What kind of LED advertising screen power supply will be higher(3)

The core problem of the LED advertising screen power supply is the IC, which is like the brain of the LED advertising screen power supply. The quality of the IC can directly affect the various working parameters of the LED advertising screen power supply.

Distributed Power Supply System
The distributed power supply system uses low-power modules and large-scale control integrated circuits as basic components, and uses the latest theoretical and technological achievements to form a building block-type, intelligent high-power power supply, so that the strong and weak currents are closely combined and the high power is reduced. Components, high-power devices (centralized) development pressure, improve production efficiency.

Three: Transformer components

Determine power, temperature and transformer. The transformer is responsible for the AC-DC LED advertising screen power supply, and the energy overload will saturate.

Electrolytic capacitors, aluminum electrolytic capacitors and monolithic gallbladders, which use sulfuric acid to make the insulating medium, large capacity can carry out smaller volumes for the above, and are marked with a + sign, some are marked with a mark, generally do low cross-linking and side-by-side Circuit filter with larger loss meson, integral aluminum electrolytic capacitor, due to the shortcomings of using special materials, the electrolytic performance is better than ordinary, the preferred frequency, but can not do too much capacity, it can be used to accurately circuits, such as oscillators, or timing circuits.
