How can I power a Peltier Thermoelectric Cooler

  1. Hi I recently purchased a small (15mmx15mm) Peltier Thermoelectric Cooler/Heater. I am using this for a prototype of mine but I can't find a way to power it. The specs are 1Amp 0.8Volts.
    I was just wondering if anyone knew where to find a power supply (DC) to power it. I could also use resistors, but i'm not quite sure how to do so. This all has to fit within a size of about the length of a pencil with a width of a ruler (cylinder).
    Any input will be greatly appreciated, Thanks,
    Zach

    zmillerkoren (Zach), Welcome to Physics Forums!

    The power supply you need is: Model 442-1A: Temperature Controller

    It is used in this detector:
    Model ID-441-C
    InGaAs Near Infrared Detector
    with Preamplifier and Thermoelectric Cooler

    I could not find how or where to buy it, however. Princeton Instruments and Acton Instruments sites were no help. Wherever you acquired your Peltier Thermoelectric Cooler/Heater ought to be able to either supply one, or tell you how to locate it.

    Cheers,
