Description: Dimension: 40 * 40 * 3.8 mm / 1.57x1.57x0.15inch Wire specifications: 100 + / - 5 mm long RV lead wire single head 5 mm tin plating Internal resistance value: 2.4 ~ 2.7 ? (23 + / - 1 ?, environment temperature 1 KHZ Ac test) The largest temperature difference: delta Tmax (Qc = 0) more than 61 ?. Working current: Imax = 5 (rated voltage startup) Specification: Rated voltage: DC12V (Vmax: 15.5 V) The refrigeration power: Qcmax 45 w The assembly pressure: 85 n/cm2 Working conditions: temperature range and 55 ? ~ 83 ? (high environmental temperature will directly affect the cooling efficiency) Encapsulation process: standard around 704 silicone rubber seal Packing: bubble box packing, storing conditions - 10 ? to 40 ? ambient temperature Storage conditions: - 40 ~ 60 ? Package Includes: 1 Piece of Thermoelectric Cooler Cooling Peltier Plate Module Note: The word side is the cooling side wordless side is the cooling surface must be installed in the cooling surface radiator, or water cooling device, otherwise it will be burnt out. Whether it is water-cooled or air-cooled, it should be coated with thermal grease. When power is applied during the test without cooling, the cooling effect will be achieved. You should immediately unplug the power within 1 second, otherwise it will be easily burnt out
