What kind of 48V input 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.

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.

48V input LED advertising screen power supplyFour: Electrolytic and ceramic capacitors

The distributed power supply mode has the advantages of energy saving, reliability, high efficiency, economy and easy maintenance. It has been gradually adopted by large-scale computers, communication equipment, aerospace, industrial control and other systems, and is also the most ideal power supply method for low-voltage power supply (3.3V) of ultra-high-speed integrated circuits. In high-power occasions, such as electroplating, electrolytic power supply, electric locomotive traction power supply, intermediate frequency induction heating power supply, motor drive power supply and other fields also have broad application prospects.

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.
