Overview
HZAOC GDJW-50C 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 the overall structure, the inner side is 1.0mm SUS304B stainless steel plate, the outer side is 1.0mm Cold rolled steel plate spraying, and the thermal insulation material is ultra-fine Glass thermal insulation cotton.
Features
1. The box structure is strong, the inner stainless steel, the outer spray steel plate, excellent thermal insulation performance.
2. The door is made of double-decked silicone rubber sealing material to ensure sealing.
3. The observation window is a multi-layer conductive film tempered hollow Glass with built-in heating wire to prevent frost and lighting.
4. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
5. The control system adopts LCD Touchscreen temperature and humidity controller and Schneider electrical components, which is easy to operate.
6. Equipped with a variety of safety protection functions, including phase loss, over-temperature, and overload protection.
Principle
The test chamber realizes temperature control through heating and cooling system, the heater adopts PID signal through solid state relay control, and the cooling capacity adjustment adopts shunt method. The control system adopts continuous PID control mode to support fixed value and program operation, the temperature transducer is placed in the trend, and the air supply mode is upper supply air and lower return air to ensure temperature uniformity and stability.
Applications
Electrical and electronic products, components, parts and materials adaptability test, stress screening test
Steps
1. Use the LCD Touchscreen controller for full Chinese menu operation.
2. Set the temperature program, which can store and call multiple process Linear dispersion.
3. Select the running mode as fixed value or program running.
4. Start the device and monitor the temperature, time and other parameters displayed in real time.
5. In the event of a failure, locate the cause according to the fault number displayed by the controller.
Notice
• Power frequency is 380V +/- 10% when the equipment is running.
• When the circulating fan is not started or overloaded, the refrigeration unit and heating system cannot be started.
• Regularly check safety protection devices, such as over-temperature protectors, high voltage controls, etc.
• When using the test hole, pay attention to the thermal insulation efficiency of the stopper.
• Avoid running in extreme temperatures for long periods of time to prevent equipment overload.
