DX8020
PL Engineering Ltd. introduces complex device TEC Expert DX8020 for detailed examining of thermoelectric cooling modules, measurement of their various performance parameters. The DX8020 provides automatic capability to measure full specifications of a TE module at one measuring cycle in given ambient conditions.
DX8020 key features
- DTmax, Qmax, Imax, Umax in a temperature range
- TEC operation at different heat loads to cold side and to middle stages (multistage TECs)
- Imitation of TEC operation in different applications
- AC Resistance, Figure-of-Merit and Time Constant in a temperature range
- Performance of TE Material (Seebeck constant a=ƒ(T), conductivity s=ƒ(T))
The DX80200 is intended for acceptance, qualification and research testing of TE modules.
