Overview
HZAOC GDJS-010C 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, as well as the adaptability test of storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is stainless steel plate, the outer side is sprayed steel plate, 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 to prevent frost 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. Adopt the upper air supply and lower return air mode, and the temperature sensor is placed in a trend.
6. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor 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, which does not drift for long-term operation.
10. The control system is equipped with multiple safety protections such as phase loss, over-temperature, and leakage, as well as independent over-temperature protectors.
Principle
The test chamber adjusts the temperature and humidity of the air in the box 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 through Compressors, condensers, evaporators and other components. The heating and humidification systems generate heat and steam through electric heaters and electric heating humidification pipes respectively. The High Accuracy Temperature and Humidity Controller collects PT100 Sensor signals, and controls the actuators such as solid-state relays through PID operations to achieve accurate and stable control of the temperature and humidity of the environment in the box to simulate the required 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
The information does not provide specific operation steps
Notice
• Equipment needs to operate at 380V +/- 10% Power supply voltage.
• The system is equipped with high voltage control, overvoltage, overload and other protection, and the high voltage meter should be monitored during operation.
• The heating and humidification system start-up is interlocked by the state of the circulating fan, and the fan cannot be started when it is not started or overloaded.
• Before use, ensure that the water level control device and heater anti-dry burning device are normal.
• Please pay attention to the fault indicator light on the panel when operating.
• There is an independent over-temperature protector outside the main controller, but the system Reliability needs to be checked regularly.
