Thermoelectric SP1848 Peltier Cooler / Generator up to 4.8V 660mA

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.

Specification :

• Model: SP1848-27145
• 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

• 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.
