No te. Evan if the thermo-electric cooler (TEC) is operated within the rate d conditions, uncontrolled current
loading or operation without heatsink may easily damage the mod ule by exceeding the storage. Th ermistor
resistan ce should be properly mon itored by the feedback circuit during TE C operation to avoid the
catastrophic damage.
