What is the role of the input?(3)
Input protection circuit General military module Marine boost voltage power supply 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, input 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 military module Marine boost voltage power supply 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).
