area is contacted with the environment intensively. That implies that by the usage of a heatsink
the surface gets enlarged multiply to establish the needed contact with the ambience. The size of
this heatsink and the impeccable bonding between Peltier element and heatsink on the one side
and between Peltier element and heating and cooling plate, respectively, on the other are the
basic conditions for the determination of the performance of their setup. If you always focus on
that basic structure, your results will be successful. Please visit the category

3. The electrical setup:
The wiring of the single components with the controller requires basic knowledge of electrical
engineering and has to be conducted by a qualified person.
To run the controller, a source of direct current voltage is necessary. Sources in the range of 12VDC
to 24VDC are usable. The controller has a separate power input for the supply of the Peltier element
available. The zero potential of both voltage sources is merged on the black wire. Thus, the control
supply and the Peltier supply can either be separated or alternatively connected.
