Abstract: A thermoelectric cooling system includes a control assembly and a direct current (“d.c.”) power source providing direct current to an interface that creates a thermal flow across a thermoelectric module having at least one heat sink and at least one heat source. The d.c. power source, the interface, the control assembly, and the thermoelectric module are connected to each other in series. The control assembly optionally includes a relay and a voltage generating thermocouple. When voltage from the thermocouple reaches a predetermined threshold, the relay trips and supplies sufficient voltage to the interface to prevent thermal reversal of the heat source and heat sink. To control moisture, a metal strap may be used to restrict heat flow. Alternatively or additionally, a moisture control pad may be used to absorb and re-evaporate moisture to substantially maintain a desired humidity range. In an optional embodiment, the load to be cooled may be placed below the heat source and cooled by convection.
