TEC - Controller QC-PC-C01C

Manual

Temperaturecontroller for Cooling

Technial Data:

Dimensions: 65mm x 50mm x 20mm

Temperature range: -20°C…+50°C

Input voltage: 10V…24V

Max. output voltage: equal to input voltage

Max. output current: 10A

1. Basic information QC-PC-C01C

The QC-PC-C01C was designed as controller for cooling to adjust a TEC (Thermoelectric coller)

at a certain temperature. The controller is operated by low DC voltage and should not be exposed

to main voltage. To set up the controller electrical wiring is required, which request some basic

knowledge of electrical circuits. All wiring must be done without connection to the power supply.

Be aware that same components can be damaged or destroyed be incorrect use. Despite of low

voltage, high currents can occur and serious warming and the danger of fire can appear by using

wrong lead wires. Please read this instruction carefully and consult an electrician by any question.

If you remark any warming during operation, the controller must be switched off immediately.

. Operating principle: A TEC is able to transfer thermal power from one side of the module to the other by consuming electrical power. The temperature drops on one side of the element, because of heat consumption while it rises on the other side. For using this heatpump effect in a technical application, a setup similar to figure 1 is to be built up. figure 1: Temperature sensor Temp. controlled area/ cold side Thermal conductive (Paste, Foil, etc.

. 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.

Controlling characteristics: The following figures show a typical control mode of the temperature as function of time. In this example, the set-temperature is lowered from ambient temperature to -15°C. The left figure shows the current, the right figure the temperature. This shows an optimal behavior of the controller.
