Feature:1. Can work continuously without any refrigerant, there is no pollution source or rotating parts, no rotation effect, no sliding part. A solid piece without vibration, noise, possess long life and easy installation2. Semiconductor refrigeration film possess two functions of both cooling and heating3. A currenttransducer type chip. Highaccuracy temperature control can be realized through the control of the input current. It is easy to realize remote control, program control, and computer control to form an automatic control system when coupled with temperature detection and control means4. The cooling and heating time is very fast, the thermal inertia of the semiconductor cooling fin is very small, the cooling fin will reach the maximum temperature difference in less than one minute when the hot end has good heat dissipation and the cold end is empty5. Semiconductor refrigeration fins are generally used for power generation in the middle and low temperature areas. Reverse use of semiconductor refrigeration fins is thermoelectric power generationSpecification:Item Type: Thermoelectric Cooler ModuleModel: TEC1-12715Material: Ceramic + semiconductorPurpose: CoolingWire Specification: Wire Length: Approx. 100mm / 3.9in 5mm, RV standard wire, single head approx. 5mm / 0.2in with tin platedInternal Resistance: 2.4~2.7 (ambient temperature 231, 1kHZ Ac test)Dimension: Approx. 40 x 40 x 3.3mm / 1.6 x 1.6 x 0.1inMaximum Temperature Difference: Tmaximum(Qc=0)>61Working Current: Imaximum=15A (when the rated voltage starts)Rated Voltage: DC12V (Vmaximum: 15.4V)Cooling Power: Qcmaximum 150WAssembly Pressure: 85N/cmWorking Environment: Temperature range -6567 (too high ambient temperature will directly affect the cooling efficiency)Ambient Temperature: -1040How to Use: 1. The working state of the refrigeration sheet is that one side is cooling and the other is heating.2. To the left of the red line, the upper side is the hot side, and the lower side is the cold side..Package List:1 x Thermoelectric Cooler Module
