The PV wet test chamber is specifically designed for aging tests of photovoltaic modules, photovoltaic glass, thin-film modules, and solar cells. It simulates the effects of repeated temperature changes to evaluate the fatigue and thermal stress failures that components may experience over time. This testing is crucial in ensuring the long-term reliability and performance of solar products under various environmental conditions.
The controller of the PV wet test chamber features a 7-inch true-color touch screen (North Carolina model), offering an intuitive and user-friendly interface. Users can easily set temperature and time parameters without needing to manually input compressor or other command signals. The controller supports both Chinese and English language options, allowing users to monitor real-time performance through dynamic running curves displayed on the screen.
With a capacity of 1000 program memories, each containing up to 1000 segments and 100 cycles, the system also supports linking up to 10 different programs together. It provides clear feedback on the current program number, execution count, remaining time, and cycle progress. The controller also displays total operating time, making it easy to track and manage test sessions.
Equipped with PID auto-tuning and fuzzy control technology, the system ensures precise temperature regulation throughout the testing process. Additionally, it offers data acquisition, export, and graphical display functions, enabling users to analyze and document test results efficiently.
Note: The controller (also known as the "control unit") is the main device responsible for managing the wiring of the main or control circuits, adjusting resistance values, and controlling motor operations such as starting, speed adjustment, braking, and reversing. It consists of key components like the program counter, instruction register, instruction decoder, timing generator, and operation controller. As the "decision-making body" of the system, it coordinates and directs all operations within the computer or testing equipment.
