Q:Industrial 24V switch power outlet "-" is it necessary to connect with the ground?
In theory, each has its own saying, and in engineering practice, some are grounded, others are not. The negative grounding that I touch can improve stability. Products like SIEMENS are basically grounded like this
Q:Why is the power supply of industrial control system mostly DC24V? Why not 17V? 11V?
This is a good option in the power series of standards, standards and made this but after a long time of practice summed up, it will consider a number of factors, the first is a safety voltage on the human body, not all produce the risk of electric shock, second can be regarded as a relatively high safe voltage,
Q:What are the types of power used in industrial UPS? What type of UPS power can take the place of it?
OUTPUT:208/220/230/240V, 50/60Hz1000VA/700WThe AC output voltage is the power frequency 220V voltage, and the device with the power 1000VA can be considered,To replace it, a lot more, Santak's UPS can be, the key is how long you want to spare time, batteries should not buy again?.
Q:PIC microcontroller used in the industrial field, its power supply switching power supply and B0505 isolation module, anti-interference performance is better, feasible?
Definitely better. What about someone else developing this power module? Directly with the switching power supply!
Q:What are the applications of intermediate frequency power supply in industrial field?
Application in welding: intermediate frequency power supply can be used for welding, with fast welding speed, little influence on the surrounding heat, no pickling to remove the advantages of oxidation skin. The utility model can also be used for the after welding and adding (tempering) aspects, so as to greatly improve the work efficiency.The application of intermediate frequency power supply is widespread, and some applications are being developed. With the development of thyristor technology and the continuous accumulation of application experience of intermediate frequency power supply, thyristor medium frequency power supply will have a broader prospect of development
Q:What is the difference between computer power supply and industrial switching power supply? My points run out, thank you enlighten prawns. Thank you
The working conditions of industry are poor, and the temperature is too high. The computer power is slightly lower. Almost anything else
Q:Which brand of industrial switching power is good, including imported, not modular power?.Refuse advertising
Japan LAMBDATaiwan meanwell power switch (MW) MEANMALLShanghai Heng Fu switch power supply (HF)Shanghai Lan Fu switch power supply (LanFu)Chaoyang Power SupplyJinweiyuan powerDa Tong Tong DaJapan Kosovosiemens
Q:Is the switch power supply for industrial instrument power good or transformer good?
Switch power supply for industrial instrument power supply is good or transformer is good. It needs to be determined according to the use.Switching power supply and transformer power supply have their respective advantages and advantages. In the power supply fluctuations or industrial instrumentation is long-term needs of the power for 24 hours, using a transformer power supply is reliable, because it is very durable, not easy to damage. The switching power supply is cheap, low cost, high power efficiency relative to the transformer power supply. It is not the industrial instrument that needs to work online for a long time, but naturally it is better to use switching power supply.
Q:How to choose UPS power supply for industry?
The factory with UPS power supply also depends on the specific load of the electrical environment, if the electrical environment is not good, the frequency and voltage fluctuation, it is recommended to use the UPS high frequency power supply, and can use UPS power frequency imtex. We would also like to see the number of electricity load in general, large factories for three-phase four wire AC, some small factories are using 220 single-phase electric equipment, according to the specific electric phase to determine either UPS power model, the power UPS power supply: Renda online frequency single series, online a series of three type power frequency three and three single frequency online series, also the same frequency
Q:Which is better to use TL494 and UC3842 as industrial power source? Mainly in terms of stability and efficiency!
In terms of stability and efficiency, there is no way to distinguish between, depending on the specific parameters you do power, 100W, including the proposed UC3842 flyback, 100W-500W proposed to use UC3842 forward, 500W-1000W suggested using TL494 half bridge
