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 box.
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 and avoid dead ends.
7. Adopt enlarged observation window, 4 layers of tempered Glass, wide field of vision.
8. The comprehensive protection system includes 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 of the instrument, and ensuring long-term accurate and stable operation.
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. Open the instrument and set the program Linear dispersion through the large color LCD touch interface of the controller.
3. Adjust the temperature and humidity parameters as needed, and the controller automatically calculates the control.
4. Start the test, the instrument runs automatically, and monitors temperature and humidity changes.
5. After the test is completed, turn off the instrument and disconnect the power supply.
Notice
• The working environment temperature should be kept at 0~ 30 ℃, and the performance guarantee environment is 5~ 25 ℃.
• Use environment requirements: Miscellaneous items cannot be placed within 60CM.
• Pay attention to protection functions such as power overload and leakage, and automatically shut down and display faults when abnormal.
• Ensure proper operation of Compressors and Miscellaneous components to avoid over-temperature or humidity deviations.
