Description: This is TEC1-12706 40x40mm cooler Peltier plate module 12V 60W Get ice cold in minutes or heat to boiling by simply the polarity, used for numerous applications from CPU coolers to alternate 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 Feature: Its work is characterized by side refrigeration and side fever. Hot and cold on both sides of the temperature difference of 68 degrees Connected to the 12-volt supply cooling piece on both sides there will be difference in temperature, side cold side of the heat, do not long cooler , otherwise it will cause cooler internal overheating and burning. Specification: Model: TEC1-12706 Size: 40mm x 40mm Operates from 0~15.2V and 0~6A Operates Temperature: -30C to 70C consumption: 60W 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 Installation: 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 end of fever, remember that the polarity of the lead and determine a good cooler cold and hot end. 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 condition can choose three, of course, have a large supply . a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a
