Why Peltier Controller

When we mention peltier controller, we need to focus on peltier. Peltier comes from a Peltier effect, which was discovered by a French physicist, Jean Charles Athanase Peltier, in 19th century. Peltier is named after his surname. Peltier effect is also called thermoelectric effect, which converses temperature difference to voltage and vice versa. When there is a temperature difference on each side of a TE device, it creates voltage, and this TE device is called TEG. TEG can be used to generate electricity, but it has limited capacity due to low power. When there is a voltage difference on each side of a TE device, it creates a temperature difference, and this TE device is called TEC. TEC is now widely used in thermal system, such as solid state lasers, refrigerator, optical components, etc. 

For such a popular TEC device, it needs a peltier controller to control the direction of the current going through the TEC so that the thermal load temperature can be regulated accurately.

There are a series of peltier controllers in ATI. The max. output current can be 2.5A, 4A, or 6A, the power supply voltage can be 3.1V to 3.5V, 4.75V to 5.25V, and 4.75V to 6V.
