Overview
HZAOC GDJS-500E High and Low Temperature Alternating Damping heat testing 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 as an adaptability test equipment for storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is SUS304B stainless steel plate, the outer side is Cold rolled steel plate sprayed, and the thermal insulation material is ultra-fine Glass thermal insulation cotton.
2. The door is made of double-decked silicone rubber sealing material, which has good sealing performance.
3. The observation window is a multi-layer conductive film tempered hollow Glass, with built-in special heating wire anti-frost and lighting.
4. The side of the box is equipped with a test hole with a silicone rubber stopper, which has both thermal insulation efficiency.
5. The air supply method adopts upper air supply and lower return air.
6. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor unit and uses R404A environmentally friendly refrigerant.
7. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertia and long service life.
8. Adopt steam boiler electric heating and humidification method, with water level control and anti-dry burning device.
9. The control system adopts High Accuracy Digital Temperature and Humidity Controller for accurate and stable control.
10. Equipped with comprehensive safety protection measures, including multiple protections such as phase loss, over-temperature, and leakage.
11. Equipped with an independent over-temperature protector, it can still protect the safety of the equipment in the event of a main controller failure.
Principle
The test chamber adjusts the environment in the working room through evaporators, electric heaters, humidifiers, fans and other equipment in the air conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle to achieve rapid cooling and temperature control through Compressor, condenser, evaporator and other components. The heating and humidification systems generate heat and humidity through PID-controlled electric heaters and steam boilers respectively, and are precisely adjusted by the High Accuracy Temperature and Humidity Controller according to the feedback of the Sensor to realize the set temperature and humidity Linear dispersion and alternating test.
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
Steps
Connect 380V +/- 10% power supply.
2. Set the required Temperature range (-70~ 150 ℃), Humidity range (30~ 98% RH), lifting temperature rate and timing time (0~ 999h) through the function buttons on the operation panel.
3. Place the sample in the studio.
4. Start the equipment, and after the circulating fan is started, the heating and humidification system can work.
5. Observe the test process through the observation window and lighting.
6. After the test, remove the sample and turn off the power of the equipment.
Notice
• Power supply voltage meets 380V +/- 10% requirement before running the equipment.
The equipment is equipped with an interlock device, and the heating and humidification system cannot be started when the circulating fan is not started or overloaded.
• When using the test hole, pay attention to the sealing and insulation of the stopper.
• During the operation of the equipment, do not open the box door frequently to avoid affecting the stability of temperature and humidity.
• Regularly check the water level control device and heater anti-dry burning device to ensure that the humidification system works normally.
• Pay attention to the status of various protection indicators when the equipment is running, and deal with the fault alarm in time.
• During maintenance, please disconnect the main power supply of the equipment first.
