Peltier Thermoelectric DeviceWhen a voltage is applied, a temperature difference is created from one side to another; one side gets cool while the other gets hot. Changing the voltage polarity reverses the hot and cold sides. Furthermore, the reverse is alsotrue; when there is a temperature differential, one side to another, a voltage is created.These are suitable for mini DC refrigerators or coolers. 12VDC~5 amp 130mmx127mm x 96mm10″ Leads
