Thermoelectric cooler (TEC) is built on the thermoelectric system, which can both cool and heat, depending on DC current direction. As TEC has no refrigerant, no pollution, no rotation parts, no noise, long service lifetime and some other advantages, it has been widely used in electronic fields, laser fields and so on.(more)

Peltier controller is an independent research and development product of ATI, which is designed for drivingthermoelectric coolers (TECs) to regulate the object temperature. Peltier controller has many good characteristics, such as high energy efficiency, high stability, high accuracy, compact size, etc. As shown in Figure 1, this Peltier controller packaged in a six sided metal enclosure has zero EMI to avoid the interference with other electronics. Peltier controller can realize such functions as thermistor T-R curve linearization, temperature measurement and monitoring, temperature control loop status indication, TEC voltage monitoring, power up delay, and shut down.(more)

With the development of science and technology, there are more and more researches about thermoelectric cooler (TEC) and the achievements on the improvement of the material optimal value and the optimization of thermoelectric cooler has been obtained. Now TEC has been widely used in many fields, and along with the time and research development, TEC will play more and more important role in the electronic and some other fields.(more)

TEC5V4A-D is a kind of Peltier controller, which is used to monitor and regulate the object temperature. The maximum output current of Peltier controller TEC5V4A- Dis 4A and the maximum output voltage is 4.7V. This Peltier controller has high efficiency and high reliability. Peltier controller provides two packaging methods, DIP package and SMT package. The following is the physical photo of Peltier controller TEC5V4A-D.(more)

Continued from the last article. Since the kits are small, it’s easy to carry it when you go out. You can just put it into your bag, as easy as carrying a book.The kits enclosure has a letter paper size: 11”(L) × 8.5”(W) × 2.2”(H) (279mm(L) × 216mm(W) × 56mm(H)). In addition, the compartments form a matrix of 8 rows × 16 columns.(more)

Thermoelectric cooler (TEC) is built based on Peltier effect. It is a kind of solid components, which has no pollution, high reliability, small size, rapid cooling, rapid heating and some other characteristics. It has been widely used in electronic, medicine, industry, agriculture and some other fields. However, TEC still has some problems.(more)

Continued from the last article. We have SMT kits with components already sorted inside, i.e. resistor kits, capacitor kits and inductor kits. These kits have different quantities and component values presorted in the kits.(more)

ATH10KL2A is a kind of NTC thermistor, which is packaged with glass.The resistance value of NTC thermistor ATH10KL2Ais 10K at the temperature of 25°C. This NTC thermistor comes with an extra small ring lug for being fixed easily. As NTC thermistor ATH10KL2A has compact size, short respond time and some other good characteristics, it has been widely utilized to measure the temperature of laser diode, optical elements, etc.,with high accuracy and long term stability. Figure 1 is the physical photo of a NTC thermistor ATH10KL2A.(more)

High reliability and long life time can be achieved when the thermal cycling times is few, the temperature change range is narrow, upper temperature limit is low, as well as that temperature change is slow. On the contrary, in a wide temperature range, high changing speed, many times cycling, it will shorten the life time of TECs largely. It's noteworthy that the absolute life time of TECs depends largely on the total cycling times, not the total time for the cycling.(more)

Peltier controller is also called TEC controller, is an electronic device which is used to regulate the thermal load temperature. The temperature of the thermal load can be increased or decreased by using a TEC depending on the current direction going through the two terminals of the TEC. By controller the direction of the TEC current, peltier controller can regulate the temperature of the thermal load.(more)
