About Diitao 4PCS TEC1-12705 Semiconductor Refrigeration
TEC1-12705 Dimensions: 40x40x3.8mm Component log 127; Wire size: lead length 100±5mm RV standard wire single head 5mm Internal resistance: 2.4~2.7Ω (ambient temperature 23±1°C, 1kHZ Ac test) Maximum temperature difference: △Tmax (Qc=0) 61 °C or more. Working current: Imax=5 (when rated voltage starts) Rated voltage: DC12V (Vmax: 15.5V); Cooling power: Qcmax 45W; Assembly pressure: 85N/cm2; Working environment: Temperature range -55 °C ~ 83 °C Test method: Hold the sides of the cooling chip with one hand, and press the wires of the cooling chip against the poles of the battery with the other hand. The red wire is pressed on the positive electrode, and the black wire is pressed on the negative electrode. If one side is slightly cold and the other side is slightly warm, it means that the cooling plate can work normally. Tip: The working state is heating and cooling. When the cooling part begins to work, the hot surface must dissipate heat well. The heat sink cannot be powered on for more than 2 seconds. The power supply of the hot and cold exchange should be carried out when the hot and cold side is restored to room temperature, which is generally greater than 5 minutes, otherwise it may cause damage to the circuit and the ceramic plate.
