3. The refrigeration circulation system adopts the original imported Japanese "Sanyo" brand fully enclosed Compressor (optional French Taikang), the components are imported from Japan, France, the United States, Italy, etc., and the refrigerant is the American environmentally friendly refrigerant (R23A, R404A).
4. Reserve a 50mm diameter test hole on the left side of the test chamber.
5. With Fully Automatic, High Precision System Loop, P.L.C Lock Processing, P.I.D Automatic Calculation Control, High Accuracy and High Stability of Temperature in the Whole Zone.
6. Specially designed air circulation circulation system and sensing system, the trend and return air sensor detection and control to ensure uniform temperature, no dead ends.
7. Adopt enlarged observation window, 4 layers of tempered Glass, wide field of vision.
8. The instrument has a comprehensive protection system, including power overload protection, leakage protection, control loop overload, short circuit protection, Compressor protection, grounding protection, over-temperature protection, alarm sound prompt, and automatically display the fault point and stop when abnormal.
Principle
The equilibrate Conditioning Control System (BTHC) is adopted, and the induction system transmits the actual data in the test chamber to the controller. The controller controls the SSR multi-stage intelligent output and the output power of the equilibrate temperature and humidity system to ensure that the temperature and humidity in the test chamber are fully stable, and It has the function of energy saving, reducing the power used, and ensuring the long-term accurate and stable operation of the instrument.
Applications
Electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, aerospace
Steps
Connect the power supply to ensure that the voltage meets 220V/50HZ, and the allowable value of variation is +/- 10%.
2. Check the surrounding environment of the test chamber to ensure that there are no Miscellaneous items in 60CM.
3. Open the controller and set the program Linear dispersion and parameters through the LCD man-machine interface.
4. Start the equipment and monitor the operating status of the system to ensure stable temperature and humidity.
5. After the test is completed, turn off the device and disconnect the power.
Notice
• The use environment temperature should be maintained at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Miscellaneous items should not be placed in the test chamber 60CM to avoid affecting performance.
• Power supply voltage check before operation to ensure compliance with specifications and avoid overload.
• Pay attention to the instrument protection system, automatically shut down in case of abnormality, and deal with the fault in time.
• Regularly maintain the refrigeration cycle system and sensing system to ensure long-term stable operation.
