What is the role of the customized non-standard power supply customized module (factory?(3)

Input protection circuit General dc 48V input power supply module 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, customized non-standard 48V input power supply customized module (factory 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 distributed power supply mode has the advantages of energy saving, reliability, high efficiency, economy and easy maintenance. It has been gradually adopted by large-scale computers, communication equipment, aerospace, industrial control and other systems, and is also the most ideal power supply method for low-voltage power supply (3.3V) of ultra-high-speed integrated circuits. In high-power occasions, such as electroplating, electrolytic power supply, electric locomotive traction power supply, intermediate frequency induction heating power supply, motor drive power supply and other fields also have broad application prospects.

In order to prevent the transient high voltage damage of the dc 48V input power supply module 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).
