3. Electrical connection:
For operating the controller a DC power supply is needed. Please be aware that the controller has
no internal voltage or current limits and therefore will output the maximum voltage of the power
supply when the set-temperature is much lower than the actual temperature. Make sure, that the
maximum voltage of the power supply is within the range of the TEC. A series connection of
similar TECs can also be used to reduce the voltage for each TEC. Figure 2 shows the electrical
connection of the whole circuit, the colors follow the lead colors of the controller.
By following these instructions and using TECs from QUICK-OHM, the top side of the TEC will
get cold when the right wire showing in the direction of the viewer is red. Applied on the figure
above, the top side would be the warm side.
4. Temperature setting:
The controller has a working range from -20°C to + 50°C. Please notice, that the controller can
only be operated in cooling mode. 50°C can only be reached, when the hot side is above this
temperature. It could be useful to make marks on the potentiometer while the first use. By
adjusting some positions between the left and right stop of the potentiometer and while measuring
the temperature at that steps a small scale can be marked on the potentiometer.
It is possible to integrate a Display (QC-PC-D-100) in the setup. This device shows the set-
temperature as well as the actual temperature.
