Generate electrical energy. The only requirement is that each face of the device must be exposed to different temperatures; a "hot" side and a "cold" side. The greater the temperature difference, the more power generated. While all of our thermoelectric devices will generate power.
Size: 40mm x 40mm x 4mm
Side with the word is near to the cooling surface (cold side)
Side with No word is near to the endothermic side (hot side)
Red wire to positive and black wire to negative, as long as there is a temperature difference,it can generate electricity.
These devices must be used in conjunction with a heat sink to avoid burned
Hot Side Temp
Module Resistance (Ohms)
Temperature difference of 20 degrees: open circuit voltage 0.97V, power current: 225MA
Temperature difference of 40 degrees: open circuit voltage 1.8V, power current: 368MA
Temperature difference of 60 degrees: open circuit voltage 2.4V, power current: 469MA
Temperature difference of 80 degrees: open circuit voltage 3.6V, power current: 558MA
Temperature difference of 100 degrees: open circuit voltage 4.8V, power current: 669MA
This device is known as TEC, Thermoelectric Cooler, Thermoelectric Module, Peltier Junction, Peltier Plate
* Note: You should never use this device without sufficient thermal cooling (heatsink, fan etc). Operating the it without additional cooling for more than a few seconds will damage the device. Hobby Components cannot replace devices that have been damaged in this way.
