The function of rainproof power supply:
1. Moisture-proof and waterproof
Outdoors is a stable environment different from indoors. Due to the influence of various weather factors such as heavy rain and rain, so that the light boxes and LED letters can also operate in the rain, the outdoor power supply is required to have the most basic moisture-proof and waterproof functions.
2. Dustproof
Dust and dust are not as visible to the naked eye as rain, but they exist all the time in nature, and have a great impact on outdoor switching power supplies. They can easily corrode the internal components of the rainproof power supply, resulting in damage to the power supply and shortened life. short.
3. Anti-salt spray
After a sample survey of users in coastal areas such as Hainan, Shenzhen, and Fujian, the results were obtained: the damage rate of outdoor rainproof power supplies in these coastal areas is much higher than that in other inland areas, and the average life expectancy is also much shorter. Take the rainproof power supply with a mid-range price on the market as an example. Its damage rate is about 2% in other areas after one and a half years of use. The damage rate in Shenzhen and other coastal and typhoon-prone areas increases to 10%. The rainproof power supply didn't even last less than three months. This is the scary thing about salt spray. Especially in areas surrounded by the sea, the concentration of salt mist in the air is very high, which can quickly corrode the circuit and cause huge damage to the rainproof power supply body.
