Overview

The product application meets the standards: IEC61215-MQT10、MQT11、MQT16、MQT20、MQT22IEC61730-MST26、MST34、MST51、MST52、IEC62782 This includes providing stable DC power, current recording, temperature recording, and temperature control functions. By controlling the opening of the DC power supply through temperature, it can monitor multiple currents and temperatures in real-time for a long time. Used in conjunction with high and low temperature circulation boxes, it can monitor the conductivity of internal circuits of multiple components. Assess the fatigue resistance of materials, the rationality of lamination processes, and the stability of welding quality of solar cell modules in high and low temperature alternating environments.

Product Details

1) Adopting a special heat dissipation channel to dissipate heat, it avoids the phenomenon of high temperature caused by long-term high current heating, ensuring the long-term uninterrupted operation of the equipment;

2)Adopting a stable constant current power supply to avoid overload and power outage caused by unstable internal resistance of components in high and low temperature alternating situations;

3)The single current control function required in the standard has been improved, and a multi-channel current recording control function has been adopted to achieve individual temperature control for each component, ensuring that each component can meet the experimental conditions while monitoring the temperature performance of each component under high and low temperature alternation;

4)Test data: Supports standard SECS/GEM protocol and RJ45 interface, providing open permissions and parameters. Equipped with a mobile storage interface or communication interface (connected to a computer), the data collector can continuously record data for more than 1 year, and has functions such as data storage, deletion, save as, curve viewing, and historical data query;

5)Equipped with 5N weights, apply tension during power on process;

6)Good human-machine interface, using high-quality industrial control computers to ensure long-term stable operation of the equipment. Data recording: The data content includes a 20 digit serial number (test sample serial code) with the year, month, day, and collection time.
