TEC1-12715 Thermoelectric Cooler Peltier Module 40x40mm 12V 15A 142W High Power Semiconductor Cooling Plate

The TEC1-12715 supplied is a high-power solid-state thermoelectric Peltier cooling module that uses the Peltier effect to create cold/hot sides with DC 12V input, built with bismuth telluride semiconductors and 40×40mm ceramic plates for compact, silent cooling without compressors or moving parts.

It acts as a mini heat pump: supplying DC power shifts heat from one ceramic surface to the opposite side. Reverse current switches cooling to heating. Unlike low-wattage TEC models, this 15A variant delivers industry-leading 136W max cooling power for heavy-duty DIY, lab, and compact refrigeration builds.
