Q:Switching power supply life is generally how long?
of course, if the quality is not Good words! May also be a 7-8 years or so! Suggestions or 7 years for a bar! The Before I bought a rich inside the switching power supply! Use now! Is it good!
Q:What is the impact of the refrigerator on the refrigerator?
This will cause the compressor to stop and stop frequently, affecting the life. In fact, the refrigerator 24 hours (working hours generally do not take 12 hours), only less than 1 kWh. To save power, start from the other side. Put the hot things in the fridge and so on, a lot, you can find your own online.
Q:Switching power supply gnd is doing
Is a place for the application of the assumption that for the power supply, it is a negative power supply. It is different from the earth. Sometimes need to connect it with the earth, and sometimes do not need, depending on the circumstances
Q:What is the difference between what we usually call switching power and ups?
Switching power supply is a simple power supply, and the transformer power supply name difference. High efficiency and stable operation Wide voltage range. UPS on the complex it includes switching power supply function is different from the power supply. It consists of step-down circuit boost circuit charging circuit detection circuit and battery. It is widely used in emergency power systems, protection of computer information, security for the security system. Remember the crash in Wenzhou? Power failure caused by automatic monitoring paralyzed, and this time on the use of the UPS.
Q:How is the switching power supply fixed?
Side also has a fixed position to install, increase the installation of 90 ° bracket. L: then 220v AC line of fire N: then 220v AC zero line FG: then the earth G: DC output ground + 5v: output + 5V point of the port ADJ: is the output voltage within a certain range, the switching power supply output voltage is the original factory is fixed, that is, the nominal rated output voltage. Set this potentiometer allows users to the actual use of the situation in a smaller The output voltage is adjusted in the range. It is not necessary to adjust it in general.
Q:Will the electronic prawns, the general switching power supply can accept the emotional load?
Yes, the actual use of a lot. When using the attention, the output connected to a switch, stop, do not directly off the power, you must first disconnect the switch, to avoid inductive load current after the sudden change in the potential to damage the power supply. The above matters, even if other power supply, should be kept as far as possible.
Q:Switching power supply fan does not turn, it was encountered this problem?
Look at your fan a few lines, two words, do not turn is bad, or broken
Q:Switching power supply inductance
Generally do not put the frequency of work can be heard on the frequency, that interference will be very painful!
Q:Who can help me choose a switch power supply model 220V AC / 10V DC
This type of power Taobao is more than, as long as the input (power 10V DC) can be.
Q:Your company's switching power supply through what channels to purchase?
Hello, now on the market power varies, the choice of power directly determines the product itself is good or bad, good power mainly to see the program, device platform, production technology, testing standards and a series.
We have various advanced equipment, such as wave soldering and reflow soldering machine, RoHS testing, environmental testing system, etc. Only top international brand components are adopted for our key parts to ensure long lifetime and high reliability. Each unit is given full load burn-in test.
