The red wire is connected to the positive terminal and the black wire is connected to the negative terminal. When there is a difference in temperature, it can generate electricity.
The parameters of SP1848-27145 as a power generator are as follows:
Temperature difference 20 degrees: open circuit voltage 0.97 V, generation current: 225 mA
Temperature difference 40 degrees: open circuit voltage 1.8 V, generation current: 368 mA
Temperature difference 60 degrees: open circuit voltage 2.4 V, generation current: 469 mA
80 degree temperature difference: open circuit voltage 3.6V, generation current: 558mA
Temperature difference 100 degrees: open circuit voltage 4.8 V, generation current: 669 mA
The above values are for reference only. In actual use, there will be current loss due to wiring.
In practical applications, a series-parallel combination is often used to obtain higher output voltage and load current.
The marked side is close to the heat dissipation surface (cold end).
The unmarked side is on the heat absorption side (hot end).
