Semiconductor TEC temperature control platform and equipment Product introduction This series of "semiconductor temperature control platform and equipment" is a high-performance temperature control system designed on the basis of semiconductor refrigeration chip (thermoelectric refrigeration chip), which is characterized by high precision and stability, long life, small size, no noise, no wear, no vibration, no pollution, both refrigeration and heating, and is a real green product. This series of products have perfect PID control software and intelligent stepless temperature control, which can both heat and cool. It can be used to control laser devices, medical devices, semiconductor devices, infrared detectors, photomultiplier tubes, or any other place where temperature control is needed. This product adopts the latest modern power electronic devices and high-speed microprocessor (MPU) program control technology, as well as PWM modulation, bidirectional power supply and PID adjustment technology, and has excellent voltage and current output characteristics, no overshoot, backlash and surge when turning on and off the machine, and has over-current, over-voltage, over-temperature and under-temperature protection circuits, as well as RS232 or RS485 remote control interfaces. Note: In order to obtain the best accuracy, linearity and stability, this product adopts standard NTC (thermistor) imported from Japan as the temperature sampling element. Product features Intelligent stepless temperature regulation, bidirectional temperature control The temperature control accuracy is 0.1 degree or 0.01 degree. The working temperature can be set at will (usually between-60º C and 300º C, and other ranges can be customized). Alarm when the working temperature exceeds the upper/lower limit (set by software) Users can modify the temperature PID feedback parameters. Constant temperature mode: Two-way hot and cold constant temperature With over-current, over-voltage, overheating and other protection. With hardware over-temperature and under-temperature protection circuits. High stability, high anti-interference, completely eliminating 50/60Hz power frequency interference in the temperature sampling channel. DOT matrix liquid crystal or touch screen control Friendly man-machine interface and fault diagnosis function (in case of improper operation or power failure, the power supply will give a fault number prompt) Module size: Please refer to the product manual for details according to different product models. Accept customization: Temperature control platform, fixture platform, thermostat, thermostat, etc. Can be customized according to customer′s needs. Product application Temperature control of semiconductor laser, laser crystal and laser frequency doubling crystal Solid temperature control, experimental and scientific research temperature control High and low temperature experiments, etc.
