Overview
GDJW-500C 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 components in high and low temperature environments. The box body is processed and formed by numerical control machine tools, 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. Appearance has good texture and high 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 can be used for external test power or signal wires.
5. The temperature control adopts a 7.0-inch large-screen Touchscreen temperature and humidity control instrument, which has simple operation settings and a locking function.
6. With P.I.D automatic calculation function, the temperature control is accurate and stable.
7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit, and the refrigeration system adopts the unit or binary low temperature circuit system design.
8. The multi-wing blower is used for strong air supply circulation, and the temperature distribution is uniform. The air circulation design makes the temperature return to stability at the moment of opening the door faster.
9. The heating and cooling systems are fully independent, effectively reducing testing costs, increasing lifespan, and reducing failure rates.
Principle
The test chamber is cooled by the original French "Taikang" fully enclosed Compressor unit and unit or binary low temperature circuit system through the refrigeration system, and the heating system is heated by a fully independent nickel-chromium alloy electric heating heater. The temperature control adopts the P.I.D automatic calculation function, which is precisely adjusted by the large-screen Touchscreen temperature and humidity control instrument to ensure the temperature is stable. The air circuit circulation system adopts a multi-wing blower to strongly supply air to avoid dead ends and make the temperature in the test area evenly distributed.
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
Connect the power supply and ensure that the voltage is AC280V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire.
2. Touchscreen temperature and humidity control instrument to set test conditions, such as temperature range and time.
3. Start the device, and the system automatically performs P.I.D calculation and temperature control.
4. Use observation windows and lighting to monitor the conditions inside the box.
5. After the test is completed, turn off the device and disconnect the power supply.
Notice
• Operating Environment Temperature should be between 5 ° C and 30 ° C, humidity should not exceed 85% R.H.
• Avoid touching the controller artificially to prevent changing the set temperature value.
• Regularly check the safety protection device, including leakage, short circuit, overtemperature, motor overheating, Compressor overvoltage, overload, overcurrent protection.
• Ensure that the test holes are used correctly to avoid affecting the test accuracy.
When the equipment is running, do not open the door frequently to maintain a stable temperature.
