    bookTECThe temperature control board is specially designed for the temperature control system adopting the semiconductor refrigeration chip, and adopts the innovative design scheme.High reliability and support.TECVoltageAnd currentA wide range.The accuracy of temperature control is0.01Degree! Use serial port to modify the setting temperature directly or call information. It has alarm readiness interface. This board is widely used in the field of laser diode temperature control.

    The board is simple, reliable and easy to integrate.This board adopts the most commonly used temperature sensor.10k NTC. Adopt innovative design scheme, small size, fewer components, low heat dissipation requirements, no need for auxiliary heat dissipation.The number of this boardPID algorithm,Robustness and adaptability. Unless there is a problem with the installation, there is no need to make any settings except to set the temperature you need.

    The board is directly controlled by a computer serial port. As long as you have a computer, plus a serial port line or USB to serial port line, you can control, the host computer software does not need to install, you can directly use the computer's own super terminal software, or any one of the serial port debugging software!Using the serial port to modify the setting temperature, and the call information, you don't have to buy any extra display operating parts, and the board has the function of communicating with other systems, such as another control board to set the temperature of the monitoring board. The same computer data is easy to process and save, and if you're a software expert, you can even make a computer software to achieve more complex functions.

     

     

    1With respect toTEC

    This board supportsTECWide range of voltage and current.TECVoltage7~24VRated current up to10A. The power supply voltage of this board isTECThe maximum voltage, so the power supply voltage should be based.TECFor example, for example15V/6AATECIt can be adopted.15VThe switch power supplies power to the temperature control board.12VIt can, but it will decrease.TECUtilization ratio. Make sure that the switching power supply voltage should not exceedTECRated voltage, so as not to causeTECOverload, switching power supply current must have some allowance, becauseTECThe general current at the beginning of power up exceeds its rated current.30%Above, so as not to trigger switching power supply overcurrent protection. If the TEC voltage is less than the supply voltage, it can be done, but the maximum duty cycle should be set.

    2With respect toNTCTemperature sensor

    Each panel will be equipped with a 10K 3950 NTC probe to the customer. NTC specific information can be seen in this store NTC probe separate links.

    Default support for this board10k, BValue is3950ANTC. HoweverBThe value is basically unlimited, becauseBThe absolute value of temperature will be affected, but the temperature control will not be affected. such asBThe value deviates from3950The actual temperature is25°Measured out as24.8°If you set the control temperature to24.8°Then the board will stabilize at the measuring temperature.24.8°The same is true.25°On the other hand, that is to say, the actual temperature corresponding to the measured temperature remains unchanged. The most frightening thing about temperature control is that if you set a temperature, the measured temperature does not change, but the actual temperature changes. When the actual probe B value is 3950, the absolute measurement error is less than 0.1 without considering the initial error of the probe itself.

    NTCThe sensor should be installed in the controlled object, and the installation is exquisite.NTCIt is best to bury it in the controlled object ifNTCExposed to air, the temperature of measurement is also affected by air temperature.NTCIt is best to contact the object in all directions. If the contact is not good, the temperature control is not only uncertain, but also the heat conduction time is too long, the temperature may not be stable. The best way is to punch holes on objects.ABGlue handleNTCBuried in the hole. NTC can not be installed directly on TEC. It should be kept at a certain distance.

    3About serial port,setting temperature,Monitoring temperature summons information

    If your computer has a serial port, you only need to make a serial port line (we sell it) and even the computer. Use the super terminal software that the computer comes with. If your computer does not have a serial port, you need to buy another one.USBThe serial port can be transferred.

     

     

    The instructions have detailed introduction of serial port operation. Serial port is the most basic and the most common way of industrial communication. It doesn't matter if you don't know the serial port.

    When the serial port is connected to normal, the super terminal will continuously output the current measurement temperature and set the temperature.TECUsage and other information. At this point, you can modify the setting temperature through the super terminal.

     

     

    Customers can also tell sellers to set a default factory temperature.

    4About interface

    Detailed instructions, serial port andNTCInterface use2510Terminals, manufacturers will be equipped with interfaces and pins, no need to buy separately.

     

    5About instructions

    Send customers through Wangwang.

    6, about temperature control accuracy, temperature control stability, and accuracy.

     

    Temp AccuracyIt refers to the minimum effective temperature resolution, such as 0.1, 0.01, and 0.001, that can be achieved in the control of the temperature control system. The accuracy of temperature measurement is higher than or equal to the accuracy of temperature control.The accuracy of temperature control also represents the stability of temperature control.The temperature control accuracy of 0.1, that is, the temperature of the controlled object of the normal system can be stabilized within the set value of + - 0.1.Generally speaking, for the temperature control system, the most important parameter is the accuracy of temperature control.Accuracy of temperature measurementIt represents the error between the measured temperature and the absolute true temperature in the physical sense, which is not important to the general system, because if the measured temperature is 25 degrees and the absolute true temperature is 24.5 degrees, then if the object is stable at 25 degrees, it is right. The image is also stable at 24.5 degrees of real temperature. It doesn't matter what the real temperature is (for example, in laser applications, it's about tuning to find the best temperature to get the best output). However, high accuracy of temperature measurement is also beneficial. First, some applications may require high accuracy (for example, to achieve a certain temperature scene, to measure other characteristics of the object). Second, high accuracy can achieve board interchangeability, that is, the same controlled object, even if changed. The temperature control board can only be set to the original setting value without having to find the best temperature again.

    Price does not include tax. If you need VAT invoice, add more.17%. Generally, taxpayers can only issue 17-point invoices, special VAT invoices (detailed invoice information is required), and ordinary VAT invoices (payable) are all 17-point invoices.

    This product provides two years warranty and freight costs.
