A Thermo-Electric Cooler (TEC), also known as a Peltier Cooler, is a semiconductor device that can either cool down or heat up a thermal load by reversing the direction of the current flowing through its terminals. A TEC controller precisely regulates this temperature by controlling both the current direction and amplitude.
For over 28 years, we have been at the forefront of TEC controller development, continuously refining our designs. One of our most critical innovations is our unique output driving stage, which utilizes only one PWM engine—unlike conventional designs that require two PWM engines. This groundbreaking approach, protected under U.S. Patent 6486643 B2, results in:
20% lower power loss
25% reduction in component costs
35% reduction in PCB component area
By implementing this patented design, our TEC controllers outperform competitors with the highest efficiency and lowest cost in the industry.
We offer a wide range of TEC controllers tailored to different applications, ensuring precise temperature regulation, high efficiency, and cost-effectiveness.

We have a variety of TEC Controllers.
