No te 1. Even if the thermoelectric cooler(TEC) is operated within the rated conditions, uncontrolled current
loading or operation without heat sink may easily damage the module by exceeding the storage
temperature range. Thermistor resistance should be properly monitored by the feedback circuit during
TEC operation to avoid the catastrophic damage.
