What is the role of the wholesale?(3)


AC-DC power module

(1) After opening the package, it is necessary to carefully check whether the identification of each terminal is in line with the instructions that are brought along with it, and whether it is in line with the requirements of the order contract. If it does not match, you should immediately contact the production or sales unit to discuss how to deal with it.
(2) As the first step of installation, the metal casing of the module power supply must be grounded reliably to ensure safety, but the casing should not be connected to the zero line by mistake.

Input protection circuit General supplier 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, wholesale 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).
