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: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 allowable fluctuation range of industrial standard 380V power supply voltage?

Industrial standard 380V power supply voltage fluctuation range is plus or minus ten percent

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: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: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:Which brand of industrial switching power is good, including imported, not modular power?.Refuse advertising

MeanwellMany domestic copies of it.Foreign switching power supply is relatively small, more than 75% of the world in the mainland.

Q:Why is the power supply of industrial control system mostly DC24V? Why not 17V? 11V?

At the same time can reduce the current power, and is a common multiple of the majority of the 24, the standard of course should be considered and a variety of battery, either 2V or lead-acid batteries commonly used 1.2V, 1.5V and 3V batteries are good combination. With a series of standards, it's good to swap everything at the critical moment.

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 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
