TheATFC107Dis a digital Peltier controller, which is designed to monitor and regulate the temperature of TEC/Fan assembles. When using the digital Peltier controller, there is no need of heat sinks, so it is convenient to use, carry and store. And the ATFC107D (see Figure 1) is packaged in a metal enclosure and keep from the interferences between the controller and other electronics. (more)

TEC module is short for Peltier Cooler Module, which can heat up or cool down the target object by inserting currents of different directions. For standard TEC modules, when they shifts from heating to cooling or cooling to heating, the modules are exposed to large physical stresses, which will largely reduce the operational life of TECs.(more)

The TEC5V6A-D is an advanced Peltier controller with the power supply voltage from 4.75V to 6V and the maximum output current 6A. It is used for drivingthermal electric coolers (TECs) to monitor and regulate the temperature. This Peltiercontroller provides DIP packaging. It is very easy to be soldered manually on the board by a solder iron of < 310 °C, but it cannot go through a reflow oven process.(more)

ATLSXA103 series laser drivers come with ultra low noise and compact size. These laser drivers need no heat sink to dissipate since the maximum power consumption of these laser drivers is kept to less than 1W. ATLS1A103DEV1.0 is an evaluation board that is designed and used to conveniently evaluate laser drivers of DIP package.(more)

Continued from last article.We are introducing liquid level measurement for NTC thermistor. In the water and air of the same temperature, and under the same electrical condition, a constant current is provided to NTC thermistor, and make the thermistor produce self-heat. The voltage of NTC thermistor is relatively stable after heat balance. Then put it into the water, the voltage of NTC thermistor rises. That’s because when NTC thermistor enters into the water, the temperature falls, resulting in a resistance increase and the terminal voltage increase. The heat capacity of water is 2.5 times higher than the air, so the self-heat temperature in the water needs 2.5 times power than that in the air. (more)

The TECA1-XV-XV-D Peltier controller is designed to drive thermal electric coolers (TECs), and its parameters can be customized. This Peltier controller has a compact size, 25.6mm*20mm*7.5mm (see Figure 1), so that it is very easy and convenient to use, carry and store. In addition, the Peltier controller has high reliability, high stability and some other advantages.(more)

The TEC5V4A-D is a Peltier controller, which is designed for driving thermal electric coolers (TECs). This Peltier controller has high efficiency (more than 90%), high stability (±0.01°C) and so on. It provides a DIP packaging.(more)

NTC thermistors are sensitive to air flow when they are in self-thermal status, so NTC thermistors has potential to measure wind velocity. Under the same temperature and electric condition, such as stable room temperature, provide a constant current to NTC thermistors for self-thermal. Put NTC thermistors in still air, at this time, the terminal voltage is the lowest. Then increase the wind velocity generally, and the terminal voltage increases accordingly. That’s because the flow air decreases the self-thermal temperature of NTC thermistors, and the resistance increases. More fast is the flow air, more obviously the temperature falls. Vice versa, when we know how much the self-thermal temperature falls by detecting the terminal voltages, we can know the wind velocity. This is the principle of wind velocity measurement.(more)

The TEC5V4A-D is a patented Peltier controller of ATI, with high efficiency, high stability, and high reliability. This Peltier controller has a compact size (see Figure 1), and is packaged in a metal enclosure, helping to block the interferences from other electronics. It is utilized to drive thermal electric coolers (TECs).(more)
