TEC controllers are used for thermoelectric cooling and heating in combination with Peltier elements or resistive heaters. Peltier elements are heat pumps which transfer heat from one side to the other, depending on the direction of the electrical current. TEC controllers are used to drive the Peltier elements.
This article explains how Peltier elements work, describes the features and shows where to buy Peltier elements.

TEC Controller Product Overview

How does a Peltier Element Work?

A Peltier element is able to transport heat from one side to another using the Peltier effect. Inside the Peltier element the Peltier effect produces a temperature difference between two conductors when a current is flowing. Thus heat is transported from the cold side of the Peltier element to the hot side, where the heat is absorbed by the heatsink and finally realeased to the air.

Depending on the direction of the DC current flow it's possible to cool and heat with Peltier elements, without changing the connectors or mechanical setup. The current supplied to the Peltier element is controlled by a TEC controller.

Technical Details & Basic Data

Peltier elements vary in size and form, power and temperature range.

Size range: 1 mm x 1 mm up to 60 mm x 60 mm
Forms: Square, ring form, multistage, sealed or non sealed, custom forms
Temperature range: Temperature difference dTmax up to 130 °C (Multistage), max. temperature up to 200 °C
Maximum cooling capacity: up to 290 W

Please refer to our TEC / Peltier Element Design Guide for detailed information on how to calculate and choose a Peltier element.

Connecting the Peltier element

The positive supply voltage has to be connected to the red cable of the Peltier element. Since cables have a thermal capacity they are connected to the hot side of the Peltier element, not to decrease the cooling capacity of the element.

Usually there is a manufacturer identification printed on the cold side of the Peltier element.
