Overview
GDJW-800D high and low temperature alternating test chamber is produced by ZKHS, which is suitable for the performance detection of aviation, aerospace products, information electronics, Instruments, materials, electricians, electronic products and various electronic element gas parts in high and low temperature environment. The box body is processed and formed by numerical control machine tool, with beautiful appearance and easy operation.
Features
1. The box body is processed and formed by numerical control machine tool, which is beautiful and easy to operate.
2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate, and the shell is sprayed with A3 steel plate to improve the appearance texture and cleanliness.
3. Large observation window with lighting, embedded tempered Glass, easy to clearly observe the situation inside the box.
4. The left side of the box is equipped with a 50mm diameter test hole, which supports an external test power cord or signal cable.
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 to avoid human touch to change the temperature value.
7. With P.I.D automatic calculation function, accurate and stable temperature control.
8. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit.
9. The refrigeration system is designed with a unit or binary cryogenic loop system.
10. Adopt a multi-wing blower with strong air circulation to ensure uniform temperature distribution.
11. The air circulation design meets the test standards, and the temperature stabilizes quickly at the moment of opening the door.
12. The heating and cooling systems are independent, reducing testing costs, increasing lifespan, and reducing failure rates.
Principle
The test chamber adopts the original French "Taikang" fully enclosed Compressor unit and unit or binary low temperature circuit design through the refrigeration system, combined with the strong circulation air path of the multi-wing blower, to achieve rapid temperature rise and fall. The temperature control adopts P.I.D automatic calculation and 7.0 inch Touchscreen instrument to ensure accurate and stable temperature. The box structure is optimized, the liner is stainless steel mirror plate, and the shell is sprayed with plastic to provide a uniform temperature environment.
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. Set the test parameters through the 7.0-inch large-screen Touchscreen temperature and humidity control instrument, including temperature range, time, etc.
3. Start the device, and the system automatically performs P.I.D calculation and temperature control.
4. Use the observation window to monitor the conditions inside the box, and connect external circuits through test holes if necessary.
5. After the test, turn off the device and disconnect the power supply.
Notice
- Operating Environment Temperature should be maintained at 5 ℃~ 30 ℃, humidity ≤ 85% R.H.
Avoid opening and closing doors frequently to reduce temperature fluctuations.
Regularly check the safety protection devices, such as leakage, short circuit, over-temperature and other protection functions.
- Power frequency stability to prevent overload or overcurrent.
- Pay attention to the cleaning of the box during maintenance to avoid damage to the stainless steel liner and shell.
Do not touch high-temperature parts during operation to prevent burns.
