See tabs below for comprehensive information on TM 127-1.4-6.0

TM-127-1.4-6.0 is multi-purpose single-stage thermoelectric module and is our most popular 40 x 40 mm module intended for use with 12 to 15 volt DC power sources. Although it doesn't have the greatest Qmax of our modules in this configuration, it's a solid performer that can be used with a variety of economical extruded heat sinks, without the hot-side temperature becoming unreasonably high.

May be used for cooling, heating and temperature stabilization and may be employed in a wide range of applications including refrigeration, consumer goods, instrumentation, medical, analytical, laboratory & scientific instruments, telecommunications, electro-optics, industrial and military.

Operating temperature range: -50 °C ~ +200 °C

Comply with ROHS (Restriction of Hazardous Substances) and 2006/122/EC - PFOS (PerFluoroOctane Sulfonates)

Specifications (Hot-Side Temperature 27 °C)

Imax = 6.0 Amps (Imax is the maximum current at ΔTmax)

Vmax = 16 Volts (Vmax is maximum voltage at ΔTmax)

Qcmax = 56 Watts (Qcmax is maximum cooling capacity at Imax, Vmax and ΔT = 0 °C)

Performance Curves with Th 27 °C

TM-127-1.4-6.0 Performance Curves at 27 °C  

In a forced convection assembly the hot-side (Th) of the TEC is in contact with a heat-sink that will always have a temperature above ambient. This curve is particularly appropriate for the many applications operating in an ambient around 22 °C with a typical 5 °C increase in the temperature of the heat-sink.

 

Performance Curves with Th 50 °C

TM-127-1.4-6.0 Performance Curves at 50 °C  

In a natural or forced convection assembly the hot-side (Th) of the TEC is in contact with a heat-sink that will always have a temperature above ambient. This curve is particularly appropriate for natural convection applications operating in an ambient around 20 °C with a 30 °C increase in the temperature of the heat-sink, a forced convection assembly within an instrument with marginal ventilation or an approximately 45 °C ambient temperature.
