This series of TEC (Thermoelectric Cooler) modules,ATE1-TC-71, has 71 pairs of Peltier elements inside with amaximum voltage of 9.0 Volt. They are designed fortemperature cycling applications, in which a TEC module isexposed to demanding physical stresses as the module shiftsfrom heating to cooling, and this can significantly reduce theoperational life of a standard TEC. This long life time TECshave significantly longer life time than standard TECs.
