What kind of Marine boost/buck voltage 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
power source is realized through the power transfer switch.
Modern UPS generally adopts pulse width modulation technology and modern power electronic devices such as power MOSFET, IGBT, etc., the noise of power supply can be reduced, and the efficiency and reliability can be improved. The introduction of microprocessor software and hardware technology can realize intelligent management of UPS, remote maintenance and remote diagnosis.
The maximum capacity of the online UPS can be made to 600kVA. The development of ultra-small UPS is also very rapid, and there are already 0.5kVA, lVA, 2kVA, 3kVA and other products of various specifications.
Determine power, temperature and transformer. The transformer is responsible for the AC-DC LED advertising screen power supply, and the energy overload will saturate.
Marine boost/buck voltage LED advertising screen power supplyFour: Electrolytic and ceramic capacitors
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.
