4 1 Single Controller, Single Device Thermoelectric Cooler (TEC) A thermoelectric cooler (TEC) module is a solid state device which can control heat flux using bidirectional current. It is very useful in small scale temperature control, providing fast temperature response and ultra-high temperature stability. 3

5 1 Single Controller, Single Device TEC Controller 4

6 1 Single Controller, Single Controller, Single Device Device Chroma s TEC controller uses thermoelectric based technology, which enables heating and cooling using one controller and one device from -70 to TEC Module TEC = Thermal Electric Cooler; The main component of a Thermal Platform Chroma TEC Controller Traditional methods require two separate controllers and devices for heating and cooling. Heater Cooler 5 Heating controller (for heating) Compressor (for cooling)

7 2 Faster Excellent Thermal Thermal Response Response Chroma s TEC Controller Chroma s TEC Controller Using Chroma's TEC method, rising and falling of temperature is about 5~60 per minute via thermal contact conductance. Thermal Oven Thermal Stream Traditional Methods Thermal Control Oven Thermal Stream 6 Using traditional methods yield much slower temperature changes- as little as 1 per minutedue to convective temperature transfer.

8 3 High Temperature Resolution, Stability and Accuracy Chroma's Advanced TEC Controllers are thermal couple based and with temperature accuracy* 0.3 and resolution down to 0.01 compared to other TEC controllers who only have accuracy of about 1.0 and resolution 0.1. Users can take advantage of thermal couple for easy measurement setup, while maintain high accuracy and resolution. This means users can achieve test results with high repeatability, high accuracy, and therefore high confidence. 7

9 4 Smaller Size and Energy Efficiency Chroma s TEC Solution Size: < 50x40x30 cm 3 Power: < 300 W Traditional Thermal Oven Size: > 100x100x80 cm 3 Power: 1+ KW Thermal Stream Systems When testing LEDs, panel displays, ICs, optoelectronics components, etc., why use huge spaces for small devices that use excess power? Size: > 60x 80x 110 cm 3 Power: 6+ KW 8

10 5 Higher Output Power More TEC driving power means: Wider temperature range Faster temperature response Larger platform applications 9

11 6 PID Auto Tune PID = Proportional, Integral, Derivative Control Better Regulation and Stability Chroma uses Large Signal & Bidirectional driving for more accurate Auto Tune PID 10
