Multi-Stage Thermoelectric Peltier Modules

The Multi-Stage Thermoelectric Peltier Modules, also known as multi-stage thermoelectric elements or cascade modules, can built up high deltaT between the hot and cold side of the component. These Peltier elements are suitable for applications with very low target temperature where a low to medium cooling capacity is needed.

Typical applications are for example:

  • IR detectors
  • CCD array
  • Electro-Optics
  • measurement setups for very low temperatures
  • Testing of Materials Test

These items are available in various cascade designs with different numbers of stages. Generally speaking, the more stages a module has the greater the achievable deltaT but the lower the possible thermal pumping capacity.

Uwe electronic as specialist for thermoelectric modules has a vast experience in the application of multi-stage Peltier modules.

Peltier Kaskadentypen

Type 2 (T2) TEMs feature a "porch" for more accurate heat distribution.
This makes the L2 dimensions slightly longer than the L1 dimension.

Imax: Maximum input current in amperes at Qc=0 and ΔTmax
Vmax: Maximum DC input voltage in volts at Qc=0 and ΔTmax
ΔTmax: Maximum temperature differential in °C at Qc=0 and Imax
Qcmax: Maximum heat pumping capacity in watts at Imax and ΔT=0
T hot: Temperature of TEM hot side during operation
