TM 127-1.0-4.0 Thermoelectric Cooling Module
Specifications with Thot = 27 °С
30 x 30 x 3.65
TM 127-1.0-4.0 is powerful multi-purpose single-stage thermoelectric module and is our most popular 30 x 30 mm module intended for use with 12 to 15 volt DC power sources. TM 127-1.0-4.0 has an exceptional cooling capacity for its size and is typically powered by a 12V nominal supply.
At full power, TM 127-1.0-4.0 can provide up to 35 watts of cooling capacity. With the additional input power of up to 48 watts, a total of approximately 83 watts must be managed with heat-sinking. Be sure that you have a heat-sink, and air flow, adequate to manage this thermal load.
TM 127-1.0-4.0 may be used for cooling, heating and thermal stabilization and is employed in a wide range of applications including including medical, analytical, laboratory & scientific instruments, electro-optics, telecommunications and military. A version for thermal cycling is available.

Thermoelectric module performance curves are graphical representations showing the relationships between power applied and net cooling for a specific TE module.
Performance curves are valuable tools for quickly determining if a TE module is a suitable COOLER for an application; learning what power is required for an appropriate module to reach the desired temperature and heat pumping capacity; and to provide the basic information necessary for proper assembly design.
Curves with Th = 27 °C indicate what to expect operating in ambient temperatures around 20 °C (70 °F) with an operational "hot-side" temperature or Th about 7 °C above ambient.
Curves with Th = 50 °C are for outdoor, box-in-box, and other applications with ambient temperatures in the 40-50 °C range.
