SORT - when viewing product tables, you may sort each data column by increasing or decreasing values by clicking the arrow next to each column header

• • Qc Op - displays the cooling performance of the thermoelectric module at the temperature difference requested. The cooling performance shown is at the operating point determined by the supply voltage. By clicking on the part number, cooling performance (Qc) can be viewed graphically over the entire operating range from minimum to maximum voltage or current (Imin to Imax or Vmin to Vmax)
• • Power Supply - the power consumed by the thermoelectric modules, as well as any fans in air-cooled models
• • Supply Voltage - displays the nominal supply voltage designed to achieve the rated cooling capacity of the assembly. The fan and thermoelectric modules in the assembly can be operated at higher or lower voltages depending on the cooling load required and efficiencies required
• • Qc Max - the maximum cooling performance capability of the thermoelectric assembly. This value is measured at zero temperature difference with the supply voltage set to the nominal value. Actual thermoelectric assembly performance is usually less than QcMax because of the requirement to operate through some temperature difference
• • ΔT Max - displays the maximum difference in temperature seen across the thermoelectric assembly. This value is measured at zero heat flow (Qc) with the supply voltage set to the nominal value. The thermoelectric assembly is typically operated at ΔTs less than ΔT Max in order to move heat from the cold to warm side of the thermoelectric assembly

PART NUMBER - displays an active data sheet. You can fine-tune your application requirements by adjusting values for voltage, current, control temp, ambient temp, ΔT, Hot Side thermal resistance or Cold Side thermal resistance and then click the UPDATE button.
