Overview
HZAOC GDW-800C low/high temperature test chamber is suitable for the adaptability test of electrical, electronic products, components, parts and materials in high and low temperature environment storage, transportation and use, as well as temperature gradual change test, and stress screening test for electronic components.
Features
1. The box adopts the overall structure, the liner is imported SUS304B stainless steel, the shell is sprayed with Cold rolled steel plate, and the insulation layer is ultra-fine Glass insulation cotton.
2. The door is sealed with double-decked silicone rubber, and the observation window is a multi-layer conductive film tempered hollow Glass, with frost-proof heating wire and lighting.
3. The heater adopts a porcelain frame nickel-chrome wire electric heater, which has little thermal inertia, long service life, and stable and reliable control.
4. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor, the core refrigeration components are imported brands from many countries, and R404A refrigerant is used.
5. Control system adopts High Accuracy Digital Temperature Controller and PT100 Sensor for accurate and stable control.
6. Safety protection system with multiple, including independent over-temperature protector, electrical interlock and phase loss, overvoltage, overload, leakage and other protection.
Principle
The equipment adjusts the temperature of the studio through the evaporator (refrigeration) and electric heater (heating) in the air-conditioning cabinet, and the circulating fan realizes the air circulation of the upper air supply and lower air return to ensure uniform temperature. The temperature sensor is placed in a trend and feeds back the signal to the High Accuracy digital display temperature controller. The temperature controller regulates the operation of the heater and the refrigeration unit by controlling the solid state relay, so as to achieve accurate temperature control and programmed testing.
Applications
Electrical and electronic products, electronic components, parts, materials high and low temperature adaptability test, temperature gradual change test, stress screening test
Standards
GB/T2423.1-2001、GB/T2423.2-2001、GB/T10592-2008、GB/T10589-1989、GB/T11158-1989、IEC68-2-1、IEC68-2-2
Steps
1. Ensure that the equipment is placed in an environment that meets the requirements (room temperature below 28 ° C, well ventilated, and there is nothing within 80 cm around) and connect the AC380V three-phase four-wire power supply.
2. Turn on the power supply through the button on the operation panel, and set the test temperature, time and other parameters as needed.
3. Start the equipment, and after the circulating fan runs, the heating or cooling system starts to work according to the set program.
4. During the test, the conditions in the box can be monitored through the observation window.
5. After the test, the equipment stops running according to the program, the sample is removed, and the power is turned off.
Notice
* Operating Environment Temperature should be between 5 ℃ and 28 ℃, and the average temperature within 24 hours should be less than or equal to 28 ℃.
* Environmental humidity should be ≤ 85%.
* Must use AC380V (+/- 10%)/50HZ three-phase four-wire power supply.
* The operating environment of the equipment should be below 28 degrees and well ventilated.
* No items can be placed within 80 cm of the front, rear, left and right of the equipment placement.
* The equipment is equipped with test holes, please use matching silicone plug sealing when not in use.
* Before running, please confirm that each Safety protection function is normal. If the fault indicator light is on, the fault should be eliminated first.
* Regularly check the sealing strip, heating wire and other wearing parts.
