SP1848-27145 40*40mm 150 degree Peltier
The SP1848-27145 is a 40x40mm thermoelectric Peltier module ideal for energy harvesting and cooling applications. Operates efficiently with temperature differences up to 150°C. Generates power from heat or creates cooling when powered—great for science, DIY, and industrial uses.
The SP1848-27145 Thermoelectric Peltier Module is a high-efficiency device designed for both power generation and cooling applications. Measuring 40mm x 40mm, this compact module can withstand temperature differences of up to 150°C, making it suitable for energy harvesting from heat sources or for creating localized cooling zones when connected to a DC power supply.
In power generation mode, it converts a heat differential directly into electricity—ideal for converting waste heat into usable energy. In cooling mode, it functions like a heat pump, transferring heat from one side to the other when electric current is applied. This module is widely used in experimental setups, DIY projects, camping power systems, and industrial applications.
