The most essential aspect of electronic products is electricity, so power supply has become an extremely important presence. So, in order to cope with various complex and harsh environments, various characteristic new power sources have emerged one after another, and rainproof power sources are one of the more common ones. Rainproof power supply can enable equipment to operate well in various complex and harsh environments. So what are the functions of rainproof power sources?

1, Moisture-proof and waterproof

In the outdoor environment, it is a stable environment different from the indoor environment. Because of the influence of various heavy rain, rainstorm and other weather reasons, in order to make the LED light-emitting words in the light box work in the rain, the outdoor power supply will be required to have the most basic moisture-proof and waterproof functions.

2, Dust prevention

Although the impact of dust, sand, and dust is not as visible as that of rainwater, they are constantly present in nature and have a significant impact on outdoor switching power supplies. They are prone to eroding the internal components of rainproof power supplies, causing power damage and reduced lifespan.

3, Salt spray prevention

1.Install the cable end downwards and vertically upwards. Install two or more screws to ensure

secure installation

2.The PSU should mounting directly on the metal case to get the good cooling, 80% load is recommended without case cooling.
