A thermoelectric cooler (TEC) module is a solid state device which can control heat flux using current. It is very useful in small scale temperature control, providing fast temperature response and ultra-high temperature stability. TEC temperature control equipment can also be very compact and environmentally friendly.
Chroma’s Advanced TEC Controllers have an excellent temperature monitoring engine, which allows 2 T-type thermal couple inputs. The cold junction of the engine is internally stabilized up to 0.001℃, for that 0.01℃ temperature resolution and control stability can be achieved. The TEC driver uses a filtered PWM architecture, which obtains high driving power efficiency as ordinary PWM drivers have, but smooths the current modulation to a DC-like output. It’s very important for electro-magnetic sensitive measurements.
Another important feature of Chroma’s Advanced TEC Controllers is the true TEC PID auto tune function. Chroma’s Advanced TEC Controllers have a unique auto tune algorithm to guarantee the best control and temperature response. Stability down to the temperature resolution, which is 0.01℃, is regularly achieved, regardless of the size and geometry of thermal platforms.
High TEC driving capability is another merit of Chroma’s Advanced TEC Controllers. Chroma’s Advanced TEC Controllers deliver 150W, 300W for high power TEC driving. More TEC driving power means wider temperature range, faster temperature response, and larger platform applications. For comparable accuracy and stability, Chroma offers one of the best TEC driving power to price ratio in the market.
