ITEM NAME:5 pcs TEC1-12706 Cooler Peltier Effect Thermoelectric Module 12V 60W 72W V8L8 5 pcs TEC1-12706 Cooler Peltier Effect Thermoelectric Module 12V 60W 72W V8L8 Model: TEC1-12706 Size: 40mm x 40mm x 3.8mm Voltage : 12V Umax (V) : 15V Imax (A) : 4.3-4.6A QMax (W) : 72W Power Cord : 300mm Net weight : 22g Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler. Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts These devices must be used in conjunction with a heat sink to avoid burned Each device is full inspected and tested Fitted with 6-inch insulated leads Cooling piece is very simple to install and use. Before installation, to find a dry cell, connected to the two leads of the cooler, obviously cold you can feel at one end and the other end of fever, remember that the polarity of the lead and determine a good cooler cold and . If you want to get a bigger system Ling, it is recommended that two cooling mode, with two stack up with the above, a grim absorption following a fever, the experiments prove two refrigeration effect is much better than the single-stage, the.Imax (A) : 4.3-4.6A QMax (W) : 72W. Before installation, to find a dry cell, connected to the two leads of the cooler. If you want to get a bigger system Ling.
