What is the role of the wide range input power supply module?(3)

Input protection circuit General wholesale supply products use built-in filters, which can meet the requirements of general Marine boost power supply applications. If a more demanding power system is required, wide range input Marine boost power supply module 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.

Uninterruptible Power Supply (UPS)
An uninterruptible power supply (UPS) is a highly reliable and high-performance power supply necessary for computers, communication systems and occasions that require uninterrupted supply. The AC mains input is converted into DC through the rectifier, part of the energy is charged to the battery pack, and the other part of the energy is transformed into AC through the inverter, and sent to the load through the transfer switch. In order to still provide energy to the load when the inverter fails, another backup

In order to prevent the transient high voltage damage of the wholesale 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).
