Overview
HZAOC GDJS-800C high and low temperature alternating damping heat test chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, and can be used for storage, transportation and adaptability tests in high and low temperature environments.
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, the observation window is a multi-layer conductive film tempered hollow Glass, and the built-in special heating wire is frost-proof and lighting.
3. The side of the box is equipped with φ 50mm test hole, the stopper is silicone rubber low foam material, high and low temperature resistance and thermal insulation.
4. The heater adopts a porcelain frame nickel-chrome wire electric heater, which has little thermal inertia, long service life, and stable and reliable control.
5. The humidification system adopts steam boiler electric heating and humidification method, armored electric heating tube, with water level control and anti-dry burning device.
6. The control system adopts LCD Touchscreen Temperature and Humidity Controller, PT100 Temperature Sensor, Solid State Relay Zero Trigger to improve control accuracy.
7. Safety protection measures include phase loss protection, phase sequence error protection, phase voltage uneven protection, fan overload protection, over-temperature power failure protection, leakage protection, etc.
8. Independent over-temperature protectors and interlocking devices ensure equipment safety, and the heating and humidification system cannot be started when the circulating fan is not started or overloaded.
Principle
The test chamber adjusts the temperature and humidity in the working room through the evaporator, electric heater, humidifier, fan and other equipment in the air conditioning cabinet. The temperature transducer is placed in a trend, and the control system precisely controls the heating and humidification through PID signals and solid state relays to achieve a stable temperature and humidity environment.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environment storage adaptability test, transportation adaptability test, use adaptability test
Standards
GB/T2423.3-2001、GB/T5170.5-96、GB/T10586-89
Steps
1. Connect the power supply and ensure that the voltage is AC380V.
2. Start the device through the power button on the operation panel.
3. Use the LCD Touchscreen temperature and humidity controller to set the required temperature and humidity parameters.
4. Start the circulating fan to ensure the normal operation of the system.
5. Turn on the heating or humidification function as required.
6. Monitor the operating status of the equipment and observe the fault indicator.
7. After the test is completed, turn off the heating and humidification system, and then turn off the power.
Notice
Equipment must be operated by professionals to ensure that the Power frequency meets AC380V requirements.
• Before starting the heating and humidification system, confirm that the circulating fan has been started normally and is not overloaded.
• Regularly check safety protection devices, such as over-temperature protectors, leakage protection, etc., to ensure normal function.
• Avoid opening the door while the equipment is running to prevent temperature and humidity fluctuations from affecting the test results.
• When using the test hole, make sure that the stopper sealing is good to prevent air leakage.
• When cleaning and maintaining, disconnect the power supply first to avoid the risk of electric shock.
• In case of failure, stop using it immediately and contact the maintenance staff.
