There is an urgent need in the market for high voltage laser driver. High voltage laser driver is designed for driving a serial of diode laserssimultaneously, recently we developed ATLSXA212 series laser drivers . The power supply voltage (VPS)is between 4.75V to 16V and the output voltage can be from 1V to (VPS -1V), e.g. the maximum output voltage can be 14V when powered by a 15V power supply. This series laser drivers come with three current, 1A, 2A and 3A. ...(more)
Laser driver with high output voltage is capable of driving one or more laser diodes simultaneously. The input voltage can be 5V to 16V, and the output voltage is from 0V to 15V. The laser driver generates ultra low output current noise : 12A@0.1Hz~10Hz, with high current stability 600A@4A －20C~80C. Though this laser driver comes with high efficiency 92%, it doesnt need heat sink to dissipate heat, a small amount of heat....(more)

This laser driver allows a wide input voltage range, from 5.5V to 15V, as well as wide output voltage range, from 0.8V to 80% input power supply voltage. There are three control modes, shutdown, standby and operation. This laser driver also comes with a low current noise. It...(more)
As a special cold source, TEC module has the following advantages and characteristics: no need for any refrigerant, continuous working, no pollution, no rotating parts or rotating effect. It is a solid device without sliding parts, or vibration and noise during operation, long life, easy to install. TEC module has two functions: cooling and heating. The cooling efficiency is generally not high, but the heating efficiency is high, always greater than 1. Therefore, a single device can replace disc...(more)
Thermistor is a type of sensitive components, which can be divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC) according to different temperature coefficient. Thermistors are typically temperature sensitive and exhibit different resistance values at different temperatures. For positive temperature coefficient thermistor, the higher the temperature, the greater the resistance. For negative temperature coefficient thermistor, t...(more)
TEC is the abbreviation of thermo electric cooling modules. It has the characteristics of small size and light weight, which can conveniently control the cooling and heating by changing the current direction, and has good temperature response, local temperature control and high control precision. It is widely used in biomedical, testing and analyzers, electronic equipment and other fields. Although TEC comes with many advantages, in practical applications, it is not easy to drive TEC due to the...(more)
