Overview
HZAOC GDJS-100D 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 layer is made of ultra-fine Glass thermal insulation cotton.
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 anti-frost built-in heating wire and lighting.
4. The side of the box is equipped with a test hole with a silicone rubber plug, which has both thermal insulation efficiency.
5. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor and uses R404A environmentally friendly refrigerant.
6. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
7. The humidification system adopts the steam boiler electric heating humidification method, and is equipped with water level control and dry burning prevention devices.
8. The control system adopts High Accuracy Digital Temperature and Humidity Controller, which does not drift for long-term operation.
9. Equipped with multiple safety protection measures, including phase loss, over-temperature, leakage, etc., and equipped with an independent over-temperature protector.
10. The air supply method is the upper air supply and the lower air return, and the temperature sensor is placed in a trend.
Principle
The test chamber adjusts the temperature and humidity of the air in the working room through evaporators, electric heaters, humidifiers and fans in the air conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle to achieve rapid cooling through components such as Compressor, condenser, evaporator, etc. The heating and humidification systems are driven by PID-controlled solid-state relays to precisely adjust the temperature and humidity. The control system monitors and adjusts the environment parameters in real time to achieve the set high and low temperature alternating and humidity cabinet test conditions.
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
The data did not mention specific compliance criteria
Steps
Connect 380V +/- 10% power supply.
2. Set the required Temperature range (-60~ 150 ℃), Humidity range (30~ 98% RH) and timing time (0~ 999h) through the function buttons on the operation panel.
3. Start the equipment and the circulating fan starts running.
4. The equipment automatically controls the operation of the refrigeration, heating and humidification systems according to the settings to achieve constant temperature and humidity changes.
5. During the test, the conditions in the box can be observed through the observation window and lighting.
6. The test stops automatically after reaching the set time, or it can be stopped manually through the operation panel.
Notice
• Power supply voltage 380V +/- 10%.
When starting, ensure that the circulating fan starts normally, otherwise the heating and humidification system will not start due to the interlocking device.
• When using the test hole, pay attention to the sealing and insulation of the stopper.
• The equipment is equipped with a variety of safety protections. If the fault indicator light is on, corresponding problems (such as phase loss, overtemperature, etc.) should be investigated.
When maintaining, please note that the heating and humidification systems are controlled by solid state relays, and repairs must be carried out by professionals.
• The humidification system is equipped with water level control and anti-dry burning devices, and the water level still needs to be checked regularly.
• The refrigeration system uses environmentally friendly refrigerant R404A and has high voltage protection. Non-professionals should not operate the refrigeration circuit.
