Customized Temperature Control Equipment

Semiconductor TEC temperature controllers operate based on the Peltier effect. When an electric current passes through a circuit composed of two different semiconductor materials, heat absorption or release occurs at the junctions. Simply put, by reversing the direction of the current, the hot and cold sides of the semiconductor module can be interchanged, enabling bidirectional temperature regulation. This non-mechanical cooling method, compared to traditional compressor-based refrigeration, avoids issues such as refrigerant pollution and mechanical vibration, offering inherent advantages like high precision, noiseless operation, long lifespan, and compact size. It is particularly suitable for scientific research and industrial applications with stringent environmental requirements.

II. Core Technologies and Functional Features

1. High-Precision PID Intelligent Control

Semiconductor TEC temperature controllers are equipped with advanced PID (Proportional-Integral-Derivative) control algorithms, dynamically adjusting output power by monitoring real-time temperature feedback data. For example, when the temperature approaches the set value, the system automatically reduces the adjustment amplitude to avoid overshooting, achieving ultra-high temperature control accuracy of ±0.1°C. This intelligent stepless temperature control technology can precisely match temperature-sensitive applications such as laser devices and medical equipment.

2. Bidirectional Temperature Control and Wide-Range Adjustment

The device supports both heating and cooling modes, with a temperature control range typically spanning from -40°C to 200°C, meeting diverse needs from low-temperature environment simulation to high-temperature stability testing. Whether it is low-temperature performance testing of semiconductor chips or constant temperature control in chemical reactions, the system can respond quickly and maintain stable temperatures.

3. Multiple Safety Protection Mechanisms

To ensure equipment and experimental safety, TEC temperature controllers integrate overcurrent, overvoltage, overtemperature, and undertemperature protection circuits. In the event of abnormal current, voltage fluctuations, or temperature exceeding limits, the system immediately initiates protection procedures, automatically cutting off power or adjusting output to prevent equipment damage and experimental accidents.

4. Modular and Customized Design

- Multi-Channel Modularity: Offers 1 to 24 optional temperature control modules, allowing research teams to flexibly configure according to experimental scale, meeting the needs of multi-sample simultaneous testing.

- Customized Services: Supports customization of parameters such as temperature control range, cooling capacity, and platform area, providing tailored solutions for scenarios like vacuum testing and special-sized equipment.

5. Digital Communication Interfaces

Equipped with communication interfaces such as RS232 and RS485, compatible with common temperature sensors like NTC, PT100, and PT1000, and open communication protocols. Users can remotely monitor and control the device via computers or automated systems, enabling functions such as data acquisition and temperature curve recording, thereby enhancing the intelligence level of experiments and production.
