TEC1-12715 Peltier cooler module

  • $4.90

TEC1-12715 vs TEC1-12705, TEC1-12706

The 127-15 (127 interface, 15 amps) is a workhorse. It features thinner alumina plates (better thermal conductivity) than the more common TEC1-12705 and 12706, fatter wires, and can be run at up to 200 watts with sufficient cooling. Recommend running at 100 watts per module or below for excellent performance and longevity. While you can push a 12705 to 80 watts or more, all you'll get is heat. The 12715 is happy at 100-180 watts with appropriate cooling.

When the ambient temperature raises or falls 1°C, the module resistance will raise or fall 0.015 accordingly. 

You can always run these at lower voltages for higher efficiency - as the current decreases, the coefficient of performance increases. At 12 volts the ΔT is almost 60°C. As you decrease the voltage and current draw, ΔT will decrease, but even at 1 volt there is a noticeable temperature difference, accompanied by the most efficient heat pumping you will find for this price.

Take your temperature control needs to a new level with solid-state.
