Overview
HZAOC GDJW-500A high and low temperature alternating test chamber is suitable for 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 of electronic components. The box adopts an overall structure, the inner side is stainless steel plate, the outer side is sprayed Cold rolled steel plate, and the thermal insulation material is ultra-fine Glass thermal insulation cotton.
Features
1. The box adopts the overall structure, the inner side is 1.0mm SUS304B stainless steel plate, the outer side is 1.0mm Cold rolled steel plate sprayed, and the thermal insulation material is ultra-fine Glass thermal insulation cotton.
2. The door sealing is made of double-decked silicone rubber sealing material, and the observation window is a multi-layer conductive film tempered hollow Glass with built-in heating wire to prevent frost 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. The control system adopts LCD Touchscreen temperature and humidity controller and Schneider electrical components, and supports full Chinese menu operation.
5. With a variety of safety protection measures, including phase loss protection, over-temperature protection, power-off protection, etc.
6. Support setting and program operation, can store 120 sets of programs, up to 99 steps each, and support power failure recovery function.
Principle
The test chamber generates heat through the heater, and the PID control mode is used to adjust the temperature through the solid state relay to achieve stable control. The cooling system uses the shunt method to adjust the cooling capacity, and the air supply mode is the upper supply air and the lower return air to ensure the uniform temperature in the box. The temperature transducer is placed in a trend to monitor the temperature change in real time, and the control system automatically adjusts the operation of the heating and cooling system according to the set parameters.
Applications
Electrical, electronic products, components, parts and materials high and low temperature adaptability test, temperature gradual change test, stress screening test
Steps
1. Set the temperature parameters in the controller or select the preset program.
2. Start the equipment and the system automatically runs the heating or cooling process.
3. Monitor temperature data and equipment status in real time.
4. After the test is completed, stop the equipment according to the program.
Notice
• Power frequency must be stable at 380V +/- 10% when the equipment is running.
• Regularly check the safety protection system, such as whether the over-temperature protector is normal.
• Avoid operating the cooling and heating system when the fan is not started or overloaded.
• Pay attention to the thermal insulation efficiency of the sealing plug when using the test hole.
• In the event of a fault, refer to the fault number displayed by the controller for troubleshooting.
