High Temperature 40x40mm Peltier TEG Power Generator Module

Heating side is empty. Red wire connects to positive, black wire connects to negative. Generates electricity when a temperature difference is applied. Temperature difference vs. output: - 20°C: Open-circuit voltage 0.97 V, current 225 mA - 40°C: Open-circuit voltage 1.8 V, current 368 mA - 60°C: Open-circuit voltage 2.4 V, current 469 mA - 80°C: Open-circuit voltage 3.6 V, current 558 mA - 100°C: Open-circuit voltage 4.8 V, current 669 mA Note: These values are for reference only. Actual performance may vary depending on wiring, load, and use of a step-up board, which may introduce current loss.
