SPECIFICATION

Here is the translation of the text into English:

The step-type temperature and humidity test chamber for display module reliability typically includes working conditions such as temperature range, humidity range, power requirements, and environmental conditions. Below are the typical working conditions of this equipment:

• Standard Working Temperature Range: Typically from -70℃ to +150℃, allowing simulation of extreme high and low temperature environments.

• Temperature Change Rate: The temperature change rate of the test chamber is usually set at 1-5℃/min to ensure smooth temperature transitions that mimic real environmental changes.

• Temperature Fluctuation: The temperature fluctuation is usually required to be no more than ±0.5℃ to ensure precise temperature control.

• Humidity Control Range: Typically from 10% RH to 98% RH, allowing simulation of both low and high humidity conditions as well as extreme humidity environments.

• Humidity Change Rate: The humidity change rate is usually set at 2% RH/min, ensuring smooth humidity transitions without sudden changes that could negatively affect test results.

• Humidity Uniformity: The humidity uniformity is generally required to be within ±3% RH throughout the test chamber.

• Power Type: Typically single-phase or three-phase AC power.

• Power Voltage: Common power voltage is 220V ±10% or 380V ±10%, with a frequency of 50Hz or 60Hz, depending on the equipment specifications.

• Power Capacity: The power capacity requirement depends on the test chamber size and specifications, typically ranging from 3kW to 15kW.

• Air Quality: The test chamber should be operated in an environment with good air quality to prevent dust, smoke, and other pollutants from entering the equipment and affecting its performance.

• Installation Location: The chamber should be installed in a location with good ventilation and no strong vibrations or excessive moisture, away from direct sunlight. Extreme temperatures (either too high or too low) should also be avoided to ensure optimal performance.

• Operating Temperature Range: When operating the equipment, the room temperature should typically be within a normal range (e.g., 20℃ to 25℃) to ensure the safety of operators and optimal equipment performance.

• Equipment Service Life: The equipment should be regularly inspected and maintained according to the manufacturer's operating and maintenance manual to ensure long-term, stable operation.

• Test Cycle: Depending on the required testing items, the test cycle can range from a few hours to several months, depending on the product being tested and the test objectives.

• Temperature and Humidity Control Accuracy: Typically, temperature control accuracy is ±0.5℃, and humidity control accuracy is ±2% RH to ensure environmental stability.

• Safety Protection Measures: The equipment should have safety measures such as overheat protection, overload protection, and leakage protection to ensure safety during operation.

The working conditions of the step-type temperature and humidity test chamber for display module reliability include temperature range, humidity range, power requirements, and environmental conditions. To ensure accurate test results, the equipment needs to operate under strictly controlled environmental conditions. The precision of temperature and humidity control, power requirements, and the operating environment must all meet certain standards and specifications. These conditions are set to simulate various real-world environmental changes, helping assess the stability and reliability of the display module under extreme temperature and humidity conditions.
