3. Large observation window with lighting, embedded tempered Glass, clear observation of the situation in the box.
4. The left side of the box is equipped with a 50mm diameter test hole, which is convenient for external test power or signal wires.
5. The temperature control adopts a 7.0-inch large-screen Touchscreen temperature and humidity control instrument, and the operation setting is simple.
6. The controller has a locking function and P.I.D automatic calculation, resulting in accurate and stable temperature control.
7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit, and the refrigeration system adopts a unit or binary low temperature circuit design.
8. The multi-wing blower has strong air circulation, uniform temperature distribution, and the air circulation design meets the test standards.
9. The heating and cooling systems are independent, effectively reducing testing costs, increasing lifespan, and reducing failure rates.
10. Safety protection includes leakage, short circuit, overheating, motor overheating, Compressor overvoltage, overload, overcurrent protection.
Principle
The test chamber realizes high and low temperature environment simulation through heating system and refrigeration system. The heating system adopts nickel-chromium alloy electric heating heater to work independently, and the refrigeration system adopts French "Taikang" fully enclosed Air-Cooled compression refrigeration method, combined with multi-wing blower circulation air path, to ensure uniform temperature distribution and rapid stability in the test area. The control system uses P.I.D automatic calculation to correct temperature changes in real time to achieve accurate temperature control.
Applications
Aviation, Aerospace Products, Information Electronics, Instruments, Materials, Electrical, Electronic Products, Various Electronic Components
Standards
G B 2423.1 - 2008 Test A "High Temperature Test Method", G B 2423.2 - 2008 Test B "Low Temperature Test Method", GJB150A.3, GJB150A.4
Steps
1. Connect the power supply to ensure that the voltage is AC280V +/- 10% or AC380V +/- 10%, 50Hz three-phase five-wire system.
2. Enter the test conditions and parameters through the large-screen Touchscreen temperature and humidity control instrument.
3. The controller locks the setting value to avoid accidental touch changes.
4. Start the device, and the system automatically performs P.I.D calculations and temperature control.
5. Use the observation window to monitor the test status in the box, and connect external cables through the test hole if necessary.
6. After the test is completed, turn off the device and disconnect the power supply.
Notice
• Operating Environment Temperature should be 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
• Power frequency compliance to avoid overload or short circuit.
• Regularly check safety protection devices, such as leakage, over-temperature protection, etc.
• Avoid touching high or low temperature parts during operation to prevent burns or frostbite.
• Keep the cabinet clean and maintain the refrigeration and circulation system regularly.
Do not open the door frequently during the test, so as not to affect the temperature stability and test accuracy.
