Overview
GDW-500D low/high temperature test chamber is a ZKHS brand product, suitable for aerospace products, information electronic Instruments, materials, electrical, electronic products and various electronic components in high and low temperature or heat and humidity environment inspection of its performance indicators. The box is processed by numerical control machine tools, beautiful and generous in shape, and adopts no reaction handle, easy to operate.
Features
1. 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.
2. The replenishment tank is placed in the lower right part of the control box body, and has the function of automatic water shortage protection.
3. Large observation window with lighting, embedded tempered Glass, can clearly observe the situation inside the box.
4. The humidification system piping is separated from the control circuit board to avoid water leakage and improve safety.
5. The piping circuit system of the waterway system adopts door opening, which is convenient for maintenance and repair.
6. The box body insulation adopts ultra-fine fiberglass insulation cotton to reduce energy loss.
7. The left side of the box is equipped with a 50mm diameter test hole for external test power or signal wires.
8. The temperature and humidity control instrument adopts a 7.0-inch large screen, which is easy to operate, easy to edit programs, and supports Chinese and English interfaces.
9. With a capacity of 100 sets of programs and 1000 stages of 999 cycles, each time is set to a maximum of 99 hours and 59 minutes.
10. The controller has a screen lock function to avoid human touch shutdown.
11. With RS-232 or RS-485 communication interface, you can design programs and monitor the test process on the computer.
12. With automatic calculation function, it can immediately correct the temperature and humidity change conditions for accurate and stable control.
13. The refrigerator adopts the original French "Taikang" fully enclosed Compressor.
14. The refrigeration system is designed with a unit or binary cryogenic loop system.
15. The multi-wing blower is used for strong air circulation, with uniform temperature and humidity distribution and no dead ends.
16. The air passage circulates the air outlet and return air design, the wind pressure and wind speed meet the test standards, and the temperature and humidity stabilize quickly at the moment of opening the door.
17. The heating, cooling, and humidification systems are completely independent, reducing testing costs, increasing lifespan, and reducing failure rates.
Principle
The low/high temperature test chamber precisely sets and adjusts the environment in the box through the temperature and humidity control instrument. The refrigeration system (original French "Taikang" fully enclosed Compressor) and the heating system (nickel-chromium alloy electric heating heater) are used to achieve temperature changes. The circulation system (multi-wing blower) ensures uniform distribution of temperature and humidity. The controller has an automatic calculation function to correct the temperature and humidity conditions in real time to maintain accurate and stable control.

Steps
1. Connect the power supply to ensure that the voltage is AC280V +/- 10% or AC380V +/- 10%, 50Hz three-phase five-wire system.
2. Open the control instrument and select the Chinese and English operation interface.
3. Edit or select the test program, you can set 100 sets of programs, 1000 segments, 999 cycle steps.
4. Set the temperature range (such as -60 ℃ to 150 ℃) and time parameters (0~ 9999 minutes or hours adjustable).
5. Start the test, and the controller automatically calculates and corrects the temperature and humidity conditions.
6. Monitor the condition of the tank through a large observation window, and replenish the water source if necessary (the replenishment tank has automatic protection).
7. 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 with humidity not exceeding 85% R.H.
• Power frequency compliance to avoid overload or short circuit.
• Regularly check the waterway system and humidification piping to prevent water leakage.
• Use the door opening design for maintenance.
• Avoid touching the controller screen artificially to prevent unexpected downtime.
• Use the test hole on the left side of the box when connecting the external test line.
• Pay attention to safety protection functions, such as leakage, overheating, motor overheating and other protection devices.
• During the heating or cooling process, avoid opening the door frequently to maintain stable temperature and humidity.
