Thailand the switching frequency of the AC-DC switching power supply module?(1)

What is the operating frequency of Thailand the AC-DC switching Marine boost/buck voltage power supply module? What factors need to be considered when choosing an AC-DC switching Marine boost/buck voltage power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.

(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.

Thailand Choosing the switching frequency of the Marine boost/buck voltage power supply does not mean choosing the switching frequency of the Marine boost/buck voltage power supply with a good switching frequency, but the choice is suitable for your own use. Most of the current market is like this. The frequency of the AC-DC switching Marine boost/buck voltage power supply module is between 50K and 135K, and this frequency range can meet most applications. Let's discuss it. Some of the problems that AC-DC encounters when choosing switching frequency:
