What kind of 主词六替换 will be higher(3)
The core problem of the Marine boost voltage power supply is the IC, which is like the brain of the Marine boost voltage power supply. The quality of the IC can directly affect the various working parameters of the Marine boost voltage power supply.
Three: Transformer components
Determine power, temperature and transformer. The transformer is responsible for the AC-DC Marine boost voltage power supply, and the energy overload will saturate.
(3) Before the installation is completed and the power is turned on, the wiring on each terminal should be checked and checked again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct. Prevent the occurrence of reverse and wrong connections.
(4) For high-power power supplies, there are generally two or more "+" output terminals and "-" output terminals. In fact, they belong to the same output electrode, but for the convenience of user wiring, they are connected together internally.
(5) The module power supply is not allowed to work at full load for a long time. The utilization rate of linear power supply should be controlled within 60%; the utilization rate of switching power supply should be controlled within 80%, otherwise it may cause early artificial failure of module power supply.
主词六替换Four: 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.
