pfc power supply has been widely used in the market, but many friends say they don't know how to buy it. Today, I will bring you how to buy led waterproof power supply.

1. High reliability, especially like the driving power supply of LED street lamps, installed at high altitude, maintenance is inconvenient, and the maintenance cost is also very large.

2. High-efficiency LED is an energy-saving product, and the power of the driving power supply is higher. The structure of the power supply installed in the luminaire is particularly important. Because the luminous power of the LED decreases as the temperature of the LED increases, the heat dissipation of the LED is very important. The power supply is high, the power consumption is low, the heat in the lamp is small, and the temperature rise of the lamp is reduced. It is beneficial to delay the light attenuation of the LED.

3. High power factor: The power factor is the requirement of the power grid for the load. Generally speaking, there are no mandatory indicators for appliances under 70 watts. Although the low-power elements of a single electrical appliance have little impact on the power grid, if we illuminate at night, the same load will be too concentrated, which will cause serious pollution to the power grid.
