Feb 26, 2025
Condition one: environmental condition
1. Temperature: 15 ℃~35 ℃;
2. Relative humidity: not exceeding 85%;
3. Atmospheric pressure: 80kPa~106kPa
4. There is no strong vibration or corrosive gas around;
5. No direct sunlight exposure or direct radiation from other cold or heat sources;
6. There is no strong airflow around, and when the surrounding air needs to be forced to flow, the airflow should not be directly blown onto the equipment.
7.No magnetic field surrounding of the test chamber that may interference control circuit.
8.There is no high concentration of dust and corrosive substances around.
Condition two: Power supply condition
1. AC Voltage: 220V ± 22V or 380V ± 38V;
2. Frequency: 50Hz ± 0.5Hz.
Usage Conditions three: Water Supply Conditions
It is recommended to use tap water or circulating water that meets the following conditions:
1.Water Temperature: Not exceeding 30℃;
2.Water Pressure: 0.1MPa to 0.3MPa;
3.Water Quality: Complies with industrial water standards.
Usage Conditions four: load for test chamber
The test chamber load must simultaneously meet the following conditions:
1. Total Mass of Load: The mass of the load per cubic meter of workspace volume should not exceed 80 kg;
2. Total Volume of Load: The total volume of the load should not exceed 1/5 of the workspace volume;
3. Load Placement: On any cross-section perpendicular to the main airflow direction, the total area of the load should not exceed 1/3 of the workspace cross-sectional area. The load must not obstruct airflow.
