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: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:What is the difference between computer power supply and industrial switching power supply? My points run out, thank you enlighten prawns. Thank you

It is generally believed that the power supply used in industrial equipment can be called industrial power supply. Also refers to those larger power, more power functions.

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: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

According to the connection mode of switching devices in the circuit, the switching power supply, which is widely used at present, can be divided into three major categories: series switching power supply, parallel switching power supply and transformer type switching power supply. Among them, the switching power supply transformer (hereinafter referred to as the transformer switching power supply) can be further divided into: push-pull, half bridge, full bridge etc; according to the phase excitation and the output voltage of the transformer, and can be divided into: forward, flyback, single and double excitation type excitation type variety; if from the use of come, also can be divided into more types.

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?

General power monitoring software works only in one operating system. And P9120 comes with the power monitoring management software LanSafeIII/FailSafe III, can adapt to a variety of operating systems, and can work across platforms.Highlights: battery management technology ABM

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.
