What is the protective rating of the UPS power supply? How much do you usually do? What can I do?
Standard to IP + two numbers to express .. For example: IP20, IP30 ..
The first figure indicates the extent of the equipment against the dust, or the extent to which people are protected from harm in a sealed environment. I represents the level of prevention of solid foreign body entry, the highest level is 6;
The second word indicates the degree to which the device is waterproof. P represents the level of water prevention, the highest level is 8.
Such as the degree of protection of the motor IP65, protection class IP55 and so on.
IP protection level definition
IP indicates Ingress Protection. The IP protection class is important for electrical equipment protection, and IP protection systems provide a way to classify products by means of dust, water and anti-collision in electrical equipment and packaging The system was approved by most European countries, and the International Electrotechnical Commission (IEC) was drafted and announced in the IED529 (BS EN 60529: 1992) Outside Package Protection Class (IP code).
The second number:
0 no protection against the outside world or no special protection IP-0
1 to prevent the intrusion of water, vertical drops of water droplets (such as condensate) on the lamp will not cause harmful effects IP-1
2 tilt 15 ° can still prevent the intrusion of water, when the light from the vertical tilt to 15 °, the drip on the lamp will not cause harmful effects IP-2
3 to prevent the spray of water intrusion, rain or against the vertical angle of less than 60 ° in the direction of the water sprayed into the lamp caused damage to IP-3
4 to prevent splash of water intrusion, to prevent the water from splashing into the lighting caused by damage to the IP-4
5 to prevent the injection of water intrusion, to prevent the injection of water from the nozzle into the lamp caused by damage to the IP-5
6 to prevent the invasion of large waves, installed in the deck of the lamps and lanterns to prevent the invasion caused by flood damage caused by IP-6
7 to prevent water intrusion when immersed, the lamp immersed in water for a certain period of time or water pressure below a certain standard to ensure that damage is not due to water damage IP-7
8 to prevent sinking when the water intrusion, the indefinite sinking of the lamp early to specify the state of the water, to ensure that damage is not due to water caused by IP-8
Personal understanding: IP rating is based on the site environment and security requirements to confirm.
Such as IP20 is to prevent human fingers can be extended into the cause of personal injury, but no demand for water.
IP54 is to the dust and water requirements.
