What is the role of the high voltage input module power supply?(3)

Input protection circuit General 48V input power supply supply products use built-in filters, which can meet the requirements of general 48V input power supply applications. If a more demanding power system is required, high voltage input 48V input power supply supply 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.

●The design is simple. Power is available with just one power module, with a few discrete components. ● Shorten the development cycle. The module power supply generally has a variety of input and output options. Users can also repeatedly stack or cross stack to form a building block combined power supply to achieve multiple input and output, which greatly reduces the prototype development time.
●Change is flexible. If the product design needs to be changed, simply convert or parallel another suitable power module.

In order to prevent the transient high voltage damage of the 48V input 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).
