Uxcell Tec1-12703 Thermoelectric Cooler Heat Sink Cooling 12 Volt 18 Watt Product Details Specifications: Model: TEC1-12703 Voltage: 12V Umax (V): 15.5V Max Current (A): 3A Cooling Power: Qcmax 18W Resistance: 4.0-4.3? ?Tmax(Qc=0): up to 60C Operates Temperature: -55C to 83C Power Cord: 29cm Dimensions : 40mm x 40mm x 4.2mm (L*W*T) Package Content: 1 x Thermoelectric Cooler Description: 1.Get ice cold in minutes or heat to boiling by simply reversing the polarity. 2.Used for numerous applications from CPU coolers to alternate power sources. 3.Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts. 4.Must be used in conjunction with a heat sink to avoid burned. Hot side needs heat sink all the time. Please Note: 1.Under cooling mode: Red wire to positive, black wire to negative. the surface with model number is cooling side. 2.When heating, just need to change the current polarity; when cooling, switching power supply is needed. 3.During installation, keep thermoelectric cooler clean, and apply the heat-conducting silicone grease evenly over both heating and cooling surfaces.
