- Q: What are the types of power used in industrial UPS? What type of UPS power can take the place of it?
- Mainly look at the INPUT input and OUTPUT output of these two parameters, you can refer to the value behind it to find
- Q: How to choose UPS power supply for industry?
- UPS power battery size determines the load power supply time, concrete is according to the needs of the load to be, for example: if the injection molding machine you need to supply 1 hours to ensure the normal stop at power off, then our battery size depends on the battery matching the appropriate injection molding machine power the size of the UPS power group, 11, UPS battery, can also have their customers to buy.
- 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: What is the concept of switching power supply in electronic circuit single chip microcomputer? What's the use of industry? What is the working principle? Must adopt
- A variety of switching power supply, its working principle is not the same, but the fundamental principle are basically the same, namely: switching power supply is the use of electronic switching devices (such as transistor, FET, SCR thyristor, etc.) through the control circuit, the electronic switching devices constantly "on" and "off" so, the electronic switch on input voltage pulse modulation device, so as to realize DC/AC, DC/DC voltage, and output voltage adjustable automatic voltage regulator.
- Q: Which is better to use TL494 and UC3842 as industrial power source? Mainly in terms of stability and efficiency!
- The 3842 is a single output switching power supply generally use this, TL494 is a dual output, can be made into complementary output, also can be made into a single output is mainly used in computer power on.3842 simple, 494 point complex stability and efficiency! The main design is power
- 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!
- Industrial 24V switch power outlet "-" it is necessary to connect with the ground. The negative grounding of the power supply can prevent differential mode interference to a great extent and improve the stability of the circuit.
- Q: PIC microcontroller used in the industrial field, its power supply switching power supply and B0505 isolation module, anti-interference performance is better, feasible?
- Which model you use PIC, switching power supply to the chip power supply, no problem, the key is to add single-chip power filter to do a good job.Relay output should be optically isolated and so on. B0505 output measurement must have a small load, and input and output must add filter capacitor, otherwise the interference is very big.
- Q: What is the allowable fluctuation range of industrial standard 380V power supply voltage?
- 220V single-phase power supply voltage deviation is nominal, called system voltage +7%, - 10%.Users with special requirements for the allowable voltage deviation of the supply voltage shall be determined by agreement between the supplier and the power supplier.
- Q: What is the difference between computer power supply and industrial switching power supply? My points run out, thank you enlighten prawns. Thank you
- From the nature of the power supply, there is no difference. But functionally. The computer power supply can be an industrial power supply. Industrial power supply is wider and more power sources are used as industrial power supply.
- 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
