What is the role of the non-standard customization?(3)

Input protection circuit General control in the on-board DCDC supply products use built-in filters, which can meet the requirements of general 24V input power supply applications. If a more demanding power system is required, non-standard customization 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.

●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.

In order to prevent the transient high voltage damage of the control in the on-board DCDC 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).
