General module power products have built-in filters, which can meet the requirements of general power supply applications. If a more demanding power system is required, an input filter network should be added. An LC or π-type network can be used, but care should be taken to choose a smaller inductance and larger capacitance as much as possible.
In order to prevent the transient high voltage of the input power supply from damaging the power supply of the module, it is recommended that the user connect a transient absorption diode at the input end and use it with a fuse to ensure that the module is within a safe input voltage range. In order to reduce common-mode noise, Y (Cy) capacitors can be added, and a few nf high-frequency capacitors are generally selected. R is a fuse, D1 is a protection diode, and D2 is a transient absorption diode (P6KE series).

How to install the Austria AC 48V input power supply so that it can function as a protection switch?

Since the air switch and the leakage switch do not have protective functions, when the 48V input power supply is abnormal, a large number of electrical equipment will be damaged. When these accidents occur, it is only necessary to disconnect the 48V input power supply when the 48V input power supply is abnormal, so as not to damage the electrical equipment.

Austria The three-phase AC power intelligent protector has major electrical fault protection functions such as overvoltage, low voltage, neutral wire disconnection, short circuit, phase loss/opening, etc., and has fault identification, fault indication, voltage before closing, neutral live wire reverse connection, Zero line disconnection, phase loss/phase failure detection, remote monitoring, online parameter modification and software upgrade functions.
