Overview
HZAOC GDJS-010A 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, and the observation window is made of multi-layer conductive film tempered hollow Glass and equipped with frost-proof heating wire and lighting.
3. Equipped with test holes with silicone rubber plugs for both thermal insulation performance.
4. Low temperature refrigeration adopts French "Taikang" fully enclosed Compressor and uses R404A environmentally friendly refrigerant.
5. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
6. Adopt steam boiler electric heating and humidification method, equipped with water level control and anti-dry burning device.
7. The control system adopts High Accuracy Digital Temperature and Humidity Controller, which does not drift for long-term operation.
8. It is equipped with an independent over-temperature protector and multiple safety measures, such as phase loss, over-temperature, and leakage protection.
9. The electrical control 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 box through evaporators, electric heaters, humidifiers, fans and other equipment in the air conditioning cabinet. The temperature control uses PID signals to control the heater through solid state relays, and the humidity control uses steam boiler electric heating and humidification and is controlled by PID. The refrigeration system uses Compressor refrigeration, and the cooling capacity is adjusted by shunt method to achieve a Temperature range from -20 ° C to 150 ° C and a Humidity range from 30% to 98% RH. The air supply method is upper supply air and lower return air to ensure uniform temperature and humidity.
Applications
Test for moisture resistance and high and low temperature adaptability of electrical and electronic products, components, parts and materials
Standards
The data did not mention specific compliance criteria
Steps
The information does not provide specific operation steps
Notice
* Power supply voltage 380V +/- 10%.
Please familiarize yourself with the power, lighting and function buttons on the operation panel before operation.
Pay attention to the prompt of the fault indicator light and deal with it in time when a fault occurs.
* Ensure that the test hole stopper (made of silicone rubber) is installed correctly to maintain thermal insulation.
The equipment is equipped with an interlocking device. When the circulating fan is not started or overloaded, the heating and humidification system will not be able to start. Please do not force it.
Reliability of system protection devices such as over-temperature protectors is checked regularly.
When maintaining, please note that the refrigerant is R404A environmentally friendly.
