The main working process of UPS power supply is filtering and rectifying inverter. In addition, it also includes many auxiliary units, such as charger and battery, microprocessor, and communication interface. Because the UPS power supply is installed between the device and the mains

In the past, on-site cabling was very simple. The sensor can be either power-supply or passive. The power supply type requires 2, 3, or 4 cables, and the passive type requires only 2 cables. At the same time, the sensors are both analog-type and support 12, 24, 36, 48VDC, or 110, 220VAC voltages. The field controller p

1-5. Single-excited transformer Switching Power SupplyThe biggest advantage of transformer switching power supply is that the transformer can output multiple sets of different values at the same time, which makes it easy to change the output voltage and output current, you only need to change the turns ratio of the transformer and the cross-sectional area of the

When buying a computer, you are too concerned about the speed of the CPU, the memory capacity, the speed, and the hard disk capacity and speed, this is also the most transparent, and the majority of businesses are most willing to publicize and boast to use. However, we all ignore a very important issue. The power supply of the PC is the foundation for other components to work normally and stably for a long

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

Power Management Module ( PMM ) and power supply monitoring introductionPower Management Module and supply Voltage SupervisorI think power management and monitoring is a very complex and difficult to control part, not only involvesThe choice of source mode involves complex i

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

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

What is a frequency conversion power supply?The AC Variable-frequency power supply technology has been widely used in developed countries. Its principle is to convert the AC power in the mains supply through AC → DC → AC, and outp

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

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

Q : What are the problems caused by insufficient power supply? A: If the power supply is insufficient, IPC may be unable to start, Infrared night vision switch failed, NVR may be hard to boot and other abnormal problems, please be sure to use the specifications required po
