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 provide an extensive selection of TEC controllers, each engineered to meet diverse application requirements. Our solutions deliver accurate temperature control, enhanced energy efficiency, and reliable cost-effectiveness.
Explore our full range of TEC controllers to find the ideal match for your specific needs. With a variety of models and features, we have the right TEC controller to optimize your system's performance.
