What is the role of the supplier?(3)

Input protection circuit General 24 v Marine boost voltage power supply supply products use built-in filters, which can meet the requirements of general Marine boost voltage 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.

(9) For the high-voltage module power supply, do not touch the high-voltage dangerous area during use and within 10 minutes after the power outage.
(10) Purchasing principle of module power supply: Generally, switching power supply should be selected for larger power, and linear power supply should be selected for smaller power.
(11) The module power supply cannot be forcibly dismantled, and it will be damaged if it is forcibly dismantled.

In order to prevent the transient high voltage damage of the 24 v Marine boost voltage 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).
