SP1848-27145 SA TEC1-27145 SP1848 40x40mm Semiconductor Thermoelectric Heatsink Cooler Peltier Plate Cooling side is the side printed with SP1848-27145, another side is the heat absorption side. It can generate electricity when there is enough temperature difference, it can increase voltage in series and increase current in parallel. This power generation plate is a low temperature, residual temperature, temperature difference, power generation, cost-effective, relatively stable performance. Description:

SP1848-27145 parameters references:
Temperature difference 20 degrees: open circuit voltage 0.97V, power generation current: 225MA
Temperature difference 40 degrees: open circuit voltage 1.8V, power generation current: 368MA
Temperature difference 60 degrees: open circuit voltage 2.4V, power generation current: 469MA
Temperature difference 80 degrees: open circuit voltage 3.6V, power generation current: 558MA
Temperature difference 100 degrees: open circuit voltage 4.8V, power generation current: 669MA
Note:
1. The above values are for reference only. In actual use, the wiring and booster plate, current may be lost and become different.
2. This product is in one and with a ceramic body, so its heat transfer is very fast, and the temperature difference between the two sides of the cold and hot needs to be studied and controlled when working.
