NTC Thermistors ATH10KL2C Series

In the previous two articles, NTC thermistor series ATH10KBL2A and ATH10KL2B have been introduced already. In this article, we will focus on ATH10KL2C series NTC thermistors. This NTC thermistor is also packaged in a small ring lug for easy mounting. Inside the ring lug, there is a thermistor head, ATH10K1R25, which is also in ATH10KL2B NTC thermistors. Therefore, the three thermistors have the same characteristics.

The length of the ring lug of ATH10KL2C series thermistors is 11.2mm, and the width is 5.5mm. The length of the lead wires of this series NTC thermistors is 70mm. Therefore, the three versions come with the part numbers, ATH10KL2C, ATH10KL2CT70 and ATH10KL2CT70S. 70 refers to the length. As mentioned in the last two articles, ATH10KL2CT70 and ATH10KL2CT70S have plastic tubing covered with the lead wires and the latter is the sealed version.

NTC thermistor can work with TEC module and heat sink in order to measure and control temperature in some systems.

As the part number indicates, ATE1-241 series TEC modules come with 241 pairs of Peltier elements. Peltier elements are the basic components of TEC module, which is also called Peltier module or thermo electronic cooler. TEC modules are designed for temperature regulation on target objects.

The maximum input voltage of this series TEC modules is 28.9V, with different power ratings and dimensions. The maximum temperature difference is 68°C, which can be achieved by single stage TEC module. If a higher temperature difference is needed, then two or more stages TEC modules should be utilized. All the TEC modules in this series are sealed version, which can prevent moisture from entering into the Peltier elements. Therefore, if the TEC modules are used in moisture temperature, the sealed version is highly recommended.

ATE1-31 TEC Module Series

TEC module is short for thermoelectric modules, and also called Peltier cooler. The reason why it's called Peltier cooler is that it has multiple Peltier elements inside the TEC module, which are the main components in the TEC module. TEC modules can be used to regulate the temperature of an object and stabilize the temperature in a certain temperature range. As indicated in the part number, ATE1-31 series TEC modules have 31 pairs of Peltier elements inside the TEC module, and it is a single stage TEC module.

There are two flat ceramic plates on both side of the TEC module outside the Peltier elements. There are mainly three methods to install TEC modules, i.e., bonding with epoxy, clamping and soldering. Soldering is the most efficient way to use the TEC modules, but it's not convenient for maintenance. Clamping and bonding with epoxy are relatively simple and easy for most users by using thermal conductive pad or thermal paste.

Peltier Cooler ATE1-288 Series

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 68°C. 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 elements inside the TEC module. The crack caused by tangent forces will grow with time, resulting in increases of TEC resistance and finally stopping operating. Therefore, for all TEC modules, tangent forces should be avoided when using TEC modules. All ATE1-288 series TEC modules are sealed version, which have the edges between the two plates sealed. Sealed TEC modules can prevent moisture from getting into the Peltier elements, which can help achieve long service life and high stability.

When this laser driver is powered by a 5V power supply, the output voltage is 1.5V to 4V. There is a temperature compensation network inside the laser driver, which can maintain the output current unchanged even as the laser driver temperature rises. Moreover, a overheat protection circuit is also provided inside the laser driver, when the temperature exceeds 120°C, the laser driver will shut down itself automatically in order to prevent it from being damaged by over heat.

This laser driver is compact in size. There are two packages available, DIP package and SMT package. Both DIP and SMT packages laser drivers can only be soldered manually on the PCB by a solder iron of < 310ºC.

TECA1-xV-xV-D Peltier Controller

Peltier controller TECA1-xV-xV-D is a TEC controller with high efficiency and high stability. The efficiency is more than 90% and the stability is 0.01°C. This Peltier controller comes with a maximum output current of 2.5A. The maximum output voltage is 0V ~ (VPS − 0.2V). The input voltage can be 3.1V ~ 3.5V or 4.75V ~ 5.25V. This TEC controller has a wide operating temperature range, from −40°C to 85°C.

This Peltier controller has many functions, such as temperature measurement and monitoring, temperature control loop status indication, thermistor T-R curve linearization, TEC voltage monitoring, power up delay, and shutdown. The TEC controller also provides some interface ports in order for users to set the target temperature, i.e. set-point temperature; the maximum output voltage across TEC; and the compensation network.

There is also an updated version of this Peltier controller, TECA1-xV-xV-DAH, which comes with a higher precision. ForTECA1-xV-xV-DAH, the maximum voltage difference between TEMP and TEMPSP is ≤0.5; for TECA1-xV-xV-D, this voltage difference is ≤25.

This Peltier controller can work with our Peltier module, thermistor, and heat sink, to form a temperature control system.

High Precision TECA1-xV-xV-DAH Peltier Controller

Peltier controller TECA1-xV-xV-DAH is the updated version for the TEC controller  TECA1-xV-xV-D. This Peltier controller has a higher precision, as shown in the table below. The TEC controller is also called Peltier controller, which is used for driving thermoelectric coolers in regulating temperatures in temperature control and measurement system.

Part #	Maximum |VTEMP − VTEMPSP | (mV)
TECA1-xV-xV-DAH.html' target='_blank'>TECA1-xV-xV-DAH	≤0.5
TECA1-xV-xV-D	≤25

 

This Peltier controller comes with a compact size, which saves much space for the system. It also provides multiple interface ports for setting the desired target temperature, i.e. maximum output voltage across TEC, set-point temperature; and the compensation network. The last one compensates the high order thermal load, stabilizing the temperature control loop.

The maximum output current is 2.5A and the stability is up to 0.004C. There is a high stability low noise 3.0V voltage reference that is used for setting the desired target temperature by using a POT or a DAC. Moreover, this reference can also be used by an ADC.  

This Peltier controller can work with our Peltier module, thermistor, and heat sink, to form a temperature control system.
