode mode)
The TEC-12706 is rated at 15.4v 6A max, and the TEC-12715 is rated at 15v 15A max. I'm using an old 250w ATX power supply which is rated at
12v 9A and 5v 25A.
The TEC-12715 is connected through a temp controlled module(W1209) , whose output relay is rated at 14v 10A. The TEC-12706 is connected
directly to the 5v ATX rail.
Why the TEC-12715 blows, and the TEC-12706 doesn't is confusing at best.
