LDA1-CP2 is an electric module, which is designed by ATI to drive N type laser diodes. This laser driver can control and monitor the driving current and the output laser power well. The LDA1-CP2 laser driver comes with PWM output stage and the efficiency can be up to 90%, so there is no need of heat sinks. It is very convenient for users to use and carry. Figure 1 is the physical photo of the LDA1-CP2 laser driver.(more)

ATH10KL2A Series NTC Thermistors are similar to another two series ntc thermistors, ATH10KL2B and ATH10KL2C. The inner thermistor head of ATH10KL2A is ATH10KR8, thus, they have very similar characteristics. ATH10KL2A has a metal ring lug packaged outside the inner thermistor head, which is used for easy mounting.(more)

LED lighting is also called solid state lighting as the third generation lighting technology after the incandescent lamp and fluorescent lamp. LED lighting featuresenergy saving, environmental protection and high reliability. Nowadays, LED lighting has been widely used in daily life. Our company (ATI) has released a solarLED desk lamp, as shown in Figure 1.The LED lamp comes with eighteen LEDs, white light. The power is only 1.8 watt. The brightness is the same as a 15-watt incandescent lamp.(more)

NTC thermistors are more and more popular in many applications that need temperature control or measurement. ATI released several series of ntc thermistors including ATH10KR8B, ATH10KL2A, ATH10K1R25 and ATH100KR8 series. ATH100KR8 series ntc thermistors are mainly introduced here.(more)

The ATLS4A214 laser driver is an electric module, which is used to drive laser diodes with high voltage and constant current. The voltage range of the power supply is from 5V~16V. Because of high working efficiency, the laser driver needs no heat sink. This laser driver has a compact size, 27.4mm×20.9mm×8.9mm, as shown in Figure 1 and it is packaged in a metal enclosure to block electromagnetic interference.(more)

Based on Peltier effect, thermoelectric cooler (TEC) is built, which can both heat and cool, depending on the direction of DC current. TEC is a heat transfer tool. It has many advantages such as no refrigerant, high precision temperature control, compact size and so on. TEC has been widely used for temperature control of laser system temperature, refrigeration, water heater, air conditioner and computer CPU, etc. The working state of TEC is based on the current direction and size. In order to realize constant temperature control automatically, Peltier controller (TEC controller) is designed and produced. Our company (ATI) is very good at designing Peltier controller(more)

Thermistor is a kind of sensitive elements. According to different temperature coefficients, thermistor can be divided into positive temperature coefficient thermistor (PTC thermistor) and negative temperature coefficient thermistor (NTC thermistor). The typical characteristic of thermistor is temperature sensitive. With temperature increasing, the PTC thermistor resistance will increase and the NTC thermistor resistance will decrease. PTC thermistor and NTC thermistor both belongs to semiconductor devices.(more)

For a temperature regulating system, NTC thermistor is very important as the temperature sensor. Glass encapsulated thermistor has better performance than epoxy coated thermistor, such as zero short and long term drift, which is an important factor in order to achieve high system performance. Low cost epoxy coated NTC thermistor have large short and long term resistance drift, so when sensing the same temperature, the resistance changes with time, it will lead to a wrong sensed temperature, resulting in a drifted target object temperature. You can take some factors into consideration when choosing a proper NTC thermistor in temperature control system: operating temperature range, sensitivity, drift, size, mounting method, etc. Our NTC thermistors are all encapsulated with glass material, with compact size. Some thermistor come with bare leads, while some are lugged form. The former is used for point sensing in order to achieve high accuracy; the latter is for bulk temperature sensing, such as optical components, etc.(more)

Peltier controller is an electronic module which is designed for regulating the thermal load temperature. By using a Peltier module, the temperature of the thermal load can be increased or decreased, which depends on the current direction going through the two terminals of the TEC. Peltier controller can regulate the temperature of the thermal load with high efficiency and accuracy.(more)

Thermoelectric cooler (TEC) is solid thermoelectric effect. Comparing with traditional cooling method, TEC has obvious different features, simple structure, no moving parts, no vibration, no wear, high reliability, long service lifetime, etc. What’s more, TEC starts fast and it is flexible to control TEC. The following is the physical photo of TEC.(more)
