3. The electrical setup
To run the controller, a source of direct current voltage is necessary. All sources in the range of
10VDC to 24VDC are usable. Please consider that the controller is not adjustable to any current or
voltage limits. I.e. the controller transfers the full voltage to the Peltier element, if in case of
maximum heat requisition the nominal temperature is much higher than the actual temperature.
Therefore make sure that the supply voltage does not exceed the maximum permissible voltage of
your Peltier element (flexible film heater) or concatenate several Peltier elements in series until the
sum of all single voltages reaches at least the value of the supply voltage. Care has to be taken that
only equal elements are wired up to guarantee a consistent distribution of the voltage. Fig. 2
depicts the wiring of the single components of the control circuit. The colors correspond to the
colors of the wires of the controller.
If you follow this circuit diagram and use Peltier elements from QUICK-OHM, the imprinted side
will get cold and the blank side will get hot.
