What is the role of the manufacturer?(3)

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.

Input protection circuit General supplier supply products use built-in filters, which can meet the requirements of general Marine boost voltage power supply applications. If a more demanding power system is required, manufacturer the input filter network should be added. Either LC or π can be used but care should be taken to choose a smaller inductance and larger capacitance.

In order to prevent the transient high voltage damage of the supplier supply, it is recommended that the user connect the transient absorption diode to the input terminal, and cooperate with the fuse to ensure that the module is within the safe input voltage range. In order to reduce the common mode noise, Y (Cy) can be increased and several capacitors nf high frequency capacitors are generally selected. R is a fuse, D is a protection diode, and D is a transient absorption diode (P6KE series).
