The above values are for reference\nonly. In actual use, the wiring and booster plate, current may be lost and\nbecome different. 2. This product is in one and with a ceramic body, so its\nheat transfer is very fast, and the temperature difference between the two\nsides of the cold and hot needs to be studied and controlled when working.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThe side with words is close to the cooling surface (cold end), the wordless side is close to the heating surface (hot end)\u003c\/li\u003e\n         \u003cli\u003eConnect the red wire to the positive pole and the black wire to the negative pole, which can generate electricity when there is a temperature difference\u003c\/li\u003e\n         \u003cli\u003eSP1848-27145 SA Operating temperature between -40C to 120C\u003c\/li\u003e\n         \u003cli\u003eTemperature difference electromotive force (a): \u0026gt;190V\/C, Conductivity (): 850~1250-1.cm-1, Thermal conductivity (K): 15~1610-3-W\/Ccm, Excellent value (Z): 2.5~3.010-3W\/C\u003c\/li\u003e\n         \u003cli\u003eWhen the thermal energy is discharged from the low temperature side through the thermoelectric power generation piece, part of the thermal energy flowing into the device does not exotherm, and becomes electric energy in the device, and outputs DC voltage and current.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Haldzemo","offers":[{"title":"SP1848-27145","offer_id":68251213627629,"sku":"B0HHN3QG84","price":108.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0324\/1050\/1164\/files\/B0HHN3QG84.jpg?v=1794311812","url":"https:\/\/leoforward.com\/products\/sp1848-27145-sa-semiconductor-thermoelectric-generator-peltier-2-pack-sp1848-27145","provider":"LeoForward AU","version":"1.0","type":"link"}
