Firstly, precautions for the use of large-scale waterproof test box equipment in the factory environment:

1. Temperature range: 15~35 ℃;

2. Relative humidity: 25%~75%;

3. Atmospheric pressure: 86~106KPa (860~1060mbar);

4. Power requirements: AC380 (± 10%) V/50HZ three-phase five wire system;

5. Pre installed capacity: 4 KW equipment usage and overall requirements.
Secondly, when using a large waterproof test box, precautions should be taken:

1. Its equipment is mainly used for testing electrical and electronic products in rainwater environments:

(1) The effectiveness of protective covers or shells to prevent rain infiltration.

(2) Physical damage to the product caused by rain.

(3) The ability of a product to meet its performance requirements during or after exposure to rain in a large waterproof test box.

(4) Is the rainwater drainage system effective.

2. Rain is the sediment formed by liquid water droplets, and it has many characteristics, such as rainfall intensity, droplet size and velocity, physical and chemical properties of rainwater. The various characteristics of rain or their combination will have different impacts on different types of equipment.

The above are all the things to know when using a large waterproof test box.
