Long Life TEC Modules Thermoelectric Cooler Peltier Module 127 Pairs 6A 18.1V 60W 29.7mm*29.7mm*3.5mm DTmax 79 degC with Sealed Edges ATE1-TC-127-6BSH

This TEC (Thermoelectric Cooler) module has 127 pairs of Peltier elements inside with a maximum voltage of 18.1V. They are designed for temperature cycling applications, in which a TEC module is exposed to demanding physical stresses as the module shifts from heating to cooling, and this can significantly reduce the operational life of a standard TEC. This long life time TEC has significantly longer life span than standard TECs.
This TEC module can be controlled by our TEC controllers to build highly stable and efficient temperature regulating systems. It can be used with our thermistors as well to achieve precise and stable temperature sensing.
This TEC module comes with highly flat bare ceramic surfaces on both sides. They can be mounted onto flat metal surfaces by inserting thin layers of thermally conductive filler materials, the so-called thermal pads, or adding a thin layer of thermal paste. When mounting, make sure that proper pressure is applied constantly to keep good thermal contacting between the metal and the TEC plates, minimizing thermal resistance between them.
The TEC can withstand strong orthogonal forces applied to the surface, but very vulnerable to tangent forces, especially shocking tangent forces. A small shocking tangent force can cause the Peltier elements to crack inside. The crack may not cause operational problem initially, but it will grow with time, causing the TEC resistance to increase slowly and the TEC will stop operating.
This TEC module comes with 2 insulated lead wires. The positive wire is coated red, and the negative wire is coated black.
This TEC module has the edge area be sealed, are to prevent moisture from getting into the Peltier elements and to extend the life time.
