    100mA / Emitter on ground Intended use and description of the controller The QC-PC-PID-01 is used for controlling temperature. The controller detects the temperature via a PT1000 sensor (deliverables) and controls a peltier element with a continuously regulated DC voltage.

  • Page 5: Correct Polarity Of The Peltier Element

    (also called "cold side") is at the top. Quick-Ohm peltier elements have their imprint on the “cold side”. The object to be tempered must be thermally coupled to the cold side.
