Serbia There are three elements in the procurement of 24V power supply(2)
input protection circuit
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).
Noise pollution has always been a major problem for manufacturers. In the early days, machinery and equipment would generate a lot of noise during work, which would affect the health of employees. According to the senior human resources department, it is very difficult to recruit workers at the moment. With the rise of Internet recruiting, it is easier for people to find jobs, but we are reluctant to work in production. If businesses cannot address noise pollution, they may not even find workers. After all, people these days take their health very seriously.
2. Insulation cannot be ignored.
The high-voltage power module will generate a very high voltage during operation. If someone touches it, the consequences are unimaginable. In order to ensure the safety of employees and avoid safety risks, it is necessary to understand the insulation when purchasing high-voltage power supplies. Only by ensuring that the insulation is good enough, can some unnecessary troubles be avoided.
