Overview
HZAOC GDJS-225B 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 also be used for storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the liner is SUS304B stainless steel, the outer wall is Cold rolled steel plate sprayed, and the insulation layer is ultra-fine Glass cotton.
2. The door is sealed with double-decked silicone rubber, and the observation window is a multi-layer conductive film tempered hollow Glass and equipped with frost-proof heating wire and lighting.
3. Equipped with φ 50mm test hole, using high and low temperature resistant silicone rubber low foam stopper.
4. Adopt French "Taikang" fully enclosed Compressor, use R404A environmentally friendly refrigerant, and the refrigeration system is equipped with multiple safety protections.
5. The heater adopts porcelain frame nickel-chrome wire electric heater, and the humidification adopts steam boiler electric heating method, all of which are equipped with anti-dry burning and other safety devices.
6. High Accuracy Digital Temperature and Humidity Controller for Smooth and Accurate Control.
7. The control system is equipped with multiple safety protections such as phase loss, over-temperature, and leakage, as well as independent over-temperature protectors.
8. The electrical system is equipped with an interlock device to ensure that the heating and humidification system cannot be started when the fan is not started or overloaded.
Principle
The test chamber adjusts the temperature and humidity of the air in the working room through the evaporator, electric heater, humidifier and fan in the air conditioning cabinet. The temperature control is realized by the refrigeration system (Compressor, evaporative condenser) and the electric heater controlled by PID; the humidity control is realized by the electric heating humidifier controlled by PID. The upper air supply and lower air return mode is used to ensure the uniform temperature and humidity in the box. The control system monitors and adjusts the output in real time to simulate the required temperature and humidity environmental 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

Steps
The specific operation steps are not provided in the data
Notice
* Equipment must operate at 380V +/- 10% Power supply voltage.
* Make sure the phase sequence is correct before running to avoid phase sequence error protection triggering.
Pay attention to observe the water level to prevent the humidifier from dry burning.
The equipment is equipped with an interlock device. If the circulating fan is not started normally, the heating and humidification system will not work.
If the main controller fails, the independent over-temperature protector will cut off the heating power supply, and the fault needs to be checked at this time.
* When using the test hole, attention should be paid to the sealing and insulation efficiency of the stopper.
Regularly check the effectiveness of system protection devices (such as high voltage control, overvoltage, overload protection).
