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 amplitude of the current going through the TEC.
We have been developing TEC controllers for over 21 years and accumulated numerous innovative designs, among them, the most critical invention is our unique design of the output driving stage which uses only one PWM engine, as opposed to using two PWM engines by all others' designs. This special design was awarded a US patent, US 6486643 B2. This design cuts the power loss by 20%, component cost by 25%, PCB component area by 35%, resulting in a highest efficiency and lowest cost TEC controller on the market.
We have a variety of TEC Controllers.
