Can I use Chroma TEC controller to drive the TEC platform I had or to be designed by myself?

Of course. However, precautions should be taken before use, such as current limit setting to avoid over current damaging the platform and PID auto tune for optimal performance. T-type thermal couples should be used as temperature sensors for correct measurements. Please note TEC platform design requires certain knowledge including thermoelectric, thermal analysis, mechanical design, and system integration. Customers can do their own or come to us for help.
