Now with the machine most people do not attach importance to the power of this thing, think as long as the power is enough, in fact, the power is one of the most critical components of the computer, is the security of computer stability, the following introduction to select the power to pay attention to the problem. 1

WWW why cooling time follow power supply related recommendationsThe Frequency Conversion Power Supply can run normally for a long time without the regular maintenance and maintenance by the user. Just like if the air conditioner is used for a long time without cleaning and maintenance, its cooling effect will be reduce

. Generally, after more than a dozen cycles, the voltage at both ends of the energy storage filter capacitor can be charged to the maximum value. For example, if the electrical inductance of the transformer secondary coil is 10-1000, and the capacity of the energy storage filter capacitor is 10000-1592, the following formula can be obtained: ω =, or F = Hz, T = 628 microseconds, 1/4 cycle is 157 microseconds; set the switching power

Troubleshooting of starting and welding by hard disk power supply interface The author of a computer post more smoothly, but the system does not detect the hard drive, and can not enter the system, the author began to suspect that the system file damage. So ready to reload the system, but still can not detect the hard drive, so the decision may be hard disk hardware problems, such as hard disk

One, skillfully set the power off button The power button under the Start menu is free to set, we can right-click on the Start button, select Properties to pull up the menu on the right, and then set the Drop-down menu in power button action, and click OK to finish. Small series I usually restart the computer more often, so, set to restart the key, convenient a

The most common problem encountered when using a USB device is the power source-the power supply is insufficient. to effectively solve the fault of insufficient power of the USB interface, this article specifically summarizes some countermeasures, I hope it will be useful to you! How to identify USB

Generally speaking, when the computer is working properly, the sound is very small, in addition to the hard disk read and write data emitted by the sound, mainly the cooling fan sound, especially the switching power supply fan emits the loudest. Some switching power supply after long-term use, in the work will produce

The difference between electric vehicles and traditional fuel vehicles lies in the power part, which is also the core part of electric vehicles. A pure electric vehicle system usually consists of three systems, namely, the power drive subsystem, the main energy subsystem, and the auxiliary control subsystem. The electric drive subsystem consists of an electronic controller, a

Product Introduction Mcp100It can provide up to 85% of the charging power, and output stable 27vdc/1.5a, 27vdc/3A two-way voltage current, the output voltage is in 24vdc ~ The 28vdc can be continuously adjustable to meet different charging voltage requirements. The ripple noise is basically stable below 100mV to ensure that the backend user system is not disturbed. It has good low temperature working characteristics, available at-40 ℃ ~ Working contin

UPS Power is what is actually not a special understanding for most people, today I will explain from three aspects of UPS power is what.First UPS English full name is "uninterruptible power supply", that is, the Chinese uninterruptible power

Recently I have read several posts about power switching, so I will share with you the power switching circuit used in one of my projects. Thank you.Features:1. Supports touch switch and self-locking Switch2. Support automatic power-on of external power supply (which can be

Q: What is the difference between a frequency conversion power supply and a frequency converter? I believe everyone has many questions. I only know that the frequency conversion power supply is not the same product as the frequency converter, but I don't know much about it, some friends may know that the inverter is us

Inverter power supply has been very widely used in various industries, inverter power supply inside the core components have a lot, IGBT module is the most important part of the inverter power supply, in the inverter

In the modern manufacturing industry, the application of industrial machines has expanded to a wider range of fields. The reliability of industrial machines is the main technical indicator to measure the quality of industrial machines. Frequency Conversion Power Supply manufacturing and application should pay attention to the reliability problem from the very beginning. The reliability of the Frequency Conv

The filter capacitor can also be called the DC capacitor, which is one of the important components in the inverter power supply. It has a unique role in it. In the future, we will be able to better understand the frequency conversion power supply. So let's talk about the role of the filter capacitor in the inverter

The dense components have filled the power supply. At the mains input end, we can see EMI filtering circuits with better results. We can even see anti-magnetic rings from the inside to the online, so we can see a variety of painstaking efforts. At present, 3C Certification is one of the essential certifications for power s
