- Q:PIC microcontroller used in the industrial field, its power supply switching power supply and B0505 isolation module, anti-interference performance is better, feasible?
- Isolation is not directly related to interference immunityIf the interference source cannot be removed and the interference source is removed, the transmission path is an effective method. The power supply interference can be considered using a power filter
- Q:Why is the power supply of industrial control system mostly DC24V? Why not 17V? 11V?
- This is the industrial standard, just like other industrial standard parts. This is related to the actual battery 1.5V, the lead-acid battery is also 3V, an interval related, 24V just have a combination. 11V, 17V, if you use batteries, how many batteries do you use? Suspended in midair。No standard power supply, accessories to go there to find ah? Can not a product, a power it?
- Q:What are the applications of intermediate frequency power supply in industrial field?
- In the application of heating the workpiece in the heating process, heating of the metal, the workpiece can be reached inside and outside a temperature range. The utility model is also used for heating, casting, stamping, extruding, rolling, etc. of metal materials before processing.Because if furnace short heating time, heating almost no or only a small amount of oxide skin, so the skin caused by oxidation of weight loss is less than 0.5%, while the oxide gas caused by weight loss is as high as 20%, coupled with the loss and waste pickling is great. Therefore, the use of medium frequency power supply can greatly improve efficiency, and easy maintenance, reduce labor intensity, and facilitate the realization of automation.Due to the high skin effect, the density of the induced current decreases gradually from the surface to the interior. With the same material, the higher the frequency, the faster the current density drops from the outer surface to the interior.
- 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:What is the allowable fluctuation range of industrial standard 380V power supply voltage?
- The voltage fluctuation range is as follows:The sum of the positive and negative deviations of the supply voltage above and above the 35kV shall not exceed l0% of the nominal system voltage. Note: if the electric voltage is up and down, the same number (all positive or negative), the absolute value of the larger deviation is used as the basis of measurement.10, kV and below three-phase supply voltage deviation is nominal system voltage, taxi 10%.
- Q:Is the switch power supply for industrial instrument power good or transformer good?
- The guy upstairs wrong, 1: switching power supply unless the resonant switching power supply is more expensive, otherwise it's interference than the general circuit transformer is composed of the bigger, you go to see the high-end audio switching power supply (why not have a dedicated, open loop resonator) 2: the so-called "lightning protection switching power supply the) is only one or two varistor in parallel with the input end of the lightning lightning to see what kind of way, limited function, little difference between this and the transformer, the transformer and the posterior pole voltage stabilizing circuit. The output voltage of the transformer is AC 3, want to get stable DC voltage output circuit must be added, so the voltage is more stable that depends on your components and circuits, switching power supply transformer must be better than not good.
- Q:How to choose UPS power supply for industry?
- The UPS power supply, has been successfully applied to the more than 300 factory level customers, is committed to providing a full set of electrical energy for factory level customer solutions, 11 UPS power supply, stable performance, first-class quality, each UPS power factory, have gone through at least 40 tests of stability to ensure that the vast reaches of products the hands of customers, the UPS power supply, UPS power plant was the best partner program.
- 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
- Q:What are the types of power used in industrial UPS? What type of UPS power can take the place of it?
- Powerware's new Powerware 9120 series, with extremely wide input voltage range, even in the extreme environment of electricity, can work properly, reduce the discharge times of the battery, and the battery life prolong. Because of the intelligent design, P9120 has the function of frequency selection, and it can adapt automatically whether it is 50Hz or 60Hz.P9120 is equipped with LCD LCD display, which can monitor and monitor the critical information of UPS running status, battery backup time and display the adjustment of UPS parameters in real time. At the same time, P9120 uses battery management patent technology ABM, which can extend battery life by more than 50%. P9120 series is also equipped with USB/RS-232/ communication expansion slot, a variety of interfaces to meet the user's choice of a wide range of communication.
- Q:I have the 24V switch power outlet end of "+" and "-" two, the voltage between the two is 24V, connected with the electrical components of the loop, which "-" it is necessary to connect with the cabinet ground (that is, ground wire) connected? What's the difference between grounding and ungrounded? What kind of influence does the two kind of situation bring to the electric appliance in the actual use? Please help me master the answer!
- The switching power supply is the use of modern electronic technology, the control switch turn-on and turn off time ratio, maintain a stable output voltage power supplies, switching power supply from the general pulse width modulation control of IC and MOSFET. With the development and innovation of power electronics technology, switching power supply technology is also constantly innovation.
