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.

Chroma’s TEC controller uses thermoelectric based technology, which enables heating and cooling

using one controller and one device from -70℃ to +180 ℃.

Traditional Methods

Using Chroma's TEC

method, rising and falling

of temperature is about

5~60℃ per minute via

thermal contact

conductance.

Using traditional methods yield much slower

temperature changes- as little as 1℃ per minute-

due to convective temperature transfer.

• 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.
