Note:
The experimental data in this group uses a matching resistance of 4.21 ohms to achieve maximum output power. The side with words is cooling, and the side without words is heat dissipation.
SP1848-27145 parameters are as follows:
Temperature difference of 20 degrees: open circuit voltage 0.97V, generating current: 225MA Temperature difference of 40 degrees: open circuit voltage 1.8V, generating current: 368MA Temperature difference of 60 degrees: open circuit voltage 2.4V, generating current: 469MA Temperature difference of 80 degrees: open circuit voltage 3.6V, generating current: 558MA Temperature difference of 100 degrees: open circuit voltage 4.8V, generating current: 669MA The above values are for reference only. There will be loss of current when wiring and booster board in actual use. Because this product is one piece and a ceramic body, it transfers heat very quickly. The temperature difference between the cold and hot ends needs to be studied and controlled.
