TEC modules are used to regulate and stabilize the temperature of the target object. TEC modules can cool down or heat up the target object according to the direction of the current going through the two terminals of TEC modules. How to select a proper TEC module? First the maximum temperature difference is a major parameter in selecting TEC modules. Commonly, the temperature difference is between 60C and 72 C. Higher temperature difference can be achieved by choosing a two stage or multiple sta...(more)
NTC thermistors ATH10KR8B is the replacement for a similar NTC thermistor ATH10KR8 that has stopped production. This NTC thermistor is glass encapsulated, which has longer term stability and reliability than epoxy encapsulated NTC thermistors. The resistance accuracy is 1% and the thermistors have a short response time, 0.14s in the water and 2s to2.2s in still air at 5~25C. This series NTC thermistors have very compact size, 0.8mm*1.4mm, which can be used in application with limited space. Ther...(more)
ATE1-288 series peltier coolers / TEC modules come with 288 pairs of Peltier elements inside. This series TEC modules have the maximum Peltier elements and the input voltage of 35V. The maximum current can be 6A, 7A, 8A, 9A, 10A, and 20A. The temperature difference between the two ceramic plates is 68C. If a higher temperature difference is needed, then users can utilize two stage TECs or three stage TECs. TEC modules are vulnerable to shocking tangent forces, which can crack the Peltier element...(more)
ATE1-127 series Peltier cooler comes with 127 pairs of Peltier elements between the two flat ceramic plates. The maximum input voltage of this TEC module is 15.4V. The maximum current is selectable from 3A to 18A, resulting in different power ratings. This series TEC modules come with two different operating temperature ranges: one is from 60C to 85C and the other is from 60C to 200C. The latter has an part number with a suffix H, standing for high temperature, while the former doesnt have this...(more)
Peltier module is also called TEC module, short for thermo-electric cooler. ATE1-07 series Peltier modules come with 7 pairs of Peltier elements inside the module. There are two flat ceramic plates on the both sides, which are used to be mounted onto other surfaces by inserting thermal conductive materials, such as thermal pad or thermal conductive paste. This Peltier module is used to regulate the temperature for objects and stabilize the temperature in a certain temperature range. TEC modules...(more)
201 series constant current laser diode drivers are designed and applied for driving diode lasers with a maximum current of 1A, 2A, 3A, 4A and 6A. This laser driver ATLS1A201D comes with up to 1A low noise current. There are two types of ATLS1A201D laser drivers, ATLS1A201D and ATLS1A201D-PD. The difference is that the latter has a pull-down resistor of 55K to the ground in SDN pin. This laser driver has a compact size and is packaged in a six sided metal case, which blocks outgoing and incoming...(more)
In the last article about 201 series laser drivers, we mentioned that the maximum current can be 1A, 2A, 3A, 4A and 6A. Therefore, this article is about 2A laser driver, ATLS2A201D. This laser driver has a high efficiency of 90% and a high stability of 100ppm/C. This laser driver will shut down when receiving one of the three signals, external shut down, over current and over temperature signals. Any of these signals is activated, the laser driver will shut down. Only if all the three signals go...(more)
Laser diode driver ATLS500MA104 is used for driving diode lasers with up to 500mA ultra low noise current. This laser driver comes with many features, such as ultra low noise, high output current, high output current stability, compact size, complete shielding, etc. When it is powered by a 5V power supply, this laser driver can output a voltage range from 0.5V to 3.6V. The output current of this laser driver can be set by an input voltage linearly or modulated by an external signal of up to 100...(more)
