How and Why Our TEC Controllers Have the Highest Efficiency on the Market
TEC (Thermo-Electric Cooler, or Peltier Cooler) is a semiconductor device which can cool down or heat up the temperature of a thermal load depending on the direction of the current going through the two terminals of the TEC. By using a TEC controller, the thermal load temperature can be regulated precisely by controlling the direction and magnitude of the current going through the TEC.
We have been developing TEC controllers for over 21 years and accumulated many innovative designs, among them, the most critical invention is our unique design of the output driving stage which uses only 1 PWM engine, as opposed to 2 PWM engines by all others' designs. This special design was awarded a US patent to us in 2001. The patent number is US 6486643 B2 and you can read the pdf file for the patent here: US Patent US 6486643 B2
We have a variety of TEC Controllers.
