What is the role of the supplier?(3)

The application of module power supply in several aspects
1. Electricity, mainly integrators and meters and smart meters
2. Industrial control, industrial control field
3. Medical, medical equipment, mainly including tire protectors, monitors, etc.
4. Military industry, the military industry is a widely used aspect.

Input protection circuit General supplier 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, supplier 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).
